Title:
SPATIAL LIGHT MODULATOR
Document Type and Number:
WIPO Patent Application WO/2020/125674
Kind Code:
A1
Abstract:
An optical device and an optical system, comprising a one-layered or multi-layered structure; the structure comprises an upper substrate (1), an intermediate medium layer (3), and a lower substrate (2), which are disposed in sequence; the intermediate medium layer (3) is at least one-layered; and a birefringent material (4) is filled between the upper substrate (1) and the intermediate medium layer (3) as well as between the intermediate medium layer (3) and the lower substrate (2). The optical device and the optical system may achieve phase modulation while changing the polarization direction of incident light, while also modulating the intensity and phase of the incident light, thus increasing the response speed of the spatial light modulator to modulation signals.
