Spatial light modulators (SIMs) are key components of optical correlator, optical computer and holographic data storage. Various types of reusable modern SIMs with two-dimensional arrays of pixels have been intensively developed over the past three decades. Of these, magneto-optic spatial light modulators (MOSIMs) have the advantages of high switching speed, robustness, nonvolatility, and radioactive resistance. It took the advantage of the nonreciprocity of the Faraday effect, used thinner garnet film, and had a high resolution with narrower pixel gaps. But it still needed the difficult fabrication processes physically isolating the pixels and a rather high drive current to produce a magnetic field high enough to nucleate pixels. In this study, we show novel method for making the compact pixels of the MOSIM. The novel method is the Combinatory use of the effect reduced the magnetization of pixel areas at LPE garnet film by local annealing and the effect of metallization stress on magnetic domain walls. The MOSIMs using this method may be fast and reliable, provide an image of clarity and improved resolution and consume relatively low amounts of power.
