摘要： A selective frequency extractor is disclosed which forwards one or more selected frequencies of a wavelength division multiplex input signal consisting of N channels to one output port and all the other frequencies to another output port. A reconfigurable frequency add and drop multiplexer is also disclosed. The input signal is divided up by a first demultiplexer and routed to a plurality of interleaved stages of optical switches for selectively feeding a plurality of input ports of a multiplexer, whose routing properties are then used for extracting one or more frequencies from the input signal or for reconfigurable frequency add and drop multiplexing.

摘要： The invention relates to a reconfigurable optical switching system for selectively coupling one or more frequencies of first and second input wavelength division multiplex signals (WDM1, WDM2) consisting of N channels to first and second output ports (O1, O2). The invention also relates to a variable and reconfigurable optical delay circuit comprising said optical switching system associated with an optical delay loop. The input frequency division multiplex optical spectra (WDM1, WDM2) are therefore divided by a first demultiplexer (Demux) to a plurality of interleaved stages of optical switches (D, C, A and B) which selectively feed a plurality of input ports (Mi) of a multiplexer (Mux), which then uses its routing properties to implement in particular the complex reconfigurable multiple 2×2 frequency switching function.

摘要： The wavelength tunable optical filter (1) comprises a resonant cavity (4) delimited by two opposite reflective elements (8, 8′) which are not wavelength selective, and a reflector (7) external to the cavity (4). The external reflector (7) exhibits transmission peaks for an integer number N of optical frequencies and the Fabry-Perot cavity (4) delimiting a phase tuning section (11) is sized so that the distance between the optical frequencies of any two resonant modes of the cavity (4) is never equal to the difference between the optical frequencies of any two transmission peaks of the external reflector (7).
