Continuous-wave operation of a fully tunable compact microring twin-laser array is demonstrated for the first time. The two active microrings, with radii of 70μm and 74μm, are vertically- coupled to a single passive waveguide. Tuning of the current facilitates a wavelength separation from 4.9nm to 6...
