Optimising laser-driven electron acceleration

The interaction between lasers and matter is at the forefront of new investigations into fundamental physics as well as forming a potential bedrock for new technological innovations. One of the initiatives spearheading this ...

Natural three-dimensional nonlinear photonic crystal

Nonlinear photonic crystals (NPCs) are transparent materials that have a spatially uniform linear susceptibility, yet a periodically modulated quadratic nonlinear susceptibility. These engineered materials are used extensively ...

Creating a next-generation photonic-electronic integration circuit

Global internet is growing at a compound rate of 24% per year, reaching 3.3 zettabytes per year by 2021. High-speed optical communication is urgently needed in this ever-connected world, and to keep up with this growth, developments ...

Danish researchers develop budget optical ammonia sensor

In collaboration with the Technical University of Denmark (DTU), the Department of Engineering at Aarhus University has developed photonic sensor technology that can pave the way for a portable, reliable and, above all, inexpensive ...

Pumping a nanoparticle to lase at low power

Lasers are used in a range of everyday devices, harnessing the power of light molecules, photons, - lined up to form highly concentrated beams of light—to perform now common tasks such as scanning barcodes and removing ...

Nonlinear beam cleaning in spatiotemporally mode-locked lasers

In the last few decades, only temporal modes have been considered for mode-locked fiber lasers using single-mode fibers. Mode-locked single-mode fiber lasers offer advantages due to their high-gain doping, intrinsically single-spatial ...

Researching on-chip erbium-doped lithium niobate microcavity lasers

As a complement to silicon-based photonic chips, lithium niobate thin film (LNOI) has become a research hotspot in the field of optoelectronic integration due to its outstanding nonlinear, electro-optic, acousto-optic, piezoelectric ...

Light confinement in a 3-D space

The emerging services such as data center cloud interconnection services, ultra-bandwidth video services, and 5G mobile services stimulate the fast development of photonic integrated circuits (PIC), which can meet the increasing ...

T-ray technology reveals what's getting under your skin

A new method for analyzing the structure of skin using a type of radiation known as T-rays could help improve the diagnosis and treatment of skin conditions such as eczema, psoriasis and skin cancer.

Shining a light on nanoscale dynamics

Physicists from the University of Konstanz, Ludwig-Maximilians-Universität München (LMU Munich) and the University of Regensburg have successfully demonstrated that ultrashort electron pulses experience a quantum mechanical ...

Vibrational encounters—phonon polaritons meet molecules

Researchers from CIC nanoGUNE BRTA (San Sebastian, Spain), in collaboration with the Donostia International Physics Center (San Sebastián, Spain) and the University of Oviedo (Spain) employed a spectroscopic nanoimaging ...

Researchers use infrared light to detect molecules

Ordinary solid-state lasers, as used in laser pointers, generate light in the visible range. For many applications, however, such as the detection of molecules, radiation in the mid-infrared range is needed. Such infrared ...
