1. An apparatus comprising:
a first optical component having a plurality of first parallel conductors with a first spacing pattern, the plurality of first parallel conductors aligned in a plane perpendicular to an axis;
a second optical component having a plurality of second parallel conductors with a second spacing pattern, the plurality of second parallel conductors aligned in a plane perpendicular to the axis; and
at least one thin film dielectric layer including a refractive index change (RIC) material disposed between and in contact with the plurality of first parallel conductors and the plurality of second parallel conductors,
wherein the second spacing pattern is angularly offset from the first spacing pattern by an angular offset, and
the first optical component and the second optical component and the at least one thin film dielectric layer form an antenna array configured to detect one or more predetermined infrared wavelengths based on at least one of the first spacing pattern and the second spacing pattern and the angular offset.
