Sentences with phrase «photon absorption»
"Photon absorption" refers to the process through which a photon, which is a tiny bundle or particle of light, is absorbed or taken in by an atom, molecule, or material. When a photon is absorbed, it transfers its energy to the absorbing particle, causing a specific reaction like exciting an electron or heating up the material. This absorption of photons plays a crucial role in various scientific applications, such as solar cells, photosynthesis, and the functioning of our eyes. Full definition
«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.

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.
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.
In the latest study, Feng's group found that not only does photon - assisted tunneling occur in the transistor laser, but that it in turn stimulates the photon absorption process within the laser cavity, making the optical switching in the device even faster and allowing for ultra-high-speed signal modulation.
Mr. Qian is currently working on using two - photon absorption to develop high density storage devices built in single crystals.
