Photomixing in resonant laser-assisted field emission - a new technique for wide-band-tunable terahertz sources

When optical radiation is focused on a nanoscale field emitter tip, the potential and emitted current follows each cycle of the radiation field. Nonlinearity causes mixing of the optical radiation from two lasers so that current oscillations from dc to over 500 THz can be created at the tip. Several...
