US immigration and trade policies provoke debate at Photonics West

San Francisco’s Golden Gate Bridge welcomes scientific visitors to Photonics West – except for those banned from travelling to the US.

By Margaret Harris at Photonics West in San Francisco

“I’m an immigrant. I stole one American job. I helped create hundreds of thousands of others.”

Deepak Kamra’s words caused a stir among listeners at Photonics West, the massive industry trade show and scientific conference that descends on San Francisco, California each winter. Speaking at a panel discussion on “Brexit, US Policy, EU and China,” the Delhi-born veteran of the Silicon Valley venture capital scene said that he expected the new US administration – which recently imposed a travel ban on visitors from seven majority-Muslim countries – to target Asian and South Asian technology workers next. Restrictions on the number of foreign-born students studying science, technology, engineering or mathematics (STEM) at US universities could follow. Ultimately, Kamra concluded, “We are going to lose a lot of qualified people.”

Spotlight on the International Year of Light (IYL 2015)

By James Dacey

As science-inspired global initiatives go, it’s fair to say that the International Year of Light and Light-based Technologies (IYL 2015) burned brighter than its organizers could have imagined. IYL 2015 set out to raise awareness of the crucial roles light can play in areas such as sustainable development, education and health, and it did so through festivals, workshops, publications and a plethora of other activities. A final report published this week details some of IYL 2015’s key achievements and describes some of the year’s most memorable activities.

Among the highlights identified in the report is the Physics World film series “Light in our Lives”, a set of short documentaries about the role of light in people’s everyday lives. We commissioned the films as an official IYL 2015 media partner, embracing the collaborative and international dimensions of the year by working with filmmakers across the world. They include a film about how LED lanterns are enabling students to study after sunset in a rural community in India, and another about how lighting technologies are bringing a modern twist to Day of the Dead celebrations in Mexico City (see above).

Physics World 2016 Focus on Optics and Photonics is out now

PWOPT16-cover-200By Matin Durrani

Research into optics, photonics and lasers is not only fascinating from a fundamental point of view. It’s also vital for technology, industry and applications in everyday life.

In the latest focus issue of Physics World, which is out now in print, online and through the Physics World app, you can find out about some of the latest research into optics and photonics – and how it’s being put to good use.

In our cover feature, take a look at some of the latest advances in invisibility cloaking – 10 years after first being demonstrated at microwave frequencies.

Leaping across the innovation divide

By Margaret Harris in Glasgow

If you’re the first speaker after lunch at a conference, how do you make sure your audience stays awake and engaged?

For Oliver Ambacher – who occupied the dreaded post-prandial slot during Wednesday’s applied photonics conference at Glasgow’s Technology and Innovation Centre (TIC) – the answer is simple. You pretend to jump off a cliff.

Ambacher, the director of the Fraunhofer Institute for Applied Solid State Physics in Freiburg, Germany, made his leap (actually, several leaps of varying lengths) to illustrate one of the toughest challenges in applied physics: the yawning gap between what academic researchers can provide, and what industry scientists need to turn that research into innovative products. This gap is sometimes called the “valley of death”, and Ambacher’s point was that the risks of leaping across it are generally higher on the industry side. “If I, whose heart is still in physics, jump into the valley of death, I lose funding, maybe a project,” Ambacher explained. “But somebody from industry, they may lose their job. So they cannot jump so far.”

Physics World 2015 Focus on Optics & Photonics is out now

PWoptics2015-cover-500By Matin Durrani

With the 2015 International Year of Light now in full swing, it’s time to tuck into the latest focus issue of Physics World, which explores some of the latest research into optics and photonics.

The focus issue, which can be read here free of charge, kicks off by looking at the giant laser interferometers underpinning the latest searches for gravitational waves. We also report on recent efforts to use optical instead of radio waves for satellite communication and have an interview with Ian Walmsley from the University of Oxford about the vital role that optics and photonics play in the UK’s new £270m Quantum Technologies Programme.

William Blake’s graphene sensor, boiling an egg inside out, quantum woo and more

 

By Hamish Johnston

Are you tired of the same old boiled egg staring up at you every morning? Then why not try this simple trick from the Japanese chef Yama Chaahan, who in the video above creates a boiled egg with the yolk on the outside and the white in the middle. There is angular momentum and fluid dynamics involved, and if you don’t understand Japanese, the Huffington Post has a step-by-step guide in English.

Photonics by the Bay

 

By Margaret Harris in San Francisco

The International Year of Light is a global celebration, but right now, it’s definitely got its heart in San Francisco. For the past five days, experts in optics, lasers and biomedical imaging have been converging on the “city by the bay” for the annual Photonics West conference, and I’ve joined them in order to learn more about the hot topics in optical science.

Physics meets biology in Baltimore

Biophysics in Baltimore: the T-shirt that does what it says on the tin.

By Susan Curtis in Baltimore, US

I’m in Baltimore this week for the 59th annual meeting of the Biophysical Society. The field of biophysics has grown rapidly in recent years as physics-based techniques have opened up new ways to study and understand biological processes, but with my limited knowledge of biology I was nervous that I would feel a little out of my depth.

The first talk of the “New and Notable” symposium helped to allay my fears. Michelle Wang is a physicist at Cornell University in the US who exploits optical techniques to trap and manipulate biomolecules. While established methods can only trap a single biomolecule at a time, Wang and her colleagues have pioneered the use of nanophotonic structures that can trap multiple biomolecules in a standing wave created within an optical waveguide.

“Our optical-trapping innovation reduces bench-top optics to a small device on a chip,” Wang told physicsworld.com when the team first reported their so-called nanophotonic standing-wave array trap last year. Since then, Wang and her colleagues have been working to integrate fluorescent markers with the nanophotonic trap to track the position of individual biomolecules, and have also been experimenting with optical waveguide materials other than silicon to improve performance and enable new applications.
