CW room-temperature operation of Y-junction semiconductor ring lasers
Abstract
CW room-temperature lasing in Y-junction semiconductor ring lasers with radii as small as 50 microns is reported. The dependence of the threshold current density on device dimensions is examined for radii in the range 50-200 microns and for waveguide widths of 2-8 microns. From these quantum-well devices, about 1 mW of CW single-frequency TE-polarized lasing output is obtained.
