A novel method is used to deflect the laser beam using only air. The interdisciplinary research team reported in the journal Nature Photonics that invisible gratings made solely of air not only do not suffer damage from lasers, but also retain the original quality of the beam. The researchers have applied for a patent for their method.Technology and PrinciplesThis innovative technology utilizes so...
Figure: Experimental setup.Quantum memory that relies on quantum band integration is a key component in developing quantum networks that are compatible with fiber optic communication infrastructure. Quantum engineers and information technology experts have yet to create such a high-capacity network that can form integrated multimode photonic quantum memories in communication frequency ban...
