Germanium microparticles as optically induced oscillators in optical tweezers
W. H. Campos, T. A. Moura, O. J. B. J. Marques +4
Oscillatory dynamics is a key tool in optical tweezers applications. It is usually implemented by mechanical interventions that cannot be optically controlled. In this work we show…

How light absorption modifies the radiative force on a microparticle in optical tweezers
W. H. Campos, J. M. Fonseca, J. B. S. Mendes +2
Reflection and refraction of light can be used to trap small dielectric particles in the geometrical optics regime. Absorption of light is usually neglected in theoretical calculat…
