New type of femtosecond laser: used for broadband terahertz generation and nonlinear wafer detection

Optical metamaterials are an effective way to utilize their superior photon capture capabilities. Therefore, perfect absorbers can be achieved through nanoscale resonant plasmas and metamaterial structures.Metamaterial perfect absorbers (MPAs) are typically composed of periodic subwavelength metals (such as plasma superabsorbers) or dielectric resonance units. Compared with static passive physical...

In the field of optoelectronics, researchers from Busan National University in South Korea and the University of Oxford in the UK have successfully improved the signal amplification ability of CsPbBr3 perovskite nanosheets through innovative patterned waveguide methods, bringing new possibilities for the future of optoelectronics. This breakthrough not only has potential applications in fields suc...

Superlenses are nano artificial structures that can manipulate light, providing a technique that can significantly reduce the size and thickness of traditional optical components. This technology is particularly effective in the near infrared region, and has great prospects in various applications, such as LiDAR, which is called "the eye of autonomous vehicle", mini UAV and blood vessel detector.D...

Researchers at the University of Sydney combined photon filters and modulators on a single chip, enabling them to accurately detect signals on the broadband RF spectrum. This work brings photonic chips closer to one day, potentially replacing larger and more complex electronic RF chips in fiber optic networks.The Sydney team utilized stimulated Brillouin scattering technology, which involves conve...

Snapmaker has opened pre-orders for 20W and 40W laser modules, which are significant upgrades to the modules available on existing Snapmaker machines.Snapmaker says that with the 40W module installed, you will be able to cut 15 mm basswood plywood at a time at a speed of 20 mm/SEC. With 20W, you will cut 10mm at a rate of 10mm/SEC. That's a lot more than Artisan and Snapmaker 2.0 - both are comp...
