Abstract:
An optical selector comprising:a plurality of bidirectional first optical waveguides, each first optical waveguide having a plurality of first Bragg gratings that are tunable with respect to selectively defining wavelength bands of low transmissivity;N bidirectional second optical waveguides, N being a number greater than one, said second optical waveguides including generally identical configurations of M second Bragg gratings that are tunable with respect to selectively defining wavelength bands of low transmissivity;a bidirectional coupler optically coupling said first and second optical waveguides for enabling bidirectional optical transmissions between each of said first optical waveguides and each of said N second optical waveguides; andat least one Bragg grating tuner connected to independently manipulate said tunable first and second Bragg gratings.
