Abstract

Dual beam fiber traps are potentially useful for integrated trapping devices aimed at studying aerosols, and offer opportunities for cavity-enhanced traps. The alignment of such traps is typically seen to be critical. Here we explore the impact of the angular alignment of the optical fibers, and assess trapping viability as a function of misalignment and how particle dynamics change when interacting with displaced fibers. We find that good trapping capability for dual fibers tilted at the same angle, while more complex aerosol dynamics become apparent at higher single fiber tilt angles.
