Resonant holography.
We present a method of enhancing the diffraction efficiency of a hologram by placing it inside a resonant optical cavity. The diffraction efficiency improves on account of the multiple passes that the incident light undergoes inside the optical cavity. The resonance condition in this case turns out to involve both mirror reflectivity and the optical path length inside the cavity. Experimental results for a resonantly enhanced angle-multiplexed holographic memory and an optical three-port element are shown.
