Um diodo laser bloqueado no modo de pulso de colisão de 160 GHz (CPM-LD) foi estabilizado pela injeção de um trem de pulso de laser mestre estável repetido na 16ª frequência subharmônica (9.873 GHz) da frequência de bloqueio de modo do CPM-LD. As medições da câmera Synchroscan Steak revelaram um trem de pulso claro com frequência de repetição de 16 vezes do trem de pulso do laser mestre para a saída CPM-LD estabilizada, indicando que a saída CPM-LD foi sincronizada com o laser mestre e que o jitter de temporização também foi reduzido. O jitter de temporização do CPM-LD estabilizado foi avaliado quantitativamente por uma técnica de conversão totalmente óptica usando a não linearidade da fibra óptica. Esta técnica é simples e possui largura de banda maior em comparação a uma técnica convencional, possibilitando medir com precisão o ruído de fase do trem de pulsos ópticos ultrarrápidos quando sua frequência de repetição ultrapassa 100 GHz. As medições do espectro de potência elétrica indicaram que a frequência de bloqueio de modo do CPM-LD foi exatamente bloqueada pela injeção do trem de pulso de laser mestre e que o jitter de temporização diminuiu à medida que a potência de injeção aumentou. O jitter de temporização foi reduzido de 2.2 ps em operação livre para 0.26 ps com uma potência de injeção de 57 mW, comparável à do laser mestre (0.21 ps).

Abstract: A 160 GHz colliding-pulse mode-locked laser diode (CPM-LD) was stabilized by injection of a stable master laser pulse train repeated at a 16th-subharmonic-frequency (9.873 GHz) of the CPM-LD's mode-locking frequency. Synchroscan steak camera measurements revealed a clear pulse train with 16-times repetition frequency of the master laser pulse train for the stabilized CPM-LD output, indicating that CPM-LD output was synchronized to the master laser and that the timing jitter was also reduced. The timing jitter of the stabilized CPM-LD was quantitatively evaluated by an all-optical down converting technique using the nonlinearity of optical fiber. This technique is simple and has a wider bandwidth in comparison to a conventional technique, making it possible to accurately measure the phase noise of ultrafast optical pulse train when its repetition frequency exceeds 100 GHz. The electrical power spectra measurements indicated that the CPM-LD's mode-locking frequency was exactly locked by the injection of the master laser pulse train and that the timing jitter decreased as the injection power increased. The timing jitter was reduced from 2.2 ps in free running operation to 0.26 ps at an injection power of 57 mW, comparable to that of the master laser (0.21 ps).
