Abstract
In this paper we discuss the possibility for realizing an optical memory us ing dynamic refreshment. Via phase-correct back-coupling by means of nonlin ear optical phase-conjugation, the information stored in a photorefractive crystal is incessantly read out, transmitted into an auxiliary memory and f rom this back into the crystal again and in this way refreshed. Practical r ealizations and first results are presented. (C) 2000 Elsevier Science Ltd. All rights reserved.
