Researchers realized a magnet that can optically switch the polarization plane of light by 90 degrees. Nature Photonics asked Shin-ichi Ohkoshi how his group achieved this feat.
Room-temperature, optically pumped GaAs/AlGaAs/GaAs nanowire lasers have been realized. Dhruv Saxena and Sudha Mokkapati from the Australian National University discuss this breakthrough.
Researchers have fabricated a voltage-tunable plasmonic crystal in a two-dimensional electron gas that operates at terahertz frequencies. Nature Photonics spoke to Eric Shaner, Greg Dyer and Greg Aizin about the observation of Tamm states at the crystal's edge.
Nature Photonics spoke to Anatoly Grudinin, founder of the fibre laser company Fianium, to gain insight into the vicissitudes in the industry over the past decade and future challenges that academia can help solve.
Clustering of dark and grey solitons in fibre lasers has been found to induce a turbulent regime similar to that of a rapidly flowing fluid in a pipe. Sergei Turitsyn from the University of Aston, UK, explains.
A sensor based on an array of piezoelectric ZnO nanowires on a light-emitting GaN substrate can generate high-resolution images of pressure distributions. Zhong Lin Wang tells Nature Photonics that it could lead to superior touch interfaces for electronic devices.
Stéphane Coen and Miro Erkintalo from the University of Auckland in New Zealand talk to Nature Photonics about their surprising findings regarding a weak long-range interaction they serendipitously stumbled upon while researching temporal cavity solitons.
A laser with a record low energy cost has now been demonstrated by using a laser cavity based on photonic crystals. Shinji Matsuo of NTT Photonics Laboratories in Japan talked to Nature Photonics about its significance.
Magnets are often electrically activated, but recent research has demonstrated various schemes that can control magnetization using light and photocarriers. Nature Photonics spoke to Petr Němec and Tomas Jungwirth about their recent work on a polarization-independent optical-torque approach.
Although there is much debate regarding whether graphene is more suitable than metals for use in plasmonics, the useful operational frequency ranges of these materials are complementary. Nature Photonics spoke with Fengnian Xia about his team's recent work on graphene plasmonics.
Complete quantum control of an electron spin qubit can be achieved using a long-lived quantum-dot spin qubit coupled to a GaAs-based photonic-crystal cavity. Samuel Carter from the Naval Research Laboratory says that this system could be used as a node in a quantum network.
The study of random lasers based on disordered, scattering media has become an active topic of research in recent years. Nature Photonics spoke to Hui Cao from Yale University about developments in the area, potential applications and future opportunities.
Capturing the dynamics of atoms and molecules using X-ray free-electron laser pulses requires femtosecond timing between the pump and probe beams. Nature Photonics spoke with Marion Harmand and Marco Cammarata about their progress.
Strain in photonic structures can induce pseudomagnetic fields and Landau levels. Nature Photonics spoke to Mordechai Segev, Mikael Rechtsman, Alexander Szameit and Julia Zeuner about their unique approach.
