  • Method and apparatus for an optical filter
    Patent number: 6694066
    Abstract: The present invention provides optical filters that can be used in a range of telecommunications applications including optical multiplexers/demultiplexers, optical routers, and optical gain scalers. The optical filter is modular, using two or more couplers with a pair of delay paths between each pair of couplers in a sequence to generate a range of optical filter functions. The desired filter profile/function is obtained by proper selection of the coupling ratio for each coupler and by the length of each pair of delay paths. The couplers may be implemented as polarization or intensity beam splitters positioned along the optical path. Each coupler couples in controllable amounts, one or two inputs with the corresponding pair of delay paths.
