What is Optomechanics in Nanotechnology?
Optomechanics is an interdisciplinary field that combines elements of optics and mechanics at the nanoscale. In essence, it explores the interaction between light and mechanical systems. In the context of
nanotechnology, optomechanics aims to manipulate and control mechanical properties using light, or vice versa. This can involve the study of
nano-optomechanical systems (NOMS), which leverage optical forces to control mechanical movements or mechanical vibrations to affect optical properties.
