This chapter is concerned with the design, fabrication, and characterization of deeply-etched III-V semiconductor ring lasers (SRL) whose radius is scaled down to sub-10μm values. The laser threshold performances are experimentally investigated for different laser geometries. Compact racetrack-shape SRLs are shown to exhibit robust unidirectional bistable operation with direct extinction ratio and single mode rejection ratio of 20 and 30 dB, respectively.
