Size-selective optical forces for microspheres using evanescent wave excitation of whispering gallery modes
Jack Ng and C. T. Chan
We show that when a microsphere is illuminated by an evanescent wave, the optical forces on- and off-whispering gallery mode (WGM) resonance can differ by several orders of magnitude. Such size-selective force allows one to selectively manipulate the resonating particles, while leaving those particl ... [Appl. Phys. Lett. 92, 251109 (2008)] published Thu Jun 26, 2008.
