Is Nothing Better Than Something?
The idea of guiding light through hollow pipes dates to the 19th century, but solid-core fibers made much better optical waveguides. Now the emerging technology of hollow-core fibers has resurrected an old idea.

Silicon Carbide: From Abrasives to Quantum Photonics
Traditionally used for abrasives, LEDs and transistors, the material may enable scalable quantum and nonlinear photonics through direct integration of solid-state qubits into photonic circuits.

Tim’s Vermeer, Reconsidered
A recent documentary feature film, Tim’s Vermeer, proposes that Johannes Vermeer secretly used a catadioptric telescope and novel mirror–comparator procedure to create his sublime paintings of domestic interiors. How well does that bold hypothesis stand up to analysis?

Meeting the Future: Fiber
A widely cited 2018 paper in Optics Express considered how well optical transmission systems would meet the challenges ahead. Recently reported advances show that fiber is on track to meet those challenges. (For a look at advances in hollow-core fibers, see this month’s cover story.)
