On a Possibility of Wavelength-Domain-Multiplication Memory Using Quantum Boxes

Abstract

A new use of quantum boxes for wavelength-domain-multiplication optical memory applications is proposed. Persistent spectral-hole burning mechanism based on photo-creation of electron-hole pairs and their spatial separation by carrier tunneling is described. We discuss the feasibility of its application to optical data storage with emphasis on the memory duration and the multiplexing factor, that is, the possible number of bits stored in a laser-beam spot following the discussion by Moerner and Levenson.
