An InP-based monolithic integrated photoreceiver with a bandwidth of 27 GHz is presented. The device consists of a waveguide fed pin-photodiode and a traveling wave amplifier with coplanar waveguides based on four InAlAs/InGaAs/InP-HFET. The integration concept, receiver design, fabrication process and characterization are shown. The presented concept(More)
Hybrid as well as monolithic integrated /spl lambda/=1.55 /spl mu/m optic/millimeter-wave converters were developed and investigated experimentally based on detailed microwave simulations. Both converters working near 60 GHz showed responsitivities of about 1 A/W in good agreement with the simulations.
