These devices are the first to demonstrate simultaneous control of all four optical degrees of freedom, namely, amplitude, phase, polarization ellipticity, and polarization orientation--a world record ...

Earlier this year researchers developed sensing protocols that allow optical fibers to 'listen' outside an optical fiber where they cannot 'look', based on an interplay between light waves and ...

Terahertz (THz) wave generation has emerged as a frontier in both fundamental physics and practical applications, spanning imaging, spectroscopy and high-speed telecommunications. Central to these ...

The integration of optical systems in medical devices is a rapidly growing area of focus and investment within the medical technology sector. From surgical lasers and diagnostic imaging tools to ...

Customizable, US-made optical fiber payout solution earns distinguished honoree status for innovation in tactical ...

A career in optical physics or engineering means knowing about the behavior and properties of light, including its interactions with matter and its detection by instruments. Since the discovery that ...

Researchers have developed a new class of integrated photonic devices -- 'leaky-wave metasurfaces' -- that convert light initially confined in an optical waveguide to an arbitrary optical pattern in ...

Researchers at Columbia Engineering have developed a new class of integrated photonic devices—"leaky-wave metasurfaces"—that can convert light initially confined in an optical waveguide to an ...
