Abstract

This paper discusses the development of an optically addressed smart pixel spatial light modulator (SLM). The term 'smart pixel' refers to the ability to modulate the phase of a read beam with greater than eight phase levels. The modulation is a function of the output of four photoactive sites per pixel. In this design the four photoactive sights surround a modulator element and are addressed by four independent write beams. The modulator is controlled by the output of a circuit connected to the photodetectors. A novel addressing scheme which utilizes diffractive microlens arrays is also presented.
