| Popis: | First monolithically integrated ridge-waveguide InAs/InGaAs quantum-dot ring lasers are fabricated and characterized. Enhanced by a forward biased S-section waveguide, stable traveling-wave (unidirectional) operation with record suppression ratio of counterpropagating waves approaching 30 dB is demonstrated. |
