Experimental demonstration of modulation bandwidth enhancement in distributed feedback lasers with external light injection
Xue Jun Meng,Tai Chau,Ming C. Wu +2 more
TL;DR: In this article, the frequency response of a semiconductor distributed feedback (DFB) laser under optical injection locking has been studied experimentally and it is shown that strong injection locking is very effective at increasing the relaxation oscillation frequency of DFB lasers.

Improved intrinsic dynamic distortions in directly modulated semiconductor lasers by optical injection locking
Xue Jun Meng,Tai Chau,Ming C. Wu +2 more
TL;DR: In this paper, the effects of injection locking on the nonlinear distortions of a DFB laser were investigated experimentally, where the second harmonic distortion and third harmonic distortion were measured as functions of modulation frequency for both the free-running and injection-locked laser.

Distributed balanced photodetectors for broad-band noise suppression
TL;DR: In this paper, a velocity-matched distributed balanced photodetector with a 50/spl Omega/ coplanar waveguide output transmission line has been experimentally demonstrated in the InP/InGaAs material system.
A novel monolithic distributed traveling-wave photodetector with parallel optical feed
TL;DR: In this paper, a novel monolithic distributed traveling wave photodetector with parallel optical feed to an array of individual photodiodes using an integrated multimode interference coupler was presented.
Suppression of second harmonic distortion in directly modulated distributed feedback lasers by external light injection
TL;DR: In this paper, the suppression of second harmonic distortion in directly modulated semiconductor distributed feedback lasers by optical injection locking has been experimentally demonstrated, and it has been observed over a wide range of bias currents and modulation frequencies.
