Abstract :
We present a computational simulation of multiple optical tweezers based on double parallel interference. This method belongs to the interferometric optical tweezers, and we study the system model including the parameters such as the distribution of light intensity, concentration modulation, and viscous drag coefficient and so on. An intensity gradient is also produced strong enough to counteract the scattering force, resulting in a stable 3D confinement of the particle.
