We report the development of racetrack-cavity semiconductor ring lasers that operate unidirectionally by means of an active crossover waveguide. These racetrack-cavity lasers show improved performance over previous circular-cavity unidirectional ring lasers with continuous-wave single-frequency output powers of [ge]10 mW, and with up to 99% of the lasing output emitted from the preferred ring direction.
