All-Dielectric Meta-lens Designed for Photoconductive Terahertz Antennas

All-Dielectric Meta-lens Designed for Photoconductive Terahertz Antennas

We present an all-dielectric meta-lens designed to collimate terahertz waves emitted from a terahertz antenna. The meta-lens is not only thinner than a conventional bulk silicon lens, but also promises to eliminate the use of parabolic mirrors in a terahertz time-domain spectroscopy system. A system...
