Application Briefs: Materials
Ultrashort pulse (USP), or “ultrafast,” lasers emit extremely brief pulses of light, generally with duration of a picosecond (10-12 seconds) or less. The pulses...
Briefs: Photonics/Optics
An improved packaging approach has been devised for filling a hollow-core photonic-crystal fiber (HC-PCF) with a gas, sealing the HC-PCF to retain the gas, and providing for optical connections and,...
Briefs: Test & Measurement
A system that comprises optical and electronic subsystems has been developed as an infrastructure for a spectroradiometer that measures time- dependent spectral radiance of the daylight sky,...
Briefs: Photonics/Optics
Suitably configured whispering-gallery-mode (WGM) optical resonators have been proposed as delay lines for trains of short light pulses. Until now, it has been common practice to implement...
