This letter 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, contributes to make the laser a suitable candidate for monolithic integration with other components. Tuning is demonstrated over a range of 47 nm, with side-mode suppression ratio values over 30 dB and a linewidth of 800 kHz.
