The reported phonon-laser frequency comb incorporates an ultrathin silicon nitride (SiN) membrane, coupled to an optical cavity. Circulating laser light exerts radiation pressure on the membrane, ...
A new study has been led by Prof. Xing-Hua Xia (State Key Lab of Analytical Chemistry for Life Science, School of Chemistry and Chemical Engineering, Nanjing University). While analyzing the infrared ...
Phonon polariton enhanced nano-IR contrast imaging platform. (a) Sketch of the substrate-enhanced nano-IR contrast imaging platform based on a polar crystal substrate under the metallic tip. (b) ...
In a recent article in Nature Materials, researchers explored a novel approach to boosting thermal transport across solid interfaces by activating hyperbolic phonon-polariton (HPhP) modes in hexagonal ...
(Nanowerk News) The advent of intense ultrashort coherent light pulses has revolutionized the spectroscopy field. On the one hand, they allow easy observation of various nonlinear optical effects and ...
