- Transmissive image modulator using multi Fabry-Perot resonant modes and multi absorption modes

摘要

A transmissive image modulator capable of modulating an image over a wide bandwidth using a multi-Fabry-Perot resonance mode and a multiple absorption mode is disclosed. A transmissive image modulator comprises: a lower reflective layer; An active layer disposed on the lower reflective layer, the active layer including a plurality of quantum well layers and a plurality of barrier layers; An upper reflective layer disposed on the active layer; At least one first micro-cavity layer disposed in the lower reflective layer; And at least one second micro-cavity layer disposed in the upper reflection layer, wherein, when the resonance wavelength is?, The active layer and the at least one first and second micro-cavity layers have an integral multiple of? / 2 It may have an optical thickness.
