Abstract

We describe in generic terms a class of associative memory that is based on (1) an oscillating message-bearing optical mode in a resonator containing a multimessage hologram, (2) image-selective (discriminatory) amplification of the desired picture in a photorefractive crystal, and (3) phase-conjugate reflection.

A phase-conjugate reflector compensates for distortion caused by an image field, thus permitting a message-bearing oscillation inside an optical resonator.

Fig. 2
Fig. 2

(a) Information recorded on a fixed hologram Δn. Ei is the beam carrying the information, and Eio is the reference beam. The angle between Eio(r) and Ei(r) is sufficiently large to prevent spillover of information in the memory application into the zero-order mode. (See text discussion in connection with Fig. 2.) (b) A scheme for an optical associative memory: PCM’s, the phase-conjugate mirrors; BS’s, beam splitters; Δn, the prerecorded hologram; Ei′(r), the pumping beam carrying partial information; Ei(r), one of the oscillation modes of the resonator, which is excited preferentially by Ei′(r)
