Credit: CC0 Public Domain Researchers have developed a new approach that uses a single laser cavity to create two high-power optical frequency combs emitting high-power femtosecond pulses. The new development paves the way for portable dual-comb light sources for applications such as spectroscopy and precision distance measurement. Optical frequency combs […]

Credit: Ant Rozetsky ITMO University scientists have conducted several experiments to investigate polymeric quasicrystals that ultimately confirmed their initial theory. In the future, the use of quasicrystals may open up new possibilities for laser and sensor design. This paper was published in Advanced Optical Materials. Crystals are solids with a periodic […]

Electrically pumped surface plasmon-polariton nanolaser. Credit: Dmitry Fedyanin Researchers from the Moscow Institute of Physics and Technology and King’s College London cleared the obstacle that had prevented the creation of electrically driven nanolasers for integrated circuits. The approach, reported in a recent paper in Nanophotonics, enables coherent light source design on […]

Schematic of a laser-illuminated nano-optical probe investigating a strained nanobubble of tungsten diselenide (WSe2; green and yellow balls), a 2-dimensional semiconductor. The single layer of WSe2 is sitting on a layer of boron nitride (blue and grey balls).

This graphic depicts a stylized rendering of the quantum photonic chip and its assembly process. The bottom half of the image shows a functioning quantum micro-chiplet (QMC), which emits single-photon pulses that are routed and manipulated on a photonic integrated circuit (PIC). The top half of the image shows how […]

Tokyo Skytree is a broadcasting and observation tower in Sumida, Tokyo. It is the tallest tower in the world, reaching a height of 634 meters (2,080 ft). In another verification of the validity of Einstein’s theory of general relativity, published in Nature Photonics, scientists from the RIKEN Center for Advanced […]

A look inside the Metal Organic Vapor Phase Epitaxy (MOVPE). This machine was used to grow nanowires with hexagonal silicon-germanium shells. The emission from this hexagonal-SiGe alloy showed to be very efficient and suitable to start producing an all-silicon laser. Credit: Nando Harmsen, TU/e Breakthrough after 50 years of work […]
