Mid-Infrared Slow Light Engineered One-Dimensional Grating Waveguide

The design, fabrication and characterization of one-dimensional (1D) grating waveguide as slow light structure working in mid-infrared region are demonstrated for the first time. The effects of various structural parameters on slow light properties are systematically investigated through simulation and experiment, providing solid guidance on slow light engineering in 1D grating waveguide.
