Editor in chief John Lewis discusses SPIE Photonics West and invites you to enjoy Laser Focus World’s February 2019 issue which includes trends in photonics technologies, applications...

Optical ray tracing software reveals temperature effects by performing a coupled analysis of a lens system’s structural, thermal, and optical performance.

The interplay between light waves and ultrasound signals now enables fiber-optic sensing of materials outside the optical fiber that do not interact with its core.

The smallest known lasers to date promise to help scientists better understand the mechanisms of disease, according to the researchers who developed them.

Combining a silicon avalanche-mode LED with a single-photon avalanche diode allows an intrachip photonic optocoupler to be made with standard CMOS technology.

Small silica particles can be easily confined at the center of optimized bowtie apertures, enhancing vibrational signals and improving chemical identification when using surface...

Unlike standard silica fibers with strong background noise that can obscure weak Raman signals, sapphire fibers are a better option for Raman imaging probes.

A silica Kagome-lattice hollow-core photonic-crystal fiber filled with nitrogen oxide emitting at 4.6 µm in the mid-IR could be useful for remote sensing and free-space communications...

A nanophotonic lens with a complex structure, placed over a light-emitting nanowire, greatly reduces the divergence angle of the light output.

As particles containing nuclear material decay, the physical recoil motion can be quantified and related to kinetic energy, which uniquely identifies the type of material present...
