Optical fiber brings ultralow signal loss to PICs

Using optical fiber as on-chip waveguides results in ultralow signal loss comparable to that of optical fiber at visible wavelengths. “For decades, optical fiber has achieved extraordinarily low propagation loss using germanium-doped silica,” says postdoctoral scholar Hao-Jing Chen, who co-led the research with Kellan Colburn, a Ph.D. student. But PICs have struggled to reach comparable

Program and control light’s chirality via a topology tweak?

Spin-orbit interactions of light Spin-orbit interactions of light “are usually associated with tight focusing, interfaces, anisotropic media, or nanostructures,” says Forbes. “In these cases, the spin and orbital degrees of freedom become coupled because the beam interacts strongly with a lens, a surface, or a material.” One surprising part for the team was seeing a
