Changing times

Global politics was on the agenda for a lot of presentations this year at Photonics West in San Francisco at the end of January. With the Trump administration only a week into office when the photonics trade fair began, SPIE had organised panel discussions and talks to address what the photonics community might expect from the new US administration, along with how photonics firms might navigate their way through periods of trade and political uncertainty such as Brexit. Walking the exhibition floor, it seemed one of the busiest Photonics West events I’ve attended, with OCT particularly strong among the biophotonics technology, new smaller spectrometers – Jessica Rowbury explores portable spectroscopy in her article on page 18 – plenty of activity around autonomous vehicles, and materials processing, silicon photonics and solid- state lighting also represented. There is a full report from the conference

starting on page 10, including what photonics executives had to say about the Trump administration and Brexit, Professor Dr Karsten Danzmann’s keynote on gravitational wave astronomy following the LIGO detections announced early in 2016, a panel discussion on the optical challenges in virtual reality, and updates on the BRAIN initiative, as well as the winners of the Prism Awards and the Startup Challenge. With plenty of innovation on display at the show, the photonics community continues to thrive.
