Free space optical communication could offer high speed connectivity without the need of optical fibers. That's where groups like Akron come in. They are actively working to develop the next generation of light waves for free space optical communications. Using short coherence length optical sources, including ultrashort pulsed lasers, they believe they have found a way to overcome the hurdles holding these systems back from hitting the mainstream. On this episode, we are joined by Tom Chaffee, founder and CEO of Attochron, Jim Olson, senior VP of sales and marketing, and Wayne H. Knox, professor of Optics at the University of Rochester and consultant at Akron. "All Things Photonics"® is produced by Photonics Media and airs biweekly, on Tuesdays.

No one can be sure how this current trade war between the U.S. and China will end. But we’re feeling its impacts every day. While no person or business can escape the effects of this volatile market, semiconductor manufacturers have a unique challenge to deal with. Not only must they handle rising costs and taxes, but they also must figure out how to advance forward facing export restrictions from China. Rare earths vital in the production of semiconductors come primarily from China, but new controls will limit American companies’ access to those materials. In this Spotlight, we talk with TECHCET CEO and Founder, Lita Shon-Roy, to learn more about the origins of this trade war, how it impacts the semiconductor industry, and what it will take to bring this chapter of turmoil to a close. Spotlight from "All Things Photonics"® is a special series of intimate sit-down conversations with preeminent figures in our industry.

Additive manufacturing garners considerable attention — but the methods and underlying technology often take a back seat to the remarkable designs and properties of finished works. Lukas Hoppe, R&D director at Meltio, offers insights into the current laser-based additive manufacturing ecosystem. Hoppe discusses Meltio’s blue laser innovations as well as wire-laser metal 3D printing methodology. "All Things Photonics"® is produced by Photonics Media and airs biweekly, on Tuesdays.
