Abstract: We present the study of the emission characteristics of a semiconductor circular ring laser diode with a Y-junction output coupler. Instead of laser output from Y-junction coupling terminal, a confined laser beam output was also observed at non-waveguide region due to optical nonlinearity effect of the multi-quantum wells active median. It showed that except for the circular ring resonator mode, much complicate modes were excited from both output terminals. A hybrid resonator formed by conjugated reflection is suggested to explain the features of output characteristics. In addition, L-I and spectrum characteristics of both output terminals of these hybrid resonators were analysed to explore the detailed mechanism of these hybrid resonator.
