Abstract
We report the first observation of single longitudinal mode operation in multiple-stripe injection lasers. The lasers are fabricated by channel etching and Zn diffusion in three-layer double heterostructures grown by organometallic vapor phase epitaxy. Linear output characteristics have been observed to cw output powers of 180 mW (uncoated facets) at room temperature with good stripe-to-stripe uniformity. Operation in a single longitudinal mode has been seen to 60-mW output and is evidence for strong stripe-to-stripe coupling.Keywords
