Light can calculate functions during propagation and interaction with structured materials, with fast speed and low energy consumption. The use of all optical neural networks for general computing requires an optical activation layer with nonlinear dependence on the input. However, existing optical nonlinear materials either have slow speeds or very weak nonlinearity at the level of natural light ...
Recently, SMART Photonics, a Dutch photonic integrated circuit manufacturer, announced a major decision to transfer its entire production capacity from 3-inch wafers to 4-inch silicon substrates, thereby expanding the production scale of photonic chips and significantly reducing chip prices.According to the company, SMART Photonics is one of the first photonic integrated circuit foundries to provi...
Recently, Laser Photonics Corporation (LPC) announced that it has partnered with Foon Technologies to receive its second order for the DefenseTech MRL (MF-1020) handheld cleaning system, which was facilitated by a distributor.The DTMF-1020 air-cooled handheld pulse laser cleaning equipment adopts dual axis technology, simplifying the maintenance process. The system will be used by the Navy Command...
OLED is located at the top and is formed by an organic layer between the contacts. Apply voltage to it, inject charge and generate light, which in turn excites organic laser. Organic lasers contain a grating that can generate feedback and diffract some of the laser out of the structure.Organic laserResearchers have created the first organic semiconductor laser to operate without the need for a sep...
Recently, a team led by Gao Chunqing and Fu Shiyao from the School of Optoelectronics at Beijing University of Technology combined optical spatial coordinate transformation with photon spin Hall effect to construct a photon angular momentum filter for the first time internationally, achieving on-demand regulation of photon spin angular momentum and orbital angular momentum.The related achievements...
