摘要： The invention provides a multi-cavity filter, and in particular, a multi-cavity bandpass filter having a predetermined centre wavelength. The filter includes a plurality of cavities, each cavity including two partially reflecting films separated by a layer of dielectric material. The two partially reflecting layers are formed from layers of material having alternating high and low refractive indices. Each layer of dielectric material has a thickness that is an integral number of half-waves of the centre wavelength. The filter has an asymmetric structure that causes the reflected chromatic dispersion from one side of the filter to be reduced relative to the reflected chromatic dispersion from the other side.

摘要： A wavelength-tunable add/drop device for adding or dropping n channels having different center wavelengths is disclosed. A first multicavity variable optical filter for selectably operable to passing one channel while reflecting n−1 other channels depends upon a location where light is launched into an end of the multicavity optical filter. A broadband optical reflector is disposed directly adjacent to the multicavity variable optical filter and disposed between planes coincident with the first and second surfaces of the variable filter, the broadband reflector having a reflectivity that will reflect all n channels of light. Preferably, the broadband reflector is disposed distal from the bottom and top layers of the multicavity filter and is adjacent to the middle layers or near the middle of the multicavity filter layers.
