Phononic Frequency Combs – A New Addition to Photonics, MEMS, Quantum Information Science and Material Nanoscience

Speaker: Adarsh Ganesan , the US National Institute of Standards and Technology

When: February 10, 2021 (Wed), 02:00PM to 03:00PM (add to my calendar)

This event is part of the Biophysics/Condensed Matter Seminar Series.

Phononic frequency combs (PFC) are the mechanical analogs of celebrated photonic frequency combs. These represent a newly documented physical phenomenon in the well researched physical domain of MEMS resonators [1]. The emergence of PFC is mediated by nonlinear modal coupling. Through a series of experiments with MEMS resonators, various features of PFC have now been identified. These include drive parameters for comb operation, hysteresis for comb spectrum tailoring and growth, saturation and attenuation mechanisms of combs, and nonlinear sensitivity to physical perturbations. My talk will describe the physics of phononic frequency combs and how these could be foundational to the fields of photonics, MEMS, quantum information science, and material nanoscience.
