Abstract
This paper presents a facetless, tunable laser operating near 1575Â nm, as well as a theoretical model predicting spectral features of the laser. The lasers were fabricated without regrowth or advanced lithography techniques, and are based on MMI couplers and etched facets. Coarse vernier tuning was achieved over a range of 25Â nm, while fine, thermal tuning was also demonstrated over a range of 1.5Â nm. SMSR values of 25Â dB and higher were observed, with a measured laser linewidth of 600Â kHz.
