摘要：

A highly integrated 40Gbit/s coherent optical receiver is reported using a Costas loop as a homodyne optical phase locked loop (OPLL). A photonic IC, an electrical IC, and a hybrid loop filter are characterized, and the feedback loop system is fully analyzed to build a stable homodyne OPLL. All components are integrated on a single substrate within the compact size of 10 x 10mm(2), and a 1.1GHz loop bandwidth and a 120psloop delay are achieved. The binary phase-shift keying receiver exhibits error-free (BER<10(-12)) up to 35Gbit/s and BER<10(-7) for 40Gbit/s with no latency, and consumes less than 3W power.
