Abstract

We report the first experimental demonstration of a single-electrode-controlled digitally wavelength switchable V-coupled-cavity laser with high side-mode-suppression-ratio (SMSR) in the 40dB range. Sixteen-channel and twenty-six channel wavelength switchable lasers with 100GHz spacing are demonstrated with the maximal SMSR of 40dB and 37dB, respectively. They do not require complex gratings, multiple epitaxial growths, or complex tuning algorithms. The device size is only 500μm×300μm. Such a simple, compact, and high-performance laser has great potential as a low-cost alternative to existing complex tunable lasers for wide deployment in optical networks and beyond.
