Underwater Laser Cutting Method Saves Energy, Optimizes Efficiency
The need for modern technologies to dismantle existing underwater infrastructure is growing due to increasing demand for renewable energy sources. For example, to bring a wind power plant in the sea up to higher powers, the existing old steel frames, which may be below sea level, must first be dismantled so that engineers can rebuild them to obtain these higher powers. In laboratory tests, researchers at the Fraunhofer Institute for Material and Beam Technology IWS (Fraunhofer IWS) have developed a shortwave green laser method for beneath-sea cutting that offers multiple advantages over commonly used techniques that use saws, automatic saw wires, and plasma cutters, for example.

Financing Moves Diamond Light Source Upgrade Forward
A nearly £520 million ($648.3 million) investment in the U.K.’s national synchrotron, Diamond Light Source, will lead to the implementation of three new flagship beamlines, as well as upgrades to existing beamlines. The U.K. Department for Science, Innovation, and Technology, together with the biomedical charity Wellcome, approved the facility upgrade project, with an investment of 86% from the U.K. government and 14% from Wellcome.

Precision Automation Principles for the Optimal Testing and Packaging of PIC Devices
Thu, Sep 21, 2023 1:00 PM - 2:00 PM EDT
Production-scale testing of silicon photonic devices continues to be a challenge due to the multi-degree-of freedom, high-precision, optical alignments required for wafer- and die-level testing. Wide variances in chip designs and coupling features complicate test procedures, making it difficult to identify a system capable of producing repeatable measurements across various topologies. Brett Heintz of Aerotech Inc. provides a guide for selecting precision motion equipment to minimize the impact of positioning errors on optical alignment test results. Presented by Aerotech.

The Past, Present, and Future of Optical Fiber
Tue, Sep 26, 2023 1:00 PM - 2:00 PM EDT
Hair-thin strands of glass, intrinsically transparent and strong, connect today’s world in ways that are unimaginable even 20 years ago. Over the past 50 years, glass optical fibers have advanced from passive low-loss conduits for light to active light-amplifying hosts to a myriad of nano-to-macro-structuring of core-clad combinations. John Ballato of Clemson University discusses this history as a looking glass into the future of optical fibers and its symbiosis with light to address the question: What can the next 50 years bring? Sponsored by Fibercore and Lumatec GmbH.
