OAKLAND, California : Silicon Valley chip startup Ayar Labs raised another $25 million after its latest funding round closed, as demand has increased for faster, more energy-efficient computing for artificial intelligence applications,…

Scientists have devised a way of fabricating a complex structure, previously found only in nature, to open up new ways for manipulating and controlling light. The structure, which naturally occurs in the wing scales of some species of…

As buzz grows ever louder over the future of quantum, researchers everywhere are working overtime to discover how best to unlock the promise of super-positioned, entangled, tunneling or otherwise ready-for-primetime quantum particles, the…

One of the most tedious, daunting tasks for undergraduate assistants in university research labs involves looking hours on end through a microscope at samples of material, trying to find monolayers. These two-dimensional materials -- less…

Researchers have developed new polymer materials that are ideal for making the optical links necessary to connect chip-based photonic components with board-level circuits or optical fibers. The polymers can be used to easily create…

An international team of leading scientists, headed up by Paderborn physicist Professor Klaus Jöns, has compiled a comprehensive overview of the potential, global outlook, background and frontiers of integrated photonics. The paper -- a…

Over the past several decades, researchers have moved from using electric currents to manipulating light waves in the near-infrared range for telecommunications applications such as high-speed 5G networks, biosensors on a chip, and…

Diffraction is a natural property of light beams. It allows light to bend around obstacles. Because light serves as a carrier of information, some of the distorting effects of diffraction must be mitigated for many technological…

A research team led by Prof. Kei-May LAU of the Department of Electronic and Computer Engineering at Hong Kong University of Science and Technology (HKUST) has recently developed a novel semiconductor deposition scheme and demonstrated…

Lasers, devices that emit light in one direction, with photons traveling at one specific frequency and all with the same phase (coherent), govern the way we communicate today. Although lasers are known to most people as little torches…
