A fiber coupler is an optical fiber device with one or more input fibers and one or several output fibers. Light from an input fiber can appear with the power distribution potentially depending on the wavelength and polarization. Such couplers can be fabricated in different ways,for example by thermally fusing fibers so that their cores get into intimate contact.
If all involved fibers are single-mode (i.e., support only a single mode per polarization for a given wavelength), there are certain physical restrictions on the performance of thecoupler. In particular, it is not possible to combine two or more inputs of the same optical frequency into one single-polarization output without significant
