   Abstract:
   To investigate the usefulness and feasibility of the TWA structure for low cost wide band system applications we designed a TWA optical receiver using low cost commercial process, the measured results show it is possible to achieve an 18 GHz bandwidth with a 7 dB gain using low cost GaAs MESFET process with a 20 GHz cut-off frequency, we also try, for the first time, the operation of an hybrid integrated OEIC using a fabricated TWA optical receiver and a thin film photodetector 50 μm in diameter. These results demonstrate that it is feasible to apply TWA in low cost wide band systems and to integrate, in a a hybrid circuit, wide band MMIC with thin film detectors for inexpensive high speed OEICs
