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 کاملAn Example of a Hybrid System: Coherent Optical System with Costas Loop in Receiver–System for Transmission in Baseband
The possibility of hybrid system construction is considered in this paper. The coherent optical system is the constituent part of this system. The first part of the system is constructed in passband (optical cable is transmission medium), and the second part of the system is constructed in baseband. The heterodyne optical receiver is used as optical receiver. Estimation is not done just after d...
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...
