Fomation and Properties of Multiple-Tone Spatial Light Modulator using Garnet Film with In-Plane Magnetization
Journal of Magnetics, Volume 11, Number 3, 30 Sep 2006, Pages 143-146
Abstract
We attempted to fabricate a new type of magneto optic spatial light modulator (MO-SLM) for multiple-tone modulation by using in-plane magnetization. In the MO-SLM, magnetic property of magneto-optical layer was modified to be suitable for multiple-tone expression by substituting Al in Bi:YIG film. At a driving current to 28 mA in an electrode of the fabricated MO-SLM, changes in brightness of pixels were observed using a polarization microscope.
