摘要：

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