论文摘要
缺陷中心是波导集成硅光源的有希望的候选者。我们展示了微孔和波导偶联的光致发光，来自硅W〜中心。麦粒发光测量表明，与谐振器模式的波长优先耦合到相邻的波导。测量至少5,300的质量因素，自由光谱范围与预期非常匹配。 W〜中心声子侧带可用作低温硅光子平台上基于范围的波导设备的光谱诊断。
Defect centers are promising candidates for waveguide-integrated silicon light sources. We demonstrate microresonator- and waveguide-coupled photoluminescence from silicon W~centers. Microphotoluminescence measurements indicate wavelengths on-resonance with resonator modes are preferentially coupled to an adjacent waveguide. Quality factors of at least 5,300 are measured, and free spectral ranges closely match expectation. The W~center phonon sideband can be used as a spectral diagnostic for a broader range waveguide-based devices on cryogenic silicon photonic platforms.
