Abstract

We are actually studying the problem of interconnecting a Gaussian beam with a 2-D optical logic gate array. The optical logic devices are reflective bistable (non-linear) Fabry-Perot etalons. The Gaussian beam is either a high power laser operating as bias power supply (illumination of all the logic gates required) or a low power laser operating as logic signal (illumination of a small subset of the logic gates reqjiired). We decide in favour of a freespe, space-variant, diffrtive optical element (DOE). The DOE is a kinoform (phase encoded phase hologram), synthesized with a modified iterative phase-retrieval algorithm (IPR) applied in the Fresnel diffrtion regime. IPR offers the possibility to solve the general problem of beamshaping and to create non regular light pau&ns. It is a usefull algorithm in the design of space-variant interconnection systems.
