The fundamental rotation of micro and nano-objects is crucial for the functionality of micro and nanorobotics, as well as three-dimensional imaging and lab-on-a-chip systems. These optical rotation methods can function fuel-free ...
Topological photonics is a rapidly evolving area of research that focuses on the design of photonic lattices where the behavior of light is inspired from the physics of topological insulators. While most studies in this area ...
Could a laser send a spacecraft to Mars? That's a proposed mission from a group at McGill University, designed to meet a solicitation from NASA. The laser, a 10-meter wide array on Earth, would heat hydrogen plasma in a chamber ...
Over the past few years, physicists and engineers worldwide have developed a growing number of advanced optical technologies and photonic devices, which can be used to emit, detect or manipulate light. The ability to easily ...
Rydberg atoms, which are atoms in a highly excited state, have several unique and advantageous properties, including a particularly long lifetime and large sensitivities to external fields. These properties make them valuable ...
Researchers at CNRS, Université Paris-Saclay in France have recently demonstrated the 3-D trapping of atoms in a Rydberg state inside holographic optical bottle beam traps. Their demonstration, outlined in a paper published ...
New photonic tools for medical imaging can be used to understand the nonlinear behavior of laser light in human blood for theranostic applications. When light enters biological fluids it is quickly scattered, however, some ...
Physicists have proposed an entirely new way to test the quantum superposition principle—the idea that a quantum object can exist in multiple states at the same time. The new test is based on examining the quantum rotation ...
Researchers have developed a new type of organic vortex laser, which is a laser that emits a helical beam of light. In the future, miniature arrays of these vortex lasers, each with a slightly different spiral shape, may ...
By shining a laser along the inside shell of an incandescent light bulb, physicists have performed the first experimental demonstration of an accelerating light beam in curved space. Rather than moving along a geodesic trajectory ...
