Multiplexed holographic Fabry-Perot étalons

Abstract

We discuss a multiplexed holographic Fabry-Perot étalon that includes a multiplexed hologram in a novel holographic Fabry-Perot étalon. Two unique advantages can be achieved by using the multiplexed holographic Fabry-Perot étalon: coherently coupled fabrication of holographic Fabry-Perot mirrors significantly reduces the need to have the nearly flat surfaces typically required in conventional Fabry-Perot etalons, and the angular-wavelength multiplexing capability of a multiplexed hologram can be added to the tunable narrow-band filtering capability of Fabry-Perot étalons. Several types of multiplexed holographic Fabry-Perot étalon are experimentally demonstrated.

Enhanced diffraction of light in GaAs microcavities

“…Several studies have been made of a geometry where two gratings surround a cavity, i.e., the inverse of our geometry [4]. One goal has been to replace expensive high quality mirrors by low quality substrates incorporating holographic correction elements [5,6]. Other studies have considered the geometry which interests us, i.e., the grating within a cavity.…”
