Optical injection locking at sub nano-watt powers

Reflection-mode optical injection locking.

A novel model including the interference effect of master laser reflection is established for reflection-mode optical injection locking. This model sheds insight on the physical origin of some rather distinct but unexplained modulation characteristics of optical injection-locked vertical-cavity surface-emitting lasers (VCSELs), including data pattern inversion in on-off keying modulation, a lar...

Optical Injection Locking of Vertical Cavity Surface Emitting Lasers by

Optical 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...

Injection Locking of VCSELs

Injection locking has been actively researched for its possibility to improve laser performance for both digital and analog applications. When a modulated follower laser (also termed “slave” laser) is locked to the master laser, its nonlinear distortion and frequency chirp may be reduced. As well, the resonance frequency can increase to several times higher than its free running case. In this p...
