Abstract

Defect centers are promising candidates for waveguide-integrated silicon light sources. We demonstrate microresonator- and waveguide-coupled photoluminescence from silicon W centers. Observations indicate that wavelengths that are on-resonance with resonator modes are preferentially coupled to an evanescently coupled waveguide. We introduce an offset collection circuit and method to differentiate waveguide-coupled emission from free-space-coupled emission. These techniques could play a major role in the development of active and passive waveguide-based devices on cryogenic silicon photonic platforms. Further research on W center-resonator coupling could yield a variety of compelling all-silicon active devices.
