Spectroscopy Method Could Lead to Better Optical Devices
A new spectroscopy method developed by a multi-university team takes advantage of a fundamental property of thin films — interference — and could help make better use of these materials in optical devices like LEDs and solar cells. "The key difference in our technique is we're looking at the energy as well as the angle and polarization at which light is emitted," said Rashid Zia, assistant professor of engineering at Brown University and one of the study's lead authors. "We can relate these different angles to distinct orientations of emitters in the film. At some angles and polarizations, we see only the light emission from in-plane emitters, while at other angles and polarizations, we see only light originating from out-of-plane emitters." |

Manipulating Light on Superconducting Chips
Light manipulated on a superconducting chip using a switch that shapes released photons in different waveforms could forge new pathways to building the quantum devices of the future — including superfast and powerful quantum computers. The unprecedented level of on-chip light manipulation was achieved at the University of California, Santa Barbara. |

Altechna - Brewster Type Thin-Film Polarizers
| Altechna e-shop www.InStockOptics.com presents brewster type thin film polarizers. Dielectric coated polarizers BK 7, FS, UVFS separate the s- and p-polarization components of high energy laser beams and are intended for intra and extra cavity usage. Typical polarization ratio is 200:1. Damage threshold reaches 10J/cm² at 1064nm for 8ns pulses. www.instockoptics.com [email protected] |
