Abstract: Understanding photon-induced non-radiative photothermal relaxation dynamics at the nanoscale is essential for advanced photonics-based sensing, communication, energy conversion, and healthcare applications. In this research work we are developing a new tool to investigate laser-modulated non-radiative heat dissipation from photo-excited nanomaterials to study photothermal dynamics. Here, we propose an optical fiber Bragg grating based technique to probe time-resolved photothermal relaxation dynamics in nanomaterials. Further, our work leads to the development of electrode-free, broadband, and high-speed photodetector across the UV-Visible-Infrared wavelength spectrum. We are exploring proposed technique towards light-neural tissue interactions with potential applications in neuromodulation.

                                                                                         All are cordially invited.
