An in-band optical filter blocks broadband noise that effectively allows high gain but low-noise amplification for ultrashort-pulsed lasers.

Based on a magnetite-containing nanocomposite and an in-line fiber-optic Sagnac interferometer, the device could be used for mapping the brain’s magnetic fields.

Localized heating of a plasmonic substrate by a focused laser ablates or displaces 2D material structures transferred onto the substrate, enabling rapid, submicron, maskless patterning...

New editor-in-chief John Lewis thanks predecessor Conard Holton and expresses desire to continue a long tradition of editorial excellence.

Not all quantum computer approaches entail photonics, but several rely on high-precision lasers, single-photon detectors, and optical fiber.

From site surveys to active vibration control, steps can be taken to keep your superresolution microscope stable and ready to collect data.

Using a metrology device and corrective software, CNC polishers can now use deterministic polishing to directly achieve form errors of sub-100 nm.
