Webb11 apr. 2024 · At an operating wavelength of 7.70 μm, the slow-light enhancement factor of the designed waveguide gas sensor can reach 6.1516 by introducing the slow-light effect and carefully optimizing structural parameters. When the methane is treated as the target gas, the sensitivity, and limit of detection are 19.0341 and 0.18524 ppm, respectively. Webb14 juli 2024 · Slow light in topological valley photonic crystal structures offers possibilities to enhance light-matter interaction. We report a topological cavity based on slow-light topological edge modes for broadband Purcell enhancement.
WebbThe doubly periodic Si photonic crystal waveguide operates as a nonmechanical beam-steering device that can be applied in light detection and ranging. In this Letter, we develop and describe a prism lens that collimates a fan-shaped beam, emitted from the waveguide independent of the steering angle.
