AR Coatings for Optical Fibers

April 1, 2011

Laser Components (Hudson, NH) offers both assembled cables, including coated fibers, and job coatings on fibers supplied by the customer. They also offer anti-reflection coatings, which significantly reduce coupling losses when high power has to be transmitted across optical fibers using a laser. The company can process all types of fibers, from fused silica fibers (SM and MM) to sapphire fibers. It is important that all materials used, for example, in buffers, be suitable for vacuum environments. The following AR coatings are available on a standard basis for optical fibers: single AR coatings for one wavelength (e.g. 808nm); dual AR coatings for two wavelengths (e.g. 808 and 980nm); and broadband AR coatings for a wide wavelength range (e.g. 460-700nm).
