Gain-assisted plasmonic/dielectric nanoshells in optical tweezers: Non-linear optomechanics and thermal effects

Abstract:

We study theoretically the optomechanics of a dyed dielectric/metallic nanoshell in Optical Tweezers in a counter-propagating configuration. In addition, we consider the thermophoretic effects due to the interaction between the incident radiation and the nanoparticle metallic component.
