We report the characteristics of high Q factor chalcogenide ring resonators designed for sensing in the mid-infrared (MIR). The resonators consisted of an exposed Ge11.5As24Se64.5 core on a Ge11.5As24S64.5 bottom cladding and were fabricated in the racetrack coupled ring structure. Loaded Q factors at 5.2μm up to 58,000were obtained, corresponding to an intrinsic Q of 145,000 and a waveguide propagation loss of 0.84dB/cm.
我们报道了为中红外（MIR）传感设计的高Q因子硫族化物环形谐振器的特性。这些谐振器由位于Ge11.5As24S64.5底部包层上的暴露的Ge11.5As24Se64.5纤芯组成，并采用跑道耦合环形结构制造。在5.2μm处获得了高达58,000的加载Q因子，对应于145,000的本征Q和0.84dB/cm的波导传播损耗。
