 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. IPHOBAC will provide photodiode and modulator chips & modules for different frequency ranges: broadband (DC-110 GHz), narrow-band (55-65 GHz & 75-110 GHz) as well as wideband (30-300 GHz) operation. Some details are listed below:
- Broadband (DC-110 GHz) and high-output power (>0 dBm) photodiode modules using a fi bre-optic package with w1-coaxial output connectors and integrated bias-T. Prototypes are already available!
- Narrow-band antenna integrated photomixers for operation at around 60 GHz and WR10 coupled photodiodes for 75-110 GHz operation. Ultra-wideband (30-300 GHz) photomixer modules with integrated planar antennas. The PD chips are mounted in novel fi breoptic packages providing wideband quasioptical millimetre-wave radiation.
- Reflective 60 GHz picocell transceivers with integrated optical amplifi er to boost both the received and transmitted optical signals.
- Broadband optical transmitter modules for mm-wave signals up to 100 GHz consisting of a high power DFB laser with 1.55 μm wavelength and an integrated ultra-high speed electro-absorption modulator.
