20160030981 | METHODS AND DEVICES FOR OPTICAL SORTING OF MICROSPHERES BASED ON THEIR RESONANT OPTICAL PROPERTIES - Microspheres are sorted by resonant light pressure effects. An evanescent optical field is generated when light is confined within the interior of an optical element such as a surface waveguide, a tapered microfiber, or a prism. Microspheres brought within vicinity of the surface are subjected to forces that result from a coupling of the evanescent field to whispering gallery modes (WGM) in the microspheres. Alternatively, a focused laser beam is directed close to the edge of the microspheres to exert resonant optical forces on microspheres. Alternatively, standing optical waves are excited in the optical element. Optical forces are resonantly enhanced when light frequencies match WGM frequencies in the microspheres. Those microspheres for which resonance is obtained are more affected by the evanescent field than microspheres for which resonance does not occur. Greater forces are applied to resonating microspheres, which are separated from a heterogeneous mixture according to size. | 02-04-2016 |
