GaAs optoelectronic integrated receiver with high-output fast-response characteristics

For obtaining high-output level and high-speed response in a GaAs-based optoelectronic integrated receiver, a circuit involving a two-stage amplifier was first designed and fabricated. A high sensitivity of 400 V/W has been achieved while preserving a high-speed response of 2-Gbit/s nonreturn to zero (NRZ).
