#nonlinearoptics — Public Fediverse posts

To produce a specific optical effect, #PhotonicChips typically rely on a single, specific material. Researchers at MPL have now used two different materials within the same component, thereby combining two nonlinear optical effects.

Scientists have demonstrated that sunlight, as a natural light source, can generate quantum-entangled photon pairs. With their findings, the international #research team challenges the assumption that lasers are indispensable for preparing quantum states of light. The study published in Optica opens a path toward new sustainable and energy-efficient photonic quantum technologies.

Highly ordered films of chiral carbon nanotubes (CNTs) possess the ability to convert the color of light at a rate two to three orders of magnitude higher than conventional materials. This phenomenon is achieved through second harmonic generation, where two light waves combine into a single wave with twice the frequency and half the wavelength.

Excited to share a new colloquium by Prof. Andrea Cavalleri, a founding director of the MPI for the Structure and Dynamics of Matter 🎓✨ In his Nordita talk, he explores how coherent electromagnetic radiation can induce unexpected phases like magnetic order, ferroelectricity, and high-temperature superconductivity.

Full abstract: In this colloquium, I will discuss how coherent electromagnetic radiation, when tuned to drive collective modes in quantum materials, can be used to induce unexpected dynamical phases. An illustrative set of examples will be discussed for the nonlinear control of the crystal lattice, which is used to induce magnetic order in paramagnetic materials, ferroelectricity in paraelectrics, non-equilibrium superconductivity at high temperatures, and other dynamical phases. These studies open up new directions in fundamental research but also expose a set of phenomena that will inevitably be encountered if one wishes to use quantum materials in ultra-high bit-rate applications.
