Monolithically Integrated Dynamic-Single-Mode Coupled-Cavity Lasers

Abstract

Recent results with cleaved-coupled-cavity (C3) lasers have soundly demonstrated the viability of the coupled-cavity concept far tunable single-frequency semiconductor lasers[1,2]. Previous work with monolithic groove-coupled two-section lasers[3,4] suffered in performance because of the use of gain-guided base material, which foiled both CW operation and the realization of extremely dean longitudinal mode spectra.
