title: Biconical fibers as mode and wavelength filters.
abstract: Mode and wavelength filtering characteristics of biconical fibers are examined. A model is considered which simulates the propagation conditions in a bicone made in a slightly overmoded fiber when illuminated at two different wavelengths. The possibility of wavelength selective coupling is evident in view of different applications.
