A wavelength tunable V-cavity laser (VCL) employing integrated thin-film heaters is reported. The laser is fabricated by a simple process with no grating or band-gap engineering. A single-electrode-controlled wavelength tuning of 32 channels is achieved by experiment. with a tuning efficiency of 0. https://www.bekindtopets.com/deal-find-Equi-Jec-6-best-super/
