Discrete Mode Laser Diodes with Very Narrow Linewidth Emission

By B. Kelly1, R. Phelan1, D. Jones1, C. Herbert1, et al.
26 March 2015

White Paper Lead ImageEx-facet, free-running low linewidth (~100 kHz), single mode laser emission is demonstrated using low cost, regrowth-free ridge waveguide Discrete Mode Fabry Pérot laser diode chips. These narrow linewidths are observed even at emission powers as low as 500 μW

Emissive Color Measurement: Measuring Chromaticity and Color Temperature of White LEDs

By Miriam Mowat, Applications Scientist
20 March 2015

White Paper Lead ImageIn this application note, Ocean Optics compares emissive color measurements of a NIST (National Institute of Standards and Technology) calibrated white LED from two of the company's spectrometers: the compact STS microspectrometer and the new Flame spectrometer.

Measuring LED Power and Irradiance with Calibrated Photodiodes

By Dr. Efi Rotem
17 March 2015

White Paper Lead ImageIn many industries, LEDs are replacing traditional broadband light sources, such as mercury, deuterium, Xenon and quartz-halogen lamps. Systems and applications transitioning to LEDs are reengineered in terms of optics, electronics, heat management, and more. Similarly, the equipment used by professionals to measure the output of these sources needs to be fitted for measuring LEDs.
