Abstract

Non-linear semiconductor materials coupled to Fabry-Perot (FP) microcavity are promising devices for the implementation of ultrafast and sensitive two-dimensional optical information processing systems such as optical spatial reconfigurable interconnections, coherent optical gate or optical time demultiplexing A common means of obtaining fast semiconductor modulators is to modulate the dielectric function by exploiting the presence of free photogenerated carriers which have a short lifetime However, these structures require a relatively high free-carrier density and so the high-bit-rate processing is limited by thermal problems One way of avoiding such problems would be to use no-dissipative physical effects, which although weak can be enhanced using microcavities [1] On this communication, we present an ultrafast all-optical modulator, based on the Optical Stark Effect
