Nature Photonics spoke to Hongjie Dai from Stanford University about bioimaging in the second near-infrared (NIR-II) spectral window and its clinical potential.
In recent decades, progress in developing better nonlinear materials has not been as rapid as wished. Here I propose that this may be explained by considering the simple view of nonlinear optical phenomena as being determined mostly by the length of interaction time between photons and matter. Tentative routes towards improvements in the efficiency of nonlinear optical phenomena are suggested.
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.
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.
Recollected by his colleagues as a creative and humble scholar with an indomitable will, Byoungho Lee was enthusiastic about realizing the holistic potential of holographic displays.
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.
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.
Early research towards bulk metamaterials and exotic properties has been supplanted by work on thin metasurfaces ripe for commercialization, as outlined in this Focus issue.
Geoffroy Lerosey, co-founder and CEO/CSO of Greenerwave, shares how tunable metasurfaces may shake up industries from automotive to wireless communications.
The 2022 Nobel Prize in Physics celebrates the profound impact of quantum entanglement, which underpins many modern quantum technologies such as quantum cryptography and computing.
Gabriel Popescu passed away in June 2022. He will be remembered as a creative leader in biophotonics, with pioneering contributions to quantitative phase imaging and spectroscopy, an engaging collaborator and a dear friend.
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.
A heat-powered emitter can sometimes exceed the Planck thermal-emission limit. We clarify when such super-Planckian emission is possible, arguing that far-field super-Planckian emission requires a distribution of energy that is not consistent with a unique temperature, and therefore the process should not be called ‘thermal emission’.
Nature Photonics spoke to Hillel Adesnik from UC Berkeley about the benefits of using photonic techniques in optogenetics and the key challenges laying ahead.
