Electrically Driven Topological Laser Bypasses Manufacturing Imperfections
Researchers from Nanyang Technological University and the University of Leeds have created what they believe to be the first electrically driven topological laser. The use of topologically protected photonic modes enables this laser to efficiently bypass manufacturing defects as well as corners.

Graphene Formed Under Microscope Is Small Enough for Electronics
Scientists at Rice University; the University of Tennessee, Knoxville; and Oak Ridge National Laboratory used a small, visible beam mounted to a scanning electron microscope (SEM) to form laser-induced graphene (LIG), a multifunctional graphene foam that is typically direct-written with an infrared (IR) laser into a carbon-based precursor material.

New Stainless Steel Mirror Mount
OptoSigma Corp.
OptoSigma’s new 25.4-mm stainless steel mirror mount features a hollow-frame design to maximize stiffness and reduce mass. Thermal repeatability tests validate the effectiveness of new frame design showing lower deflection and equivalent repeatability against rival mounts. Additional features include center-post mounting, built-in dowel pin keys, and adhesive wells, all in the industry’s most compact and affordable stainless steel mount.

2D Material Structures Can Emit Customized Light in Desired Color
Some atomically thin 2D materials can emit customizable light in the color desired when the materials are combined together to create an “artificial semiconductor.” The discovery, made by researchers at the University of Geneva (UNIGE) and the University of Manchester, could spur use of 2D materials on an industrial scale.

SPIE Photonics Europe 2020
March 29 - April 2, 2020 - Palais de la musique et des congrès - Strasbourg, France
Photonics Media Booth: LIT 3
SPIE Photonics Europe is the premier European optics and photonics research and development conference, bringing together over 1800 attendees every other year to address the most challenging issues facing the industry today. This year the program will include an expanded biophotonics track and a new conference on terahertz photonics, photosensitive materials, and photonics and plasmonics at the mesoscale. Top speakers will deliver presentations on timely topics, from 3D-printed micro-optics to computational microscopy. Additional topics to be covered in this cross-disciplinary event will include photonic glasses, photosensitive materials, and quantum technologies.

Getting Specific About Coating Specifications
Wed, Apr 15, 2020 1:00 PM - 2:00 PM EDT
In this webinar, the technical team at North American Coating Laboratories (NACL) will provide a basis for specifying, testing, and confirming that your coating needs are clearly stated on drawings and are clearly conveyed to your coating solutions provider. To achieve this, the NACL team asks that you let them know what challenges you have faced or are facing currently with regard to specifying and testing optical coatings and meeting your coating requirements. You can do this when you complete the registration process. The NACL team will review all responses and prepare a presentation that is customized to the concerns of the registrants.
