Abstract

Edge-emitting coupled-cavity semiconductor lasers employing a deeply etched Bragg reflector at one facet have been realized. The sidemode suppression ratio (SMSR) and wavelength tuning were investigated as a function of low level current injection. A single-mode tuning range of 3 nm centered around 977 nm displaying an SMSR better than 20 dB was obtained for tuning currents in the milliampere range.
