Assignee: WISCONSIN ALUMNI RESEARCH FOUNDATION
Field: Audio-visual technology (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 0:
1. A resonant cavity spectrometer comprising:
a reflector;
a first dielectric spacer disposed over the reflector, the first dielectric spacer having a thickness gradient along a lateral direction;
a second dielectric spacer disposed above the first dielectric spacer, the second dielectric spacer having a thickness gradient along a lateral direction; and
a pixel array comprising a plurality of photodetectors, the photodetectors comprising photosensitive semiconductor nanomembranes, disposed between the first dielectric spacer and the second dielectric spacer, wherein the reflector, the first dielectric spacer, and the second dielectric spacer define a resonant cavity having a cavity height gradient along at least one lateral direction.
