The experimental observation of bright dissipative polariton solitons in a semiconductor microcavity excited on picosecond timescales paves the way for ultranarrow light–matter localization and next-generation ultrafast information processing.
Quantum physics offers a way to enhance the amount of information a photon can carry, with potential applications in optical communication, lithography, metrology and imaging.
Scientists have demonstrated strongly coupled photon states between two distant high-Q photonic crystal cavities connected by a photonic crystal waveguide. Remote dynamic control over the coupled states could aid the development of delay lines, optical buffers and qubit operations in both classical and quantum information processing.
Picosecond acoustic pulses can be used to shift the optical transition energy of a quantum dot towards the resonance frequency of a microcavity, thus temporarily causing the device to lase. This ultrafast modulation technique has significant potential for exploring phenomena throughout quantum physics.
Telecommunications component manufacturers across the globe have been affected by the recent flooding in Thailand, which has caused manufacturing facilities near Bangkok to shut down.
The demonstration that quantum information can be stored in a bulk-diamond crystal in the form of an optically excited phonon gives researchers a new type of mechanical solid-state quantum memory to explore.
Laser-driven spinning particles can be used to control the direction of nerve fibre growth. Michael Berns from the University of California at Irvine explains this control mechanism and its potential applications.
