Optical Implementation Of Associative Memory: Study Of Lithium Niobate

Lithium niobate crystal has been used for storing information that can be accessed through an associative recall. This fact demonstrates the application of the crystal to the optical memory, specifically in an optical ring resonator. One Important factor that determines the recall ability is the diffraction efficiency. Particularly, this quantity is also a function of the polarization of the readout beam. The diffraction efficiency of the crystal is significant if the sufficient build-up of power in the real-time programmable ring resonator is required. This paper is concentrated on the study of the dependency of diffraction efficiency on the polarization of recall beam and the significance of orientation of c-axis of the crystal.
