State funding provider:
TA CR - Technology Agency of the Czech Republic (TA ČR)

Project TH01020276 - Flexible 2D & 3D polymer photonics structures is solved with a finance support of TA ČR in the programme EPSILON, the programme for support of applied research and experimental development.

 

Participants in the project:
CTU in Prague (ČVUT) - the contractor
OPTOKON, a. s., University of Chemistry and Technology, Prague - other participants in project
Period for project solving: 1st July 2015 – 30th June 2018

Project objectives:

The scope of the project is design and production of polymer planar bendable structures, which allow transmittion of optical signal between opto-electronic modules such server components at data centres or control units in cars, plain or helicopters.

The aim of the project is to develop chanell multi-mode waveguides and splitters of Y-like shape (1×2) on a surface of printed circuit boards (FR 4) and bendable substrates (bendable glass or plastic).Signal will propagate through waveguide in a form of infrared radiation of wavelengths standard in telecomunication: 650 nm, 850 nm, 1310 nm and 1550 nm.

The project is initiated mainly by a need of higher data links throughput and signal quality for short distances, which is important at data and computing centres. Another important improvement of the project goal is an usage of optical links in aircraft. This would bring weight reduction as well as deprive of external electromagnetic interference. Advantages of optical data links over metal data links are rather widther transmission band (and therefore higher throughput), remarkable reduction of power consuption is allowed, absence of cooling system and less spatial demanding.

Optical waveguides on electronic circuit board surface will allow realization of true opto-electronic (i.e. hybrid) circuits on a very one substrate. Optical waveguiding structures on bendable substrate will allow an interconnection of optoelectronic modules (rack-to-rack, board-to-board as well as chip-to-chip).

Four lithographical methods are used at research: optical UV-lithography, Laser Beam Writing, InkJet printing and 3D printing. Polymers such as SU‑8, Micro Resist EpoCore & EpoClad, OrmoClear, NOA or LightLink are tried to use. The final product will be able to operate under 5 – 80 °C, will be length of 4 – 50 cm and presumption of its insert loss is 1 – 2 dB·cm‑1. Transmition speed should be between 10 Mb/s and 1 Gb/s (length, shape and purpose dependent). Waveguide connection is discused at present, but standard MPO/MTP connector seems to be the best solution. MPO/MTP optical connector allows to bear up to 24 waveguide in one.

Results of the project are three prototypes of channel waveguides on FR 4 surface, one prototype of polymer bendable optical waveguide and one prototype of bendable optical splitter. At least one of results is going to obtain a legal protection.

 

Project data:
TA02010825 - Widely tunable mid-infrared signal source for spectroscopy and metrology (2012-2014, TA0/TA)

State funding provider:
TA0 - Technology Agency of the Czech Republic (TA ČR)
TA - Programme of applied research and experimental development ALFA (2011-2016)

Participants in the project:
OPTOKON, a.s. - the contractor
Institute of Photonics and Electronics of the Academy of Sciences of the Czech Republic, v.v.i. – another participant in the project

Project objectives:
The aim of the project is to develop a widely tunable source of mid-infrared coherent radiation. The source will be based on different frequency generations in nonlinear crystal. It exploits the know-how of the Institute of Photonics and Electronics in the field of high-power lasers and periodically poled crystals. The source will generate a narrowband tunable signal in the spectral range of 3200-3800nm with mW power. It will be useful for spectroscopy, metrology and medical diagnostics.

The source has potential application in technology for processing plastics and polymers, non-invasive medical diagnostics, minimally invasive surgery, high definition laser spectroscopy, detection of trace elements and weights and measures, which allows the transfer of measuring techniques and good-quality communication wavelengths to midIR area. For all of these applications there is the key performance and stability narrowband signal of a well defined wavelength. Both can be achieved due to the high-quality and cost-effective sources of signals that are available on the default 1060nm and 1550nm wavelengths.
The objective will be achieved by 31 December, 2014.

 

Project data:
FR-TI4/580 - *Hybrid telephone exchange with direct connection to optical network (2012-2015, MPO/FR)

State funding provider:
MPO - Ministry of Industry and Trade of the Czech Republic

Participants in the project:
OPTOKON, a.s.-the contractor
TechnicalUniversity in Brno, Faculty of electrical engineering and communication technologies, Institute of Radioelectronics- another participant in the project

Project objectives:
The subject of software solutions for the Hybrid PBX telephone project with direct connection to optical network design and implementation is a decentralized, semi-autonomous PBX for a VoIP service provider and broadband internet access, using optical connections. The market share is currently growing and is expected to blanket the introduction of FTTH (Fiber To The Home) services. With decentralization and autonomy, the client side panel will be allowed to be used in addition to the PBX for small and medium businesses.

The main objective of the Hybrid telephone exchange project with direct connection to the optical network is the design and implementation of a decentralized, partly autonomous telephone switch specified for VoIP services and broadband Internet providers, who use the optical connection. Their share of the market is currently rising and is expected to blanket the introduction of FTTH (Fiber To The Home) services. Due to the decentralization and autonomy of individual parts, evenly spaced performance, resistance to outages on the network and provide selected services will be guaranteed, even when disconnected from the network. Prototypes of thee telephone exchange operator and the client part of the telephone exchange will be created, together with a set of testers for the preparation of production equipment. It will also form part of the user control software solution used to configure the telephone exchange, which is planned to be used separately.

The proposed hybrid telephone exchange will consist of two logical parts: the operator part and the client part. The central office operator will be located in the premises of the service provider, and several client components will be connected through fiber-optic cables. This will allow relatively efficiently and inexpensively services to cover large populated areas. The client portion will be placed in the building and will be led by polymer optical fiber to individual clients. This procedure also assumes the possibility of additions to the client part of the card for analog lines. The client portion of exchanges will be largely autonomous with its own telecommunications subsystem and will be suitable for small and medium-sized businesses as a replacement for the centre. As a component of an ensemble, the hybrid telephone centre property assumes the possibility of granting access to the internet. This considerably increases the number of potential candidates.

 

Project data:
FR-TI4/696 - *Localization and classification of vibrations by scattered fiber optic sensor over long distances (2012-2015, MPO/FR)

State funding provider:
MPO - Ministry of Industry and Trade of the Czech Republic

Participants in the project:
OPTOKON, a.s.- the contractor
TechnicalUniversity in Brno, Faculty of electrical engineering and communication technologies, Institute of Radioelectronics- another participant in the project

Project objectives:
The scope of the project is the design of methods and development of a monitoring system for remote checks on the large piping systems for transporting media (gas, oil, water, etc.) with the scattered sensor based on optical fibers with the capability of detection, classification and localization of the source of vibrations, that for example, could represent a breaching of the pipeline or the movement of intruders in a monitored area, say in the range of about 100 km with classification regularity greater than 80% and a location accuracy of tens of meters. The system will include both a sensory part and a supervisory part, both interconnected by terrestrial or satellite data networks. Environmental protection from possible oil contamination and minimization of the danger of leaking oil or gas combustions are the other benefits of the project.

The aim of the project is the design, implementation and verification of the system for remote control of large-scale pipeline systems to transport media (gas, oil, water, etc.) with the help of the spread of optical fiber based sensors. The use of optical fibers as sensors is offered as standard due to their presence along the pipeline systems. This creates an optical sensor network without unnecessary costs for installing and connecting special sensors to the communication infrastructure or laying special optical fibers. A monitoring system will be able to classify and locate the source of the detected vibrations, which could disrupt the piping, in the range of about 100 miles to accuracy greater than 80% and with an accuracy of tens of meters. The system will include elements representing both the sensorial system and surveillance center, and the connected data network terrestrial or satellite type. Another benefit of the system, due to the timely detection and precise localization of pipeline systems and environmental protection which, in the case of a pipeline that could be contaminated, is the elimination of the risk of igniting escaped gas or oil.

The resulting system will be possible due to its versatility, in addition to reviewing the extensive pipeline systems, anywhere where there are fiber optics for sensing mechanical vibration – for example, in the security sphere as a sensor array to detect violation of the perimeter.
