Fabrication and characterization of Y-junction-coupled S-section InAs/InGaAs/GaAs quantum-dot ring lasers with low threshold current density and high unidirectionality is reported. The new design suppresses unwanted counterpropagating modes more effe

Semiconductor ring lasers show great promise for rotation sensing through the Sagnac effect of frequency shifting. Ensuring a controlled unidirectional operation of ring lasers can greatly benefit this application. An S-section racetrack design for s
