Over the past decade, single-mode optical fiber has become firmly established as the preferred medium for terrestrial communications. Without the vast data capacity of these types of fiber (practical ...

Researchers have developed a microscopic 3D-printed optical device that can efficiently combine light from dozens of small semiconductor lasers into a single multimode optical fiber with very low loss ...

High-order and multiple modes in high-frequency micro/nanomechanical resonators are attractive for empowering signal processing and sensing with multi-modalities, yet many challenges remain in ...

Optical spectroscopy is a fundamental tool in numerous areas of science and technology. Much effort has focused on miniaturizing spectrometers, but thus far at the cost of spectral resolution and ...

Australian-US team says wavefront-shaping of input light lifts power threshold for SBS scattering by an order of magnitude. A narrowband laser beam shaped by a spatial light modulator excites many ...

Over the span of two projects, researchers at the University of Illinois Urbana-Champaign investigated using a propulsion concept known as multimode propulsion to get spacecraft to the Moon and ...

Company says record-breaking result will contribute towards technology to support post-5G mobile communications. Japan's KDDI Research and Sumitomo Electric Industries have announced that their ...

Expectations for devices in the rapidly expanding smartphone market segment are high. In addition to reliable voice calling, they must support data services over a range of cellular technologies (GPRS ...

The two big buzzwords of 2008—mobility and convergence—are impacting the ecosystem that serves the wireless industry in many ways. From consumers who demand to be connected wherever they are and using ...

Last time, I discussed infrastructure strategies for a multimode 802.11b/a/g environment. A combination of G/A access points provides the maximum number of nonoverlapping channels. The more channels ...
