Scientists have advanced this field by stabilizing exciton polaritons in semiconductor photonic gratings, achieving long-lived and optically configurable quantum fluids suitable for complex system simulations.Researchers from Leicester CNR Nanotec and the School of Physics at the University of Warsaw used a new generation of semiconductor photonic gratings to optically customize the composite of q...
Recently, researchers and their partners from the Fraunhofer Institute for Reliability and Microstructure (IZM) in Germany announced the successful development of a laser welding technology that can efficiently fix optical fibers onto photonic integrated circuits (PICs) without the need for adhesive bonding.This technology is developed in response to biophoton sensing technology, mainly utilizing ...
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...
Just ten years ago, fiber laser cutting machines were considered experts in thin plates. The stores quickly realized that they had to invest in them to compete, at least by reducing their instrument materials. For high-quality sheet metal cutting, CO2 laser is still the way to go. Of course, fiber lasers can cut thicker blanks, but the quality is not very good, and their speed advantage almost dis...
