WebJan 17, 2024 · To resolve the light-loss problems, the researchers added a shallow-etched grating (10 nm deep and 200 nm wide) to the silicon LSPCW, to improve the upper emission intensity. They also designed a bespoke prism lens for the setup that converts the steering angle in the desired direction.
