We demonstrate the design, fabrication, and characterization of single-mode low-loss waveguides for mid-infrared (MIR) wavelengths. Planar waveguide structures were fabricated from multilayer thin films of arsenic-based chalcogenide glasses followed by the creation of channel waveguides by using the photodarkening effect. Propagation losses as low as 0.5 dB/cm were measured for a quantum cascade laser end-fire coupled into the waveguides. This is a first step toward the design and fabrication of integrated optical components for MIR applications.
我们展示了用于中红外（MIR）波长的单模低损耗波导的设计、制造和特性。平面波导结构由基于砷的硫族化物玻璃的多层薄膜制成，然后利用光暗化效应创建通道波导。对于耦合到波导中的量子级联激光器，测得的传播损耗低至0.5 dB/cm。这是迈向用于中红外应用的集成光学组件设计和制造的第一步。
