A TWA optical receiver with hybrid integrated InP detector

Journal Article (Academic Article)

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
