Up to 12.5 Gbit/s @ 60 GHz Wireless Demo

IPHOBAC has been displaying its compact 60 GHz Photonic-Wireless system at ICT 2008 - Europe's biggest research event for information and communication technologies. Our booth has been voted to be one of the best 10 demonstrations presented in Lyon. [more...]

Compact Photonic 30-325GHz Transmitter developed

The IPHOBAC project recently succeeded in developing compact photonic transmitter modules for generating continuous-wave signals in the millimetre-wave and THz frequency range. Tuneable signal generation in the frequency range of 30-325GHz is demonstrated, higher frequency operation is currently being investigated. The compact fiber-optic transmitter modules consist of antenna integrated 1.55µm travelling-wave photodetectors as well as of an optical lens for focussing the generated THz signals. [more...]

Modulators and Detectors

One of the ambitious goals of the European IPHOBAC project is the development of millimetre-wave high-power photodiode and modulator modules for communications, security/ radar and instrumentation applications. The activities are well balanced between technological chip fabrication and new package developments. [more...]

Photonic 60 GHz radio-over-fiber (RoF) access link with broadband wireless transmission up to 12.5 Gbps

Based upon advanced photonic components and radio-over-fiber (RoF) techniques IPHOBAC has developed 60 GHz RoF access links for short to medium-range broadband wireless data transmission. Using OOK modulation the IPHOBAC system achieved record wireless data transmission of up 12.5 Gbps. The system was successfully tested for short-range in-door as well as for medium-range out-door wireless transmission over distances up to 10 m and 40 m, respectively. When using high gain antennas and adequate RF amplifier we expect the maximum wireless distance the system could accommodate for 10 Gbps is in the range of several 100 m even for heavy rain fall. IPHOBAC furthermore demonstrated the generation of a 10 Gbps 16-QAM modulated mm-wave carrier using photonic vector modulation (PVM) techniques resulting in a more spectrally efficient system.

Ultra-Wideband Photonic Millimetre-Wave Synthesizers

Two photonic millimetre-wave synthesizers based on optical heterodyning in a high-power pin photodiode were realised in the framework of the IPHOBAC project. In a configuration featuring a coaxial W1 output port, a full frequency tunability from DC to 110 GHz together with a small signal roll off of only 6 dB and a high output power level up to -3.23 dBm were achieved. In a second approach including a waveguide coupled limiting amplifier, an even more flat frequency response was achieved for the frequency range from 69 - 112 GHz. Here, the power fluctuation within the entire W-band was below 3 dB and the output power level can be continuously tuned from -35 dBm up to 0 dBm. [more...]

Photonic Components for Next Generation 60 GHz Home Area Networks

Using photonic components and OFDM modulation techniques, IPHOBAC has successfully demonstrated bidirectional transmission of more than 1.25 Gbps over a radio-over-fibre system composed of a central station, 50 m of optical fibre, a remote antenna, an indoor radio propagation path of up to 15 m and a mobile station. A maximum data rate  of 2.88 Gbps is achieved with the same system if radio propagation multi path effects are avoided. [more...]
