TERAHERTZ OPTICS

Giant multiphoton absorption in silicon

Nature Photonicsvolume 12pages125126 (2018) | Download Citation

With the availability of high-intensity terahertz free-electron lasers, surprisingly large multiphoton absorptions in a phosphorus atom doped in a silicon crystal have been obtained, providing the possibility of a hydrogen-like system in silicon photonics and quantum information devices.
