TRANSMISSIVE IMAGE MODULATOR USING MULTI-FABRY-PEROT RESONANT MODE AND MULTI-ABSORPTION MODE, AND METHOD OF FORMING TRANSMISSIVE IMAGE MODULATOR

摘要

PROBLEM TO BE SOLVED: To provide a transmissive image modulator with multiple Fabry-Perot resonant modes and multiple absorption modes, for performing image modulation over a wide bandwidth, which is easy to manufacture and has a big transmittance difference.SOLUTION: The transmissive image modulator includes: a lower reflection layer 110; an active layer 120 disposed on the lower reflection layer, and including multiple quantum well layers and multiple barrier layers; an upper reflection layer 130 disposed on the active layer; and at least one micro-cavity layer 111, 131 disposed in at least one of the lower reflection layer and the upper reflection layer. The active layer and the at least one micro-cavity layer have thicknesses of a multiple of /2, where is a resonant wavelength.
