We investigate the below-switching-threshold-properties of a helically bistable laser with helical wave injection. We find that this system shows amplification of the injection signal (optical transistor). We measure the amplification as a function of modulation frequency and frequency offset between the amplifying laser and the injected radiation. Good agreement is found with the corresponding laser model.

Abstract
We investigate the below-switching-threshold-properties of a helically bistable laser with helical wave injection. We find that this system shows amplification of the injection signal (optical transistor). We measure the amplification as a function of modulation frequency and frequency offset between the amplifying laser and the injected radiation. Good agreement is found with the corresponding laser model.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
