Scientists develop flat-topped laser beams to overcome Gaussian distribution limitations
The beam emitted by almost all laser systems follows the Angle pattern of Gaussian distribution. The Gaussian irradiance distribution means that irradiance has a smooth peak at the center point and slowly declines toward the edge. In theory, the irradiance level of a Gaussian distribution can never reach zero, which means that the distribution can expand indefinitely. This phenomenon in the laser beam results in a large amount of light energy bei...
Scientists have used 3D integration technology to bring ultra-low noise lasers without isolators to silicon photonics
After electronic integrated circuits (Eics), silicon (Si) photonics technology is expected to achieve photonic integrated circuits (PIC) with high density, advanced functions and portability. Although various silicon photonics fountifiers are rapidly developing PIC capabilities to enable mass production of modulators, photodetectors and, more recently, lasers, silicon PIC has not yet met the stringent requirements for laser noise and overall syst...
The research team describes laser direct writing of single-photon optical fiber integrated multimode storage on a communication band chip
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 bands. In a new report in Science Advances, Xu...
The laser direct writing lithography equipment market is expected to reach $160.25 million in 2029 with a compound growth rate of 5.21%
Lithography machine is the key equipment for making high precision mask plate. Using a very fine laser beam, the highly precise line pattern is drawn on the mask substrate under the control of an extremely precise automatic control system. Laser direct writing is to use a laser beam with variable intensity to implement variable dose exposure on the resist material (photoresist) on the substrate surface, and form the required relief contour...
Scientists uncover the HPC potential of advances in communications and global laser light sources
Thanks to the advent of high performance computing (HPC) for global laser light sources, the optical communications world is on the verge of major change. This revolutionary technology will redefine the way we transmit and receive data, bringing unprecedented speed and efficiency. Optical communication, which uses light to transmit information, has been a cornerstone of our digital world for decades. They form the backbone of our Internet, enabl...
Medium-long wavelength infrared quantum cascade laser of MOCVD on silicon
Us researchers report 8.1 μm wavelength quantum cascade laser (QCL) grown on silicon (Si) by MOCVD [S. Xu et al., Applications. Physics Letters, v123, p031110, 2023]. "There are no previous reports of QCL growth on silicon substrates by metal-organic chemical vapor deposition (MOCVD)," commented the team from the University of Wisconsin-Madison, the University of Illinois at Urbana-Champaign and MicroLink Devices Inc. This integration o...
Researchers have developed a quantum cascade laser in Italy
The first all-Italian quantum cascade laser was born at the National Research Center in Pisa. The protagonists of this milestone are two researchers from the Nanoscience Institute, Lucia Sorba and Miriam Serena Vitiello, who together with their research team designed and developed this innovative device.In fact, quantum cascade lasers have unique potential for detecting gases and other molecules, and can be used in environmental monitoring, indus...
