“The back-side of the device was polished to a 45-degree chamfer in order to refract the intraband beam which was incident on the back of the device,” said the researchers. The scientists ...

Module 1 will cover the quantum cascade laser, a laser design based on intersub-band transitions, that enables very long wavelength lasers. It will also talk about lasers that operate on intraband ...

This Perspective surveys the role of thermal nonlinearity in figures of merit through a multiscale physical understanding to advance heat harvesting technologies beyond linear processes, focusing ...

Optical physics is the study of the fundamental properties of light and its interaction with matter. This includes classical optical phenomena such as reflection, refraction, diffraction and ...
