Optical Fused Silica Large-Core Fibers: The Influence of Design and Material on Fiber Performance Optical Fused Silica Large-Core Fibers: The Influence of Design and Material on Fiber Performance
Wed, Dec 8, 2021 1:00 PM - 2:00 PM EST
Optical fibers are used in a wide variety of applications, including biomedical procedures, industrial laser cutting and welding, and spectroscopy. Fused silica is often the material of choice. Nevertheless, there are several variations of fused silica that can influence fiber performance. Additional factors--such as numerical aperture or cladding-to-core ratio--have an impact. In this webinar, learn how different design parameters and materials influence performance and how to perfect the fiber design for specific applications. Presented by Heraeus Conamic (Heraeus Quarzglas GmbH & Co. KG).

Epitaxy and Processing: VCSELs, QCLs, and InGaAs Detectors Epitaxy and Processing: VCSELs, QCLs, and InGaAs Detectors
Thu, Dec 16, 2021 10:00 AM - 11:00 AM EST
The webinar offers perspective to industry specialists and experts who share a technological interest in the epitaxy, processing, and integration of vertical-cavity surface-emitting lasers (VCSELs), quantum cascade lasers (QCLs), and indium gallium arsenide (InGaAs) devices. Wlodzimierz Strupinski, Ph.D., and Marcin Gebski, Ph.D., of VIGO System SA explain the manufacturing process for achieving state-of-the-art compound semiconductors and devices. They are joined by colleagues, Iwona Pasternak, Ph.D., Walery Kolkowski, Ph.D., and Jacek Strupinski, Ph.D., for a live Q&A and industry discussion at the end of the webinar. Presented by VIGO System SA.
