Fast free-electron laser targets the future

Following first lasing at LCLS-II — a coherent X-ray laser source driven by a 700-m superconducting linear accelerator — several upgrades are already in the works. Nature Photonics spoke to LCLS director Mike Dunne about LCLS-II commissioning hurdles as well as future plans.

Earth’s wobble probed by 16-m2 underground laser

A ring laser gyroscope, located at the Geodetic Observatory Wettzell in Southern Germany, measures variations in the Earth’s rotation. Nature Photonics spoke to a key researcher on the project, Ulrich Schreiber, about the system’s birth, teething issues, and how it may one day probe the El Niño effect.

The Encyclopedia of Photonics

Nature Photonics spoke with Rüdiger Paschotta, the founder of RP Photonics, about his online encyclopedia of photonics, the motivation behind it and future plans for the project.

Computing with light

Photonic processors are promising candidates for solving tough mathematical problems. Nature Photonics asked Yoshihisa Yamamoto, director of the Physics and Informatics Laboratories at NTT Research in USA, about the progress that is being made in realizing coherent Ising machines (CIMs).

Big lasers with a mission

Allen Weeks, Director General of the Extreme Light Infrastructure European Research Infrastructure Consortium, talks to Nature Photonics about the founding and future of the high-power-laser facilities, and stimulating a resurgence of physics in new EU member countries.

Sheets of light illuminate life sciences

Light sheet microscopy offers rapid 3D imaging of biological specimens while limiting photodamage. Nature Photonics spoke with Elizabeth Hillman of Columbia University about its capabilities, promising applications and present limitations.

Photonics makes a splash underwater

Optics is now going beneath the waves to give remote-operated vehicles and divers fast optical wireless data links. Nature Photonics spoke with Boon Ooi from KAUST, a leading researcher into underwater photonics research.

Nature Photonics spoke to Hongjie Dai from Stanford University about bioimaging in the second near-infrared (NIR-II) spectral window and its clinical potential.

An open question

Nature Photonics talks to Mark Hahnel, the founder and CEO of Figshare, a popular data repository, about the benefits and trends in making data open and shareable.

It’s a matter of time

Mordechai (Moti) Segev spoke with Nature Photonics about the fascinating topic of photonic time crystals — materials with a refractive index that is periodically modulated in time on ultrafast timescales — and their inspiring future ahead.

Metaoptics for the consumer market

Metalenz, a spin-out company from Harvard University founded in 2016, has launched its first metasurface-based product. Nature Photonics spoke with co-founder Federico Capasso about the company and its plans for flat optics.

Metamaterials for the masses

George Palikaras, President and CEO of Meta Materials Inc., discusses the challenges of commercializing metamaterials, learned on the path from a small start-up to a Nasdaq-listed company.

Metasurfaces get smart

Geoffroy Lerosey, co-founder and CEO/CSO of Greenerwave, shares how tunable metasurfaces may shake up industries from automotive to wireless communications.

A bright future for attosecond physics

The 2022 Wolf Prize in Physics has been awarded to Paul Corkum, Anne L’Huillier and Ferenc Krausz for their pioneering contributions to ultrafast laser science. Nature Photonics spoke to them about the milestones, challenges and future opportunities for the field.

Shaping light for optogenetics

Nature Photonics spoke to Hillel Adesnik from UC Berkeley about the benefits of using photonic techniques in optogenetics and the key challenges laying ahead.

Ever-evolving optical lattice clocks

The 2022 Breakthrough Prize in fundamental physics was awarded to Hidetoshi Katori and Jun Ye, who have been independently working on optical lattice clocks. They are the first winners from the photonics community. Nature Photonics interviewed Hidetoshi Katori on how he overcame difficulties in the study of optical lattice clocks, and what the next challenges are.

Clocks with a precise tick

Jun Ye from the University of Colorado was recently co-awarded the 2022 Breakthrough Prize in Fundamental Physics with Hidetoshi Katori for their pioneering research on optical lattice clocks. Ye spoke to Nature Photonics about the history of clocks and his future plans.

Redlining lasers for nuclear fusion

The National Ignition Facility at Lawrence Livermore National Laboratory reported over 1.3 MJ output, representing 70% of both input laser energy and official ‘fusion ignition’. Operations manager, Bruno Van Wonterghem, delves into the optics and what to expect next.

Trailblazing lasing

Nature Photonics spoke to Chihaya Adachi from the Center for Organic Photonics and Electronics Research (OPERA), Kyushu University, about the potential merits of, and hurdles facing, the development of organic semiconductor lasers.

Emitting organically

Franky So, from North Carolina State University, explains some hard truths for solution-processed emitters, but also that, fundamentally, there is no reason why OLEDS can’t ‘make it’.

Machine learning with light

Nature Photonics spoke to Aydogan Ozcan about the rise of artificial intelligence-enabled optics and the hurdles ahead.
