Open AccessHighly efficient THz four-wave mixing in doped silicon
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 dire...

Open AccessGiant non-linear susceptibility of hydrogenic donors in silicon and germanium
Implicit summation is a technique for the conversion of sums over intermediate states in multiphoton absorption and the high-order susceptibility in hydrogen into simple integrals. Here, we derive the equivale...
