Abstract

InGaAsP/InP rectangular ring lasers based on active vertical coupler structure are demonstrated in terms of loss-reduction. Varied thresholds for different configuration devices with different coupling current have been measured. The smallest threshold current of 75mA has been achieved in the device with the coupler length of 300μm and coupling current of 30mA. Such variation has also been calculated assuming different fabrication loss. Their loss mechanisms have been investigated based on threshold analysis, which should benefit to further optimize loss-reduced semiconductor polygon ring lasers based on active vertical coupler structure.
