In this paper we outline recent results which combine defect mediated Photo-Detectors (PDs) in a Ring Resonator (RR) structure. By exploiting the multiple-pass of the optical signal through the detector, we are able to significantly decrease the size of the detector structure while maintaining good responsivity (typically 0.1 A/W). In such a geometry the detector bandwidth is not capacitance limited, while the leakage current is reduced toward 1 nA. We also show that these PDs may be used in the drop port of a RR to monitor the propagating signal. These devices have applicability in multiplexing and potential for integration with high speed modulation functionality.

Abstract

In this paper we outline recent results which combine defect mediated Photo-Detectors (PDs) in a Ring Resonator (RR) structure. By exploiting the multiple-pass of the optical signal through the detector, we are able to significantly decrease the size of the detector structure while maintaining good responsivity (typically 0.1 A/W). In such a geometry the detector bandwidth is not capacitance limited, while the leakage current is reduced toward 1 nA. We also show that these PDs may be used in the drop port of a RR to monitor the propagating signal. These devices have applicability in multiplexing and potential for integration with high speed modulation functionality.
