Nonlinear optics is the study of how intense light interacts with matter. The optical response of a material usually scales linearly with the amplitude of the electric field. At high powers, however, the material properties can change more rapidly. This leads to nonlinear effects including self-focusing, solitons and high-harmonic generation.
Lanthanide-doped inorganic nanocrystals are promising for optical imaging and biomedical applications. Here authors show that interstitial H+ doping-induced crystal-field perturbation enhances the photoluminescence intensity of lanthanide-doped inorganic nanocrystals.
This paper shows theoretical and experimental results of the electric field-induced second harmonic generation in a single metal-silicon nanostructure for an optical-induced control of the χ(2) susceptibility.
Dissipative optomechanics, once limited to low frequencies, now operates in a sideband-resolved regime, reshaping optical and mechanical spectra and paving the way for the individual addressing of different mechanical modes in a single device.
Lightwave electronics could enable the control of interactions in quantum materials and provide access to the quantum phases and quantum information of condensed-matter systems. This Review discusses the fundamental concepts of lightwave electronics and outlines key advances and potential applications.
We demonstrate the manipulation of nonlinear polaritons and their prolonged coherence by creating fully deterministic potential wells with the lithographic mesas to trap polaritons in a monolayer WS2 microcavity.
Measuring the transmission matrix of disordered structures has so far been limited to the domain of linear systems. Now it has been measured for nonlinear disorder, with exciting implications for information capacity.
Multi-colour light fields allow a nonlinear coupling between free electrons and propagating light by stimulated Compton scattering, without the need for near fields to mediate the interaction.
