Patent

CA 2344541

Methods and devices are provided for optical demultiplexing and optical multiplexing. An optical wavelength demultiplexer adapted to perform wavelength demultiplexing of an input optical signal containing a plurality of wavelengths is provided. A tuneable filter in combination with a device with a required free spectral range results in a tuneable demultiplexer arrangement which eliminates the need to inventory large numbers of different demultiplexers. Similarly, tuneable lasers in combination with a device with a required free spectral range result in a tuneable multiplexer arrangement.
