SURFACE COATING FOR OPTICAL EMITTER COMPONENTS

In some implementations, an optical component includes an optical medium, the optical medium having a surface, wherein the surface includes one or more hydroxyl group terminations; and a surface layer chemically bonded to the optical medium, such that the surface layer has a thickness of less than 10 nanometers and is a hydrophobic surface, the surface layer including at least one of: a hexamethyldisilazane material, a polysiloxane material, a polydimethylsiloxane material, a fluoro-polymer material, an organosilicon material, or an organofluorine material.
