Controlling photothermal forces and backaction in nano-optomechanical resonators through strain engineering
Menno H. Jansen, Cauê M. Kersul, Ewold Verhagen
In micro- and nanoscale optomechanical systems, radiation pressure interactions are often complemented or impeded by photothermal forces arising from thermal strain induced by opti…
Optomechanical microgear cavity
Roberto O. Zurita, Cauê M. Kersul, Nick J. Schilder +2
We introduce a novel optomechanical microgear cavity for both optical and mechanical isotropic materials, featuring a single etch configuration. The design leverages a conjunction…
Optomechanical Synchronization across Multi-Octaves Frequency Spans
Caique C. Rodrigues, Cauê M. Kersul, André G. Primo +3
Experimental exploration of synchronization in scalable oscillator micro systems has unfolded a deeper understanding of networks, collective phenomena, and signal processing. Cavit…
Quasinormal-mode perturbation theory for dissipative and dispersive optomechanics
André G. Primo, Natália C. Carvalho, Cauê M. Kersul +3
Despite the several novel features arising from the dissipative optomechanical coupling, such effect remains vastly unexplored due to the lack of a simple formalism that captures n…
