Scientists have developed a microdroplet 3-D laser system in which laser light shines forth in all directions from dye molecules lodged within spherical drops of helical molecules dispersed in a ...

Researchers in the US say they have succeeded in tuning the wavelength of light emitted by a tiny laser made from plasmonic nanocavity arrays. The plasmon laser, which consists of arrays of gold ...

(Nanowerk Spotlight) Plasmon lasers are promising nanoscale coherent sources of optical fields because they support ultra-small sizes and show ultra-fast dynamics. They can make possible ...

How can tunable lasers contribute to society? This is what a recent study published in Optica hopes to address as an international team of researchers have developed a novel tunable semiconductor ...

Tunable laser sources (TLS) can be used by researchers to access a wide range of wavelengths. As a result tuneable light sources are used frequently for the determination of wavelength dependent ...

This article describes an overview of recent developments in fabrication and uses of self-assembled photonic crystals (PCs) of organic and polymer materials, such as chiral liquid crystals (CLCs) and ...

The optical networking industry experienced exponential growth from 1996 to 2000, during which time a record amount of inventory was created by bullish organizations embracing the advanced ...

WASHINGTON, D.C., Sept. 19, 2017 -- Whispering gallery mode (WGM) resonators are used to make tiny micro-lasers, sensors, switches, routers and other devices. These tiny structures rely on a ...

Researchers at the University of Tsukuba, Japan, have developed a tunable laser based on liquid droplets that can be inkjet-printed, and have a color that changes based on the shape, which may lead to ...

Whispering gallery mode resonators rely on a phenomenon similar to an effect observed in circular galleries, and the same phenomenon applies to light. When light is stored in ring-shaped or spherical ...
