Simplified description of optical forces acting on a nanoparticle in the Gaussian standing wave.
Original language description
We study the axial force acting on dielectric spherical particles smallerthan the trapping wavelength that are placed in the Gaussian standing wave. We derive analytical formulas for immersed particles with relative refractive indices close to unity andcompare them with the numerical results obtained by generalized Lorenz-Mie theory (GLMT). We show that the axial optical force depends periodically on the particle size and that the equilibrium position of the particle alternates between the standing-wave antinodes and nodes. For certain particle sizes, gradient forces from the neighboring antinodes cancel each other and disable particle confinement. Using the GLMT we compare maximum axial trapping forces provided by the Gaussianstanding wave trap (SWT)and single-beam trap (SBT) as a function of particle size, refractive index, and beam waist size.
