Abstract

The present invention relates to a tri wavelength diffraction modulator (TWDM) and a method of tri wavelength diffraction modulation. The tri wavelength diffraction modulator includes: a stationary substrate with a bottom electrode plate formed on top of the stationary substrate; a first electrode plate comprising a first suspended beam suspended in parallel above the stationary substrate and a first connection anchored onto the stationary substrate; and a second electrode plate comprising a second suspended beam suspended in parallel above the first electrode plate and a second connection anchored onto the stationary substrate. The diffraction modulator and the method for diffraction modulation are suitable to projection system.

Description

technical field [0001] The invention relates to a three-wavelength diffraction modulator (Tri Wavelength Diffraction Modulator, TWDM) and a three-wavelength diffraction modulation method, belonging to the technical field of optical modulation equipment. Background technique [0002] Optical modulators are solid-state miniature devices that are widely used in microdisplay projection and other optical signal processing systems. An optical modulator is capable of controlling or modulating an incident beam of light in a defined spatial pattern, which is linked to the electronic input of a series of images of the device, in such a way that the intensity, phase, polarization or direction of the incident beam of light can be modulated. [0003] The two most commonly used optical modulators, especially spatial light modulators, are microelectromechanical systems (MEMS) devices arranged in a two-dimensional array to provide two-dimensional modulation of incident light, namely: Texas ...
