Abstract:
Narrowband light filters, and methods of manufacturing such light filters, are provided. A narrowband light filter may include at least two electrically conductive bodies, an electrically conductive thin film layer disposed between the at least two electrically conductive bodies, at least one protective oxide layer disposed on the thin film layer and electrically conductive bodies, and at least one slit disposed through the electrically conductive thin layer. In various embodiments, the electrically conductive bodies give the narrowband light filter a mirrored structure in exemplary embodiments of the invention. The narrowband filters may also include one or more slits. Multiple slits may be configured to make the narrowband filtration polarization-independent. A plurality of narrowband light filters may be configured into pixel arrays. Pixel arrays may also be used in multispectral or hyperspectral imaging apparatus and techniques.

Claim (Index 19):
A method of fabricating a narrowband light filter comprising:\n preparing a substrate formed of a dielectric material; depositing a resist material onto the substrate and patterning the resist material such that regions corresponding to at least two holes and a raised region disposed therebetween are mapped onto the substrate; depositing a mask onto the resist material and substrate, wherein at least a first portion of the mask is disposed directly onto the substrate, and wherein the first portion corresponds to the raised region; removing the resist material and etching the substrate, where at least a portion of the substrate is protected by the mask from the etching, and wherein the protected portion corresponds to the raised region and the etched portion corresponds to the at least two holes; removing the mask and depositing a protective oxide layer onto the substrate; depositing an electrically conductive layer atop the substrate such that the at least two holes are filled to form at least two electrically conductive bodies, and wherein the raised region forms a thin film layer disposed therebetween; pressing and thinning the at least one electrically conductive layer to reduce the thickness of at least the thin film layer; milling at least one slit through the thin film layer to expose a portion of the substrate; and depositing an additional layer of the dielectric material onto the exposed substrate and thinned electrically conductive such that the electrically conductive thin film and electrically conductive bodies are disposed between the substrate and additional layer of the dielectric material; and wherein the electrically conductive bodies and slit are configured in a relative geometry such that a resonance is created in electromagnetic radiation incident thereon such that only electromagnetic radiation of a specific spectral band is passed through the at least one slit.
