Novel mode filter for use with cladded-glass and liquid-core optical waveguides
W.A.Gambling, J.P.Dakin, D.N.Payne and H.R.D.Sunak
Two methods of filtering off high-order modes in multimode fibres are proposed. One uses a periodic sequence of apertures and the other involves continuous coupling. In this way, it may he possible to achieve bandwidths approaching 100 MHz over kilometre lengths.
