Abstract:
A method of fabricating a tuneable wavelength selective optical filter including a plurality of at least partially mutually coupled optical resonators in which a resonant wavelength of each resonator is independently tuneable, the method comprising the steps of:a) forming a series of layers on a substrate, the layers forming mirror assemblies and spacer layers therebetween; b) defining features in the layers corresponding to suspended reflectors and associated compliant support arms; c) processing the substrate and its associated layers by etching processes to generate the mirror assemblies and optical cavities therebetween where the spacer layers are present; d) defining and generating features on the assemblies operable to actuate the mirror assemblies relative to one another; and e) mounting the filter in a carrier and making electrical connection to the filter.
