1.5 μm compressive-strained multiquantum-well 20-wavelength distributed-feedback laser arrays

Abstract

The wide gain spectrum of compressive-strained multiquantum-well active layers was used to fabricate 20-wavelength distributed-feedback laser arrays. A record wide wavelength span of 131 nm in the 1.5/μm wavelength region was demonstrated. The maximum intrinsic modulation response, measured by a parasitic-free optical modulation technique, reaches 16 GHz.
