Description
The terahertz (THz) region lies in between of the RF and optical spectral regions and is expected to become a part of novel wireless links due to its high bandwidth and safety. Therefore, a refined control over THz radiation is required.
We investigate the influence of spatially controlled, near-infrared induced charge carriers in high-resistivity silicon on a collimated THz beam. Our results indicate that the refractive index is significantly modulated. This spatially controlled modulation is especially interesting regarding phase-modulation, which may pave the way for beam-steered wireless THz links.
