We examine some of the problems of theory and experiment that are limiting our understanding of photon absorption and photon scattering. Much of what we know and don't know is signified via simple models, whether (i) in semi-classical non-relativistic dipole radiation of the hydrogen atom, ...
With short current pulses, the output power of semiconductor lasers is limited by non-thermal internal loss mechanisms. Two-photon absorption (TPA) was recently proposed as dominating photon loss process. We investigate this claim by advanced numerical laser simulation that includes all relevant mechani...

This is opening up exciting avenues in optoelectronics, optical communication, solar energy harvesting, and other areas of study. Nanophotonics, however, has only emerged as a distinct discipline in the last two decades, fueled by an explosion in the development of novel metallic, dielectric, and ...

aAnother advantage of QDs is their highly efficient two-photon absorption which can be useful for three dimensional in vivo two-photon microscopy, an area that is rapidly developing biological and medical applications of QDs require water- soluble or water dispersed, 另一好处 QDs 是 他们高度 高效...
What is pulsed laser deposition? What are its applications? What is molecular emission and absorption? What is more dangerous, a radioactive material with a short half-time or a long one? Name two solid materials having very low linear expansivity. ...
Photonics is the study of light and other types of radiant energy whose quantum unit is the photon. The impact of photonics on research, technology, n
Fluorescence in fluorophores happens when a photon is absorbed and is then re-emitted as another photon, usually of lower energy. This process happens through the transition of electrons between energy levels.Contents How Does A Fluorophore Work? Common Fluorophores Fluorophore Structures Quantum dots ...
The assumption is that preparing a Bell state amounts to sharing information between two parties, which is then carried away by conservation, like angular momentum is, or polarization, etc. A photon like any other fundamental particle possesses a wavy nature and, in fact, a classical beam too...
