25-Gbps 5×5 mm chip-scale silicon-photonic receiver integrated with 28-nm CMOS transimpedance amplifier

We have developed a compact silicon-photonic receiver integrated with a CMOS transimpedance amplifier (TIA) chip and demonstrated 25-Gbps error-free operation. A minimum sensitivity of−9.7 dBm and a consumption power of 2.3 mW/Gbps were obtained.
