Eight-Channel Microdisk CW Laser Arrays Vertically Coupled to Common Output Bus Waveguides

摘要

1.6-nm spectrally spaced eight-channel semiconductor microdisk laser arrays are presented, where high-disk lasing modes are vertically coupled out through a common bus waveguide. The spectral channel spacing is achieved by varying the disk resonator radii from 10.6 to 10.95 micrometers. Typical linewidth of 0.25 nm and side-mode suppression ratio of -20 dB are observed under continuous-wave lasing operation near lamba = 1.51 micrometers. This is the first demonstration of integrated microresonator laser arrays.
