High-Performance 1024-Pixel EO Spatial Light Modulator Using Cascaded Periodically-Poled Raman-Nath Gratings

We propose and demonstrate an electro-optic Raman-Nath spatial light modulator with a wide acceptable angle using cascaded periodically-poled gratings. The modulator has three grating stages of harmonic periods for enhancement of the extinction ratio. The modulator of 1024 pixels for practical appli...
