a When photon-pair generation is probabilistic, a two-photon interference measurement between A2 and B1 alone cannot distinguish successful events from unsuccessful ones. Therefore, additional ...

BBO crystal (Beta barium borate crystal) is a nonlinear optical crystal which combines a number of unique features.Wide transparency and phase matching ranges, large nonlinear coefficient, high damage ...

A team of Chinese researchers used a novel theory to invent a new type of ultrathin optical crystal with high energy efficiency, laying the foundation for next-generation laser technology. Prof. Wang ...

Optical cavities, also known as optical resonators, are structures that confine light within a small volume by utilizing highly reflective surfaces. These cavities allow light to circulate or bounce ...
