Thermal engineering at nanoscale
Thermal engineering at nanoscale
Controlling temperature landscape in nanoscale has innumerable applications from spatial light modulation to thermo-biology. In this research pillar we aim to engineer 3D temperature landscapes to achieve a wide variety of applications including spatial phase modulation using thermo-optical effect and (thermo)plasmonic catalysis

Thermodynamics at nanoscale
Thermodynamics at nanoscale
Measuring temperature dynamics at nanoscale is a non-trivial task because of the non-propagative nature of heat. In this research pillar we devise novel optical measurement techniques based on 3D phase imaging to investigate heat generation and diffusion in 3D with sub-micron spatial resolution.

Cavity-Optics
Cavity-Optics
The way matter interact with light field can be controlled by placing them in optical cavities. In such cases the strength of interaction, also called the coupling strength, defines the extent of modification of the properties of matter. We study different experimental approaches to probe light-molecule interaction both in strong and weak coupling regimes.
