An Optica [#OPG_Optica] study presents a high-resolution spectroscopic investigation of the energy and linewidth of an exciton-polariton laser: https://bit.ly/3S1shHi Exciton-polariton lasers are a promising source of coherent light for low-energy applications, but are missing a detailed experimental study of their spectral purity. This research closes the gap by presenting the precise linewidth and energy shift measurements of laser emission from an optically trapped single-mode polariton condensate using a scanning Fabry–Pérot interferometer.

As we harness the power of quantum locking, we're stepping into a future where technology defies traditional limits. Excited to see how this revolutionary concept transforms industries and shapes our world! #QuantumLocking #Superconductivity #FutureTech #Innovation #Engineering #Science #LinkedInPost

🌟Exploring Quantum Locking: A Glimpse into the Future of Superconductivity!  ⚗️Quantum locking, also known as flux pinning, is one of the most fascinating phenomena in the world of quantum physics. This effect occurs when a superconductor becomes trapped within a magnetic field, leading to extraordinary behaviors such as levitation and frictionless motion. It was first observed in the 1950s! 🚅Imagine a world where trains hover seamlessly above tracks, moving with incredible speed and efficiency and medical devices operating with unprecedented precision! These are just a few of the potential applications of superconductivity and quantum locking! What do you think would be the most useful application of quantum locking? ⬇️ Follow @Science for more! #science #physics #quantumphysics

See our latest publication on the phenomenon of light-induced ferroelectricity in Nature Materials

👉 We have a new publication in Nature Materials Nature Portfolio: Michael Fechner, Michael Först and members of the Cavalleri group have gained new insights into the development of the light-induced ferroelectric state in SrTiO3. The fluctuations of the atomic positions in the material decrease when it is exposed to mid-infrared and #terahertz laser pulses. This may be a factor in the emergence of a more ordered dipolar structure than in equilibrium and the emergence of the #ferroelectric state. The team from the MPSD and the SLAC National Accelerator Laboratory / Stanford University carried out the experiments at the Swiss Light Source (Paul Scherrer Institute).

Optica Quantum [#OPG_OpticaQ] research from Univerzita Palackého v Olomouci displays a new kind of highly nonclassical states: https://bit.ly/3zxpajV The team demonstrated that the addition of photons into multi-mode twin beams makes them attractive for engineered two-photon excitations of atom, molecular, and other material systems under specific conditions. The researchers conclude the beams are promising as the quantum light source for virtual-state entangled-photon spectroscopy.

This Optics Letters [#OPG_OL] study from University of Southern California authors presents a novel coupled distributed feedback (DFB) laser system: https://bit.ly/3WugItI The laser system supports two lateral modes sharing a Bragg grating, enabling simultaneous lasing operation at two different frequencies. Compared to prior work, the new simplifies fabrication and offers greater compatibility with low-temperature grown GaAs (LT-GaAs) high-frequency photodetectors. Written by: Yuzhou G. N.
