In this study, we propose a novel all-optical switch that is controlled by the thermo-optic effect in a silicon ring resonator with a metal cladding layer. A pump light is efficiently converted into heat through absorption by a metal layer, causing a resonant wavelength shift. The burst-switching measurement reveals a switching on/off ratio of 5.7 dB at the drop-port with a pump power of 20 mW.

金属沉积硅环谐振器中光热转换的全光开关

在这项研究中，我们提出了一种新型全光开关，该开关由具有金属包覆层的硅环形谐振器中的热光效应控制。泵浦光通过被金属层吸收而有效地转化为热量，从而导致共振波长偏移。突发开关测量显示在抽运功率为 20 mW 的分路端口处开关开/关比为 5.7 dB。
