Controllable Mechanical Dynamics in Golf-Tee Shaped Nanostructures

We investigate the mechanical dynamics of golf-tee nanostructures, a common macroscopic geometry whose nanoscale implementation has received limited attention in the emerging field of hybrid nanophotonics. Using a theoretical analysis of the golf-tee geometry–characterized by its broad head, cylindrical support, tapered bottom sidewalls, and axisymmetric structure–we examine the mechanical characteristics of individual resonators and pairwise coupling between resonators. We demonstrate mechanical coupling of tens of MHz, providing improved control compared to conventional cylindrical pillars. The controllable mechanical dynamics of golf-tee structures offer an alternative approach to conventional cylindrical pillars, with enhanced tunability for mechanically configurable metasurfaces and potential for mechanically reconfigurable photonic applications.
