Abstract:
1. An electronically tunable Fabry-Perot interferometer, comprising a substrate including a portion defining an optical area; a first mirror structure on the substrate; a second, movable mirror structure, whereby the first and second mirror structures define respective first and second mirrors which are substantially parallel to each other, and each of the first and second mirrors extend along the optical area; a Fabry-Perot cavity between the first and second mirrors; electrodes for electrical control of the distance between the mirrors; at least one mirror including oppositely disposed mirror layers with an intermediate a gap between the oppositely disposed mirror layers, the gap defining an intermediate mirror layer between the oppositely disposed mirror layers; and, a plurality of necks extending between the oppositely disposed mirror layers, in the intermediate mirror layer, the necks for maintaining a constant width of the gap defining the intermediate mirror layer, the necks dimensioned to minimize attenuation of the interferometer.
