Researchers create ultralow-loss silicon nitride integrated photonic circuits

Scientists from EPFL have developed ultralow-loss silicon nitride integrated circuits (ICs). ICs of this sort are critical for photonic devices such as chip-scale frequency combs, narrow-linewidth lasers, coherent lidar, and neuro-morphic computing, among other uses. This type of IC can encode information into light to be transmitted through optical fibers and is described as a core component of optical communications. … Continue reading
