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 ...

A new publication from Opto-Electronic Sciences; DOI 10.29026/oes.2024.240009 , discusses a smart photonic wristband for pulse wave monitoring. Pulse waves are a prominent component of physiological ...

New York, NY—May 8, 2023—Researchers at Columbia Engineering have developed a new class of integrated photonic devices--“leaky-wave metasurfaces”--that can convert light initially confined in an ...

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 ...
