摘要: A tunable optical filter for use in wavelength division multiplexing systems. The contains a plurality of reflection gratings which block all the channels incoming lightwave. An electrode or heating element is provided each grating to tune so that their bands do not coincide with desired channel thereby allowing pass through filter.
