Researchers at EPFL report a chip-scale ultrafast laser that matches tabletop femtosecond performance, a long-sought milestone in integrated photonics.

A Nature study shows bright squeezed vacuum can drive nonlinear laser interactions far more efficiently, reducing the need for destructive intensity levels.

Researchers say they transferred the polarization state of a single photon between two physically separated quantum dots over a 270-meter free-space link.

An IEEE Spectrum report highlights a MEMS photonics device small enough to project images at extreme miniaturization, with roots in quantum-computing hardware research.

A new quantum racetrack laser design could shrink spectrometer functions from laboratory systems down to microchip-scale devices.

Researchers say a newly reported 2D material shows promise for ultrathin waveplates, raising the prospect of smaller polarization-control components for imaging, displays, and satellite systems.

A paper titled “High-dimensional topological photonic entanglement” appears in the March 2026 issue of Science, signaling new work at the intersection of photonics, topology, and entanglement.

Chinese researchers developed a quantum dot device that emits photon pairs with 98.3% purity, one of the highest ever achieved in a solid-state system, advancing quantum networking.
