40Gbit/s coherent optical receiver using a Costas loop.
A highly integrated 40 Gbit/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 × 10mm(2), and a 1.1 G...
متن کاملTime Domain Model for Costas Loop Based QPSK Receiver
A complete Matlab model is made for a millimeter wave wireless communication system including a four-phase Costas loop for carrier recovery and QPSK demodulation. Simulation results are presented to demonstrate the dynamic behaviour of the Costas loop and the effects of noise, linearity and bandwidth limitations. The time domain results are compared to the frequency domain transfer function der...

متن کاملCoherent Receiver Based on a Broadband Optical Phase-Lock Loop
We propose and demonstrate a 1.45GHz bandwidth optical phase-lock loop receiver for linear optical phase demodulation. Using the receiver in a link application, a spurious free dynamic range of 125 dBHz is measured at 300MHz. ©2007 Optical Society of America OCIS codes: (250.3140) Integrated optoelectronic circuits, (060.1660) , Coherent communications (060.5060), Phase modulation, (060.2360) F...
