High-Speed Modulation Using Photonic Crystals on Digital Micromirror Devices (DMDs)
This technology integrates photonic crystals into digital micromirror devices (DMDs). The photonic crystals are incorporated on the surface of the DMD mirror in such a way as to achieve guided mode resonance, creating resonance features that are highly sensitive to changes in the angle of incidence. This increased sensitivity to angle changes minimizes...
