ABSTRACT:
A compact, high-performance WDM coupler which couples at least three optical fibers is presented. The coupler has the ends of first, second and third optical fibers near a first face of a collimating lens. A wavelength-dependent filter, such as a long-pass filter, a short-pass filter or a band-pass filter, is located near the opposite face of the collimating lens. The wavelength-dependent filter and the ends of the first and second optical fibers are arranged with respect to each other so that light from the first optical fiber and reflected by the wavelength-dependent filter passes into the second optical fiber. Light which passes through the wavelength-dependent filter remains collimated by the collimated lens. Reflecting elements or a second collimating lens in focus with the end(s) of one or more optical fibers can placed next to the wavelength-dependent filter and on the other side of the collimating lens to create variations of the WDM coupler for many applications.
