Abstract

We present an experimental and numerical study of the wavelength dependence, near resonance, of the optical tweezer trap stiffness on three different dye-doped 1 μ m polystyrene spheres with peak absorptions at λ = 625 , 775, and 840 nm. Experimentally, an increase in the trap stiffness of 35 % on the red side of resonance was observed for the dye-doped spheres relative to polystyrene spheres without dye. Numerical simulations for spheres of different sizes, between 20 nm and 1 μ m , and for absorption strengths corresponding to peak extinction coefficient values between 0.0027 and 0.081 were also conducted. Numerical results showed a maximum increase in the trap stiffness of 35 % , which is consistent with experimental results.
