AlGalnN laser diode technology for GHz high-speed visible light communication through plastic optical fiber and water

摘要

AlGalnN ridge waveguide laser diodes are fabricated to achieve single-mode operation with optical powers up to 100 mW at ～420 nm for visible free-space, underwater, and plastic optical fiber communication. We report high-frequency operation of AIGalnN laser diodes with data transmission up to 2.5 GHz for free-space and underwater communication and up to 1.38 GHz through 10 m of plastic optical fiber.
