Picometric Ballistic (non-Brownian) Thermal Movements in Photonic Nanostructures (FTu2K.1)
Presenter: Tongjun Liu, University of Southampton

Components of photonic nanostructures exhibit picometric thermal movements affecting their optical properties. We report the first observation of ballistic (non-Brownian) thermal motion of a microcantilever, at timescales shorter than those of the erratic Brownian regime.

(Withdrawn) Photothermal Response of Single Gold Nanoparticles Through Hyperspectral Imaging Anti-Stokes Thermometry (FTu2K.2)
Presenter: Mariano Barella, CIBION - CONICET

We present an implementation of anti-Stokes thermometry that is potentially applicable to any nanoparticle with detectable photoluminescence, requires no assumption or previous characterization of the nanoparticle, and delivers the photothermal coefficient of the nanoscopic system.

(Withdrawn) Thermal Effects - an Alternative Mechanism for Plasmon-Assisted Photocatalysis (FTu2K.3)
Presenter: Yonatan Sivan, Ben-Gurion University

We show that the claims in some of the most famous papers on the topic of plasmon-assisted photocatalysis are extremely unlikely to be correct and that the faster reactions are likely the result of heating.

Analysis of Dissipation Mechanisms and Thermal Dynamics in Nanophotonic Resonators Using Thermo-Optical Effect (FTu2K.4)
Presenter: MingKang Wang, NIST

We present a robust method to distinguish the absorption loss from other loss mechanisms in a nanophotonic resonator by characterizing its thermo-optical nonlinearity. Using this method, we analyze ten modes of drastically different quality-factors.

Optothermal Generation and Manipulation of Plasmons in in Atomically Thin Films (FTu2K.5)
Presenter: Eduardo Dias, ICFO - The Institute of Photonic Sciences

We demonstrate the ability of graphene and thin metal films to undergo ultrafast photothermal optical modulation under pump-probe conditions, with depths as large as >70% over a wide spectral range.

Solution-Processed Plasmonic Surfaces as Optical Components for Infrared Thermography (FTu2K.6)
Presenter: Jyotirmoy Mandal, University of California, Los Angeles

Plasmonic nanoparticle-coated metal substrates, created with common materials and scalable fabrication techniques, yield solar absorptance and LWIR reflectance comparable to yields of standard germanium-based optics used in thermography, but at a fraction of the cost.

Impact of Nonlocality on Polar Nanophotonics (FTu2K.7)
Presenter: Christopher Gubbin, University of Southampton

In nanoscale polar resonators local theories of the optical response can break down. Here we develop theories to understand these effects, demonstrating novel phononphoton interactions with applications in mid-infrared nanophotonics and optoelectronics.
