High-Efficiency Silicon THz Modulator Using Optically Injected Carriers

Ultrafast and low-power terahertz wave modulator based on organic photonic crystal

THz optics has experienced a tremendous increase in interest among the scientific community as
better THz sources and detection schemes are discovered. With recent studies in THz modulation
experiment using optically excited Si opens a new possibility in constructing THz optics using an
optically controlled THz SLM. Thus, various patterns, such as zone lenses, could be optically
constructed and tuned in real time for used in THz beam correction. For example, optically
constructed Fresnel zone lenses on high-resistivity Si can be actively tuned for focal length and
chromatic aberration, which are just some possible applications of this methodology. In this paper,
we will present results for an optically controlled single pixeled THz semiconductor SLM for use as
a modulator and discuss extensions to applications in zone lenses, diffraction gratings, and other
optical components.
