We report the observation of the emission of solitons from a semiconductor circular ridge waveguide ring laser with a Y-junction coupler. The light–current ($L$–$I$) characteristics of the soliton emission through the nonwaveguide region, which refers to the photovoltaic solitons, has a low threshold value and a high quantum efficiency compare to the emission from the Y-junction coupler, and the spectrum of the soliton emission is similar to that of a linear strip laser with multimode emission. The feedback light from the end facet of the Y-junction coupling section continuously enhances the excitation of the photovoltaic solitons through the nonwaveguide region until the lasing condition is reached. It is suggested that the circular ring laser can be an alternative channel to light wave control in integrated optoelectronic system.
