 Photonic Components for Future Wireless Systems
IPHOBAC‘s innovative Microwave Photonic technology is connecting the photonic and the wireless worlds. By integrating the best out of these two technologies, we enable broadband connectivity in communications, radar and instrumentation, says Andreas Stöhr, coordinator of the IPHOBAC project. [more...]

Photonics Components for Next Generation 60GHz Home Area Networks
 Using photonic components and OFDM modulation techniques,
IPHOBAC has successfully demonstrated bidirectional transmission of more than 1.25
Gb/s 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 15m
and a mobile station. A maximum data rate of 2.88 Gb/s is achieved with the
same system if radio propagation multi path effects are avoided. [more...]

Photonic 60GHz radio-over-fiber (RoF) access link with broadband wireless transmission up to 12.5 Gb/s
 Based upon advanced photonic components and radio-over-fiber (RoF) techniques IPHOBAC has developed 60GHz 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 12.5Gb/s. The system was successfully tested for short-range in-door as well as for medium-range out-door wireless transmission over distances up to 10m and 40m, respectively. When using high gain antennas and adequate RF amplifier we expect the maximum wireless distance the system could accommodate for 10Gb/s is in the range of several 100m even for heavy rain fall. IPHOBAC furthermore demonstrated the generation of a 10Gb/s 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 110GHz together with a small signal roll off of only 6dB and a high output power level up to -3.23dBm 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 69-112GHz. Here, the power fluctuation within the entire W-band was below 3dB and the output power level can be continuously tuned from -35dBm up to 0dBm. [more...]

 Integrated Photonic Functions
IPHOBAC is investigating mm-wave photonic system functions
that can be achieved using combinations of the developed
components. These photonic functions will be demonstrated
either through the use of hybrid integration offering a route
towards low cost miniaturisation or by laboratory bench demonstration. [more...]
