Highly efficient THz four-wave mixing in doped silicon
Abstract Third-order non-linearities are important because they allow control over light pulses in ubiquitous high-quality centro-symmetric materials like silicon and silica. Degenerate four-wave mixing provides a direct measure of the third-order non-linear sheet susceptibility χ (3) L (where L rep...
