When will the protruding rear camera on smartphones become obsolete? The implementation of a metasurface, which completely disregards the properties of light, promises to reduce the thickness of a camera lens to 1/10,000 ...
Quantum emission is pivotal to realizing photonic quantum technologies. Solid-state single photon emitters (SPEs), such as hexagonal boron nitride (hBN) defects, operate at room temperature. They are highly desirable due ...
A team of materials scientists and engineers at Stanford University, working with a colleague from ETH Zürich and another from Washington University in St. Louis, has developed a biochip that can be used to screen thousands ...
Using conventional testing techniques, it can be challenging—sometimes impossible—to detect harmful contaminants such as nano-plastics, air pollutants and microbes in living organisms and natural materials. These contaminants ...
A cutting-edge practice by two Vanderbilt researchers that enhances light in nanoscale structures could help in the detection of diseases like cancer.
Precise control of light is a crucial requirement in optical imaging, sensing, and communication. Traditional lenses employed for the purpose have limitations, necessitating more precise and compact solutions. To address ...
Pulsed laser scanning lidar is a core technology for autonomous driving and robotic mobility. Herein, a directional light pulse is backscattered by a reflective object and the elapsed time between emission and detection of ...
Electromagnetic (EM) wave front modulation has important significance in both scientific research and industrial applications. However, conventional dielectric materials have limited choices of dielectric constants. In addition, ...
Researchers at the National Institute of Standards and Technology (NIST) have devised a photonic circuit on a chip that transforms a single incoming beam of laser light into a panoply of new beams, each with a host of different ...
Optical devices and materials allow scientists and engineers to harness light for research and real-world applications, like sensing and microscopy. Federico Capasso's group at the Harvard John A. Paulson School of Engineering ...
