Light-emitting fibres that suit integration with textiles are prepared by dip-coating a steel wire with an electroluminescent material and then cleverly wrapping the structure with a carbon nanotube sheet that functions as a transparent electrode.
A fibre probe that relies on frequency mixing in a nonlinear crystal provides an all-optical scheme for mapping the amplitude and phase of terahertz fields.
Quantum physics and gravitational physics remain separate due to the vastly different scales of time and space that they refer to. Now, research may point to links between them.
The introduction of periodic inversion in the geometry of a plasmonic metasurface markedly boosts the efficiency of nonlinear processes in ultracompact structures.
Elegant experiments performed with X-rays and a double slit formed from molecular oxygen have finally made it possible to realize and test a long-standing and famous gedanken experiment in quantum mechanics.
The development of a group IV semiconductor laser that is CMOS-compatible represents a step towards the creation of fully integrated electronic and photonic circuitry.
A fast scanning light-sheet microscope that produces multicolour, dynamic images of living tissue could provide fresh insights into the brain's neural circuits.
