Abstract
A device is provided for demultiplexing a DWDM composite light signal into distinct signal channels or frequencies. The device includes a plurality of resonators, which each acts to slice an incoming signal into two equal parts. The free spectral range characteristics (FSR) of the resonators are successively increased by an even multiple to achieve the slicing effect. As a result, the resonators of the subject invention can be formed with relatively low finesse values because of the slicing effect.
