Using THz pump-probe experiments, the nonlinear interaction of spectrally narrow THz pulses is investigated with plasmonic oscillations in a 2D electron gas of an AlGaN/GaN grating-gate structures. Nonlinear effects are observed as ultrafast, pump-induced changes in THz transmission, with relative transparency strongly dependent on plasmonic mode excitation and saturating at pump fluences of ≈200 nJ cm<sup>−2</sup>. The strongest relative transparency, reaching 45% at 350 nJ cm<sup>−2</sup>, occurs under resonant excitation of a localized plasmon mode at the strong electrostatic modulation of 2DEG concentration.

However, rotating macroscopic particles using light fields with intensity, polarization, or phase variations is challenging, especially underwater, due to the low torque of electromagnetic fields. This study demonstrates stable optical trapping and switchable light-induced rotation of millimeter-scale liquid marbles (LMs) in a uniform, time-invariant DC magnetic field. These LMs, composed of self-assembled ferrofluid droplets encapsulated by superhydrophobic particles with high photothermal conversion efficiency, float on a fluid surface and are stably trapped via controlled surface tension forces. Light-induced photothermal interactions within the magneto-optical field generate significant angular momentum, driving rotation through the Kelvin body force—resulting from a thermo-magnetic gradient—and surface tension forces. This enables optically induced rotation of magnetically trapped coupled LMs, with angular velocity tunable via magnetic and optical field strength, fluid viscosity, and surface tension. Torques exceeding 170 nN·µm are achieved with a 200 mW CW laser, modulating underwater optical transmission at 1–4 Hz. This approach advances reversible optical torque generation and optical communication in fluidic systems. Additionally, ultrasonic waves modulate rotation by altering the nonequilibrium force distribution within ferrofluid LMs.</p>","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 20","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144606425","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Triplet–triplet annihilation UC is especially attractive due to its low UC thresholds and broadband, tunable absorption. However, state-of-the-art NIR-to-visible solid-state UC thin films made of PbS quantum dots and rubrene are limited by 1) low absorption of NIR photons, 2) inefficient energy transfer, and 3) parasitic back transfer processes, leading to low efficiencies unsuitable for wide application. Here, a multi-layer architecture that allows for strongly absorbing UC films with improved efficiencies is proposed. 5-tetracene carboxylic acid is used as an interlayer to improve energy transfer to rubrene and alleviate parasitic back transfer leading to a factor of five improvement in efficiency.
