Review discusses using nonlinear optics with structured light

Light, like cloth, can be tailored by weaving and stitching a pattern into the fabric of light itself. This structured light enables us to access, harness, and exploit all of light's degrees of freedom, allowing us to see smaller in imaging, focus tighter in...

Light traveling in a distorting medium can appear undistorted

A team led by researchers at the University of the Witwatersrand in Johannesburg, South Africa, with collaborators from the University of Pretoria (South Africa), Mexico, and Scotland, has made a new discovery about how light behaves in complex media, which distorts light significantly. They...

Observation of the branched flow of spatially incoherent light in dish soap

Technion-Israel Institute of Technology researchers have conducted the first experimental observation of the branched flow of spatially incoherent light by using liquid dish soap. The study has been published in the journal Physical Review X. Scientists described their experiments involving shining light on 2D samples of...

Engineering quantum states in solids using light

POSTECH researchers have developed a platform. It can control the properties of solid materials with light and measure them. Scientists recognised for developing a platform to control and measure the properties of materials in various ways with light. The study was published in the journal...

New optical tweezers can control luminescent colour using light pressure

One big stumbling block in the field of photonics is that of colour control. To control colour that is the wavelength of light emission, scientists would have to alter the chemical structure of the emitter or the concentration of the solvent. All of it...

Black hole “make a meal” of a star decades ago

Our Milky Way and every other galaxy have a massive black hole in its centre. The gravity of the black hole influences the stars around it. The stars orbit around the black hole without incident. Sometimes a star will wander a little too close...
