Abstract
An original optical tweezers using two chemically etched fiber nano-tips is presented. Optical trapping of 1 micrometer polystyrene spheres is demonstrated at optical powers down to 2.6 mW and tip-to-tip distances up to 28 µm. Harmonic trap potentials are found by analyzing the trapped particle position fluctuations. The trap stiffness is deduced using three different models. Consistent values of up to 0.5 fN nm-1 are found. The trap stiffness is linearly decreasing with decreasing light intensity and increasing fiber tip-to-tip distance.
