Electrically and Optically Addressable Spatial Light Modulators Based on n-i-p-i Doping Superlattices

Abstract

In this paper three different versions of n-i-p-i based spatial light modulators will be discussed: 1) optically addressed modulators, based on the large non-linear absorption changes, 2) electrically addressed modulators with largely improved performance characteristics, and 3) optically addressed "smart modulators", consisting of a combination of fast detectors with gain with electro-optical modulators.
