Two photon polymerization is a potential method for nanofabrication of integrated nanomaterials based on femtosecond laser technology. The challenges faced in the field of 3D nanoprinting include slow layer by layer printing speed and limited material selection due to laser material interactions.In a new report in Progress in Science, Chenqi Yi and a team of scientists in the fields of technical s...
Pierre Agostini, Ferenc Krausz, and Anne L'Huillier won the award for their ultra short optical pulses, which made close research on electrons possible.Ferenc Klaus, Anne Lullier, and Pierre Agostini (from left to right)Image sources: BBVA Foundation, Kenneth Ruona/Lund University, Ohio State UniversityThis year's Nobel Prize in Physics was awarded to three physicists - Pierre Agostini of Ohio St...
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...
The optical properties of photonic crystals are closely related to their lattice constants, which are usually required to be in the same order of magnitude as the operating wavelength. In a crystal material, the photonic crystal structure is formed by the periodic arrangement in space of units whose dielectric constant is different from that of the crystal itself, and whose lattice constant depend...
In the era of the Internet of Things, visual image sensors, as key devices in the intelligent society, are embedded in various devices such as mobile communication terminals, smart wearable devices, automobiles, and industrial machines. With the continuous expansion of applications, higher requirements have been put forward for the system power consumption, response speed, safety performance, and ...
