Abstract: The present invention relates to a method and devices for multiplexing and demultiplexing optical signals. The present invention relates to a method and devices for integrating the multiplexer and demultiplexer functionality with the switch array. The wavelength switchable optical filter comprises an optical waveguide having a grating along a section thereof, the grating comprising a pre-selected number of spaced sub-gratings with each sub-grating have a sub-grating period, the grating has a spectral response characterized by a pre-selected number of spaced band-pass windows spanning a pre-selected wavelength range. The optical filter includes modifying means connected to the optical waveguide for modifying the sub-grating period, refractive index or a combination thereof for selectively opening or closing each of said band pass windows independently of all the other band pass windows.
