Definition of «photon absorption»

Photon absorption is a process in which photons (particles of light) are absorbed by an atom or molecule, causing it to become excited and transition from its ground state to a higher energy level. This can lead to chemical reactions, changes in the physical properties of materials, or other effects depending on the specific circumstances.

«The inefficiencies in highly nonlinear photonic devices are overcome here, by photonic device engineering for maximum nonlinearity, while still maintaining a sufficiently large bandgap to eliminate two - photon absorption at the telecommunications wavelength. (sciencedaily.com)
Piro, N., Rohde, F., Schuck, C., Almendros, M., Huwer, J., Ghosh, J., Haase, A., Hennrich, M., Dubin, F. & Eschner, J. (2010), Heralded single - photon absorption by a single atom. (r.unitn.it)
We will pursue a hybrid approach, exploiting the strong single - and two - photon absorption possible in the gas - phase of rubidium atoms, together with integrated - photonics, to achieve strong interactions between photons and atoms, and use these interactions to achieve efficient quantum memories, efficient photon detectors, and reliable entangling gates.
