The Hong-Ou-Mandel Effect was originally observed in 1987 by C.K. Hong, Z.Y. Ou, and L. Mandel. Their experiments found that only two of the four classically predicted outcomes were observed when two indistinguishable photons were fired at a 50 : 50 beam splitter within a very small (on the order of picoseconds) time interval. Our […]
C52: Quantum Mechanical Anti-Lasers in Optical Cavities and Waveguides
First demonstrated in 2011, Coherent Perfect Absorption (CPA) is a robust technique to achieve perfect absorption when shining a coherent light on a loss medium with no apprent reflection, behaving just like an ideal blackbody. The technique is colloquially referred to as an “anti-laser”, for it is exatly the lasing process played backwards in time. […]
