This paper presents a single-mode tunable laser operating in the L band. The facetless design, along with a regrowth-free fabrication that does not require high-resolution lithography techniques, contribute to make the laser a suitable candidate for monolithic integration with other components. Vernier tuning is demonstrated over a range of 47nm, with sidemode suppression ratio (SMSR) values over 30dB and a linewidth of 800kHz.
