Protecting Photonic Quantum States Using Topology
Protecting Photonic Quantum States Using Topology
The use of topology to protect quantum information is well known to the condensed-matter community and, indeed, topological quantum computing is a burgeoning field of research. It is one of the competing avenues to demonstrate that quantum computers can complete certain problems that classical computers cannot. In photonics, however, we are only beginning to glimpse the potential of topologically protected photonic quantum states.

Robust Optical Materials for Aerospace and Laser Applications
Robust Optical Materials for Aerospace and Laser Applications
While single-crystal materials and ceramics are not as widely used for optical applications as glass, there are niche applications, such as aerospace, submarine optronic, and high-energy laser windows, for which these materials are favored. The choices for these applications often come down to three materials: sapphire, spinel, and aluminum oxynitride (ALON). Sapphire is a single-crystal material, while spinel and ALON are ceramic materials, and each has evolved markedly over the past several years in terms of producibility, affordability, and suitability.

Wearable Sensors Challenge Traditional Medical Technology
Wearable Sensors Challenge Traditional Medical Technology
From Apple to Fitbit to Garmin to Google, in the U.S. alone, dozens of companies are producing wearable sensors that record our movements as well as basic health information. Many of these devices rely on optical telemetry to read information about the body and transmit it to a smartphone via Bluetooth or Wi-Fi. While the growth of the smartphone market may be leveling off — in part because users are keeping their devices longer — the wrist and body are still prime, underexplored territory.

Kentek Corporation - NEW Laser Window ACR-2100 NEW Laser Window ACR-2100

Kentek Corporation
What are the key features of your product/service? Finally, 2100 nm protection in a large 24 x 36-inch polymer window. Why is it news worthy or innovative? Historically when users needed a laser protective window beyond 1400 nm and below 2700 nm they would be limited to mineral glass which is commonly sold in 6-inch square sheets, limiting the users view.

Scientists Image the Ultrafast Motion of a Rotating Molecule
Scientists Image the Ultrafast Motion of a Rotating Molecule
Scientists at the Center for Free-Electron Laser Science (CFEL) and the Max Born Institute (MBI) have used precisely tuned pulses of laser light to film the ultrafast rotation of a molecule. The resulting “molecular movie” tracks one and one-half revolutions of carbonyl sulfide (OCS), a rod-shaped molecule consisting of one oxygen, one carbon, and one sulfur atom. The revolutions take place within 125 trillionths of a second, at a high temporal and spatial resolution.

Light Controls the Electrical Properties in Quantum Materials
A new study from the University of Pennsylvania reports that Weyl semimetals, a class of quantum materials, have bulk quantum states whose electrical properties can be controlled using light. This work could contribute to a way to engineer and control quantum properties by changing light beam patterns, in addition to giving researchers a means to better observe quantum phenomena.

Airborne Lidar Provides More Complete Picture of Atmospheric Gases
Researchers from Deutsches Zentrum für Luft- und Raumfahrt eV (DLR), Germany’s national center for aerospace, energy, and transportation research, have developed a laser-based system for airborne measurement of atmospheric gases. The distribution of these gases in the troposphere, the lowest layer of Earth’s atmosphere and where weather takes place, plays a central role in Earth’s climate.

Waveguide Simulation with the Beam Envelope Method
Waveguide Simulation with the Beam Envelope Method
Tue, Sep 17, 2019 2:00 PM - 3:00 PM EDT
This webinar, presented by COMSOL, will demonstrate that the Wave Optics, Beam Envelopes interface in the Wave Optics Module, an add-on to the COMSOL Multiphysics® software, is suitable for analyzing various kinds of optical waveguides. You will learn how the Wave Optics, Beam Envelopes interface enables the analysis of long optics without having many mesh elements or any theoretical approximation, and you will learn how to set up a model. The speaker will also present advanced examples using the Wave Optics, Beam Envelopes interface.
