Paper Abstract

In this paper, a novel spatial light modulator is presented. A pixel of the novel spatial modulator is turned fully OFF when all pixel ribbons form a flat reflective plane and turned ON by electrostatically deflecting alternate ribbons to produce a blazed diffraction grating. According to scalar diffraction theory, the optical performance is analyzed in details. And the influence factors on diffractive efficiency are discussed. Meanwhile, with the application of electromagnetics, electrodynamics analysis is introduced including the relation between threshold voltage and structure material characteristic. Computer simulation on the condition of different incidence light, different duty-cycle is carried on, presenting the relation between diffraction efficiency and wavelength, duty-cycle, etc. There is a promising foreground based on optimization of structure.
