Once the weaklings of the laser world, unable to emit a few milliwatts continuously at room temperature, laser diodes have become workhorses. Today, they power the Internet, pump...

In considering what to write for this Editor's Desk, I made a list of article topics published in the issue that could reveal a theme.

In optical coherence tomography (OCT) imaging, a high lateral resolution typically means a short depth of field or reduced axial resolution.

Researchers have combined the most interesting properties of photonic crystals and hyperbolic metamaterials into an entirely new material.

A professor has received a grant to develop a new optical-fiber-based method of frequency conversion of light and other nonlinear-optical operations on light.

A team of researchers is using Brillouin-scattering-induced transparency (BSIT) to create one-way optical waveguides.

Cube-shaped, tiny, resonant optical antennas improve over spherical nanoantennas for directing ultranarrow beams of light where needed.

Testing the form of a rotationally symmetric aspheric surface to be made in quantity is often done using a computer-generated hologram (CGH).

A set of algorithms can robustly ascertain an object’s authenticity using optically acquired microstructures.

This month I interview the husband–wife team of Professor Ursula Keller and Dr. Kurt Weingarten.

A standoff Raman spectrometer allows sensing from 2.4 m away at standard 2-m-height standoff pipes in the network.

Scientists have established that algorithms applied to facial surface measurements can identify the severity of autism spectrum disorders.
