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 ...

This paper comprehensively analyzes exact solutions for the nonlinear long-short wave interaction system within the optical field. Consider two general techniques in this field, the Sardar ...

We built an open-source library of wave optics models — Chromatix — that enables optics simulations to be scaled efficiently on modern computing hardware. Chromatix solves computational optics ...

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 ...

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 ...
