Transmissive image modulator using multi-fabry-perot resonant mode and multi-absorption mode

摘要

A transmissive image modulator for allowing image modulation over a wide bandwidth with multiple Fabry-Perot resonant modes and multiple absorption modes is provided. The transmissive image modulator includes a lower reflection layer; an active layer disposed on the lower reflection layer, including multiple quantum well layers and multiple barrier layers; an upper reflection layer disposed on the active layer; and at least one micro-cavity layer disposed in at least one of the lower and 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.
