Non-linear effects in coupled optical microcavities

Scientists from the Faculty of Physics of the University of Warsaw have demonstrated exciton-polariton lasing and parametric scattering of exciton-polaritons in a system of coupled optical microcavities. The results have ...

Novel method for fast 3D microscopy

In the past, many discoveries have been made because better, more accurate measurement methods have become available, making it possible to obtain data from previously unexplored phenomena. For example, high-resolution microscopy ...

Optical innovation could calm the jitters of high-power lasers

The Berkeley Lab Laser Accelerator (BELLA) Center at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) has developed and tested an innovative optical system to precisely measure and control the ...

Researchers create powerful quantum source with meta-lens array

Researchers for the first time have demonstrated a quantum light source based on a meta-lens array. The approach offers a promising platform for both high-dimensional photon entanglement and the coherent control of multiple ...

Cascaded metasurfaces for dynamic control of THz wavefronts

Electromagnetic (EM) waves in the terahertz (THz) regime contribute to important applications in communications, security imaging, and bio- and chemical sensing. Such wide applicability has resulted in significant technological ...

A new theory to explain the transparency of metallic oxides

The electrons of some metal oxides, due to their large effective mass when coupled with the ionic lattice of the material, cannot follow the electric field of light and allow it to pass through the material. Transparent and ...

Antimatter from laser pincers

In the depths of space, there are celestial bodies where extreme conditions prevail: Rapidly rotating neutron stars generate super-strong magnetic fields. And black holes, with their enormous gravitational pull, can cause ...

An X-ray vision-like camera to rapidly retrieve 3D images

It's not exactly X-ray vision, but it's close. In research published in the journal Optica, University of California, Irvine researchers describe a new type of camera technology that, when aimed at an object, can rapidly ...

Nanostructures enable record high-harmonic generation

Cornell researchers have developed nanostructures that enable record-breaking conversion of laser pulses into high-harmonic generation, paving the way for new scientific tools for high-resolution imaging and studying physical ...
