Abstract

A wideband resonance-type optical receiver (WROR) is proposed. It is based on inserting inductance in the feedback path of transistors to improve the frequency bandwidth and noise characteristics of the ROR in the high-frequency range. The noise characteristics of conventional and resonance-type optical receivers are evaluated by considering the series resistance of photodiodes. The double-balanced wideband resonance-type optical receiver is also evaluated. Its frequency bandwidth is 5-12 GHz. Finally, a 5-Gb/s optical CPFSK modulation and demodulation experiment is carried out using this optical receiver
