Abstract:

A device may include a filter array disposed on a substrate. The filter array may include a first mirror disposed on the substrate. The filter array may include a plurality of spacers disposed on the first mirror. A first spacer, of the plurality of spacers, may be associated with a first thickness. A second spacer, of the plurality of spacers, may be associated with a second thickness that is different from the first thickness. A first channel corresponding to the first spacer and a second channel corresponding to the second spacer may be associated with a separation width of less than approximately 10 micrometers (.mu.m). The filter array may include a second mirror disposed on the plurality of spacers.
