Applied optics

Enhancing spatiotemporal light modulators

The free-carrier dispersion effect with photo-excited free carriers provides all-optical control of the resonance of photonic crystal microcavities. Using this technique, a spatial light modulator comprising optically addressed cavity arrays has been developed for high-efficiency, high-bandwidth spatiotemporal modulation of light.
