Monolithically integrated heterodyne optical phase-lock loop with RF XOR phase detector.
We present results for an heterodyne optical phase-lock loop (OPLL), monolithically integrated on InP with external phase detector and loop filter, which phase locks the integrated laser to an external source, for offset frequencies tuneable between 0.6 GHz and 6.1 GHz. The integrated semiconductor laser emits at 1553 nm with 1.1 MHz linewidth, while the external laser has a linewidth less than...
متن کاملA Photonic Integrated Circuit for a 40 Gbaud/s Homodyne Receiver Using an Optical Costas Loop
A highly-integrated optical Costas loop has been realized within a footprint of 10×10 mm 2 by using a photonic integrated circuit. 40 Gbaud/s data demodulation has been achieved. Keywordsphotonic integration, coherent receiver; Costas loop; phase-locked loop Coherent fiber optic communication is receiving a lot of interest recently. Compared to traditional optical receivers that are used for di...

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...
متن کاملOptical injection locking and phase-lock loop combined systems.
Optical injection locking and optical phase-lock loops have been used for laser synchronization. The use of a combined optical injection locking and phase-lock loop system is proposed here. We have taken into account the modification of the slave laser phase response induced by the injection locking to calculated the phase-error signal spectrum and the phase-error variance for an optical inject...
