Optofluidic lens using suspended particles controlled by optical forces. (a) Schematic of the experimental geometry for beam manipulation. FDTD field output depending on the microsphere position: (b) on axis, (c) off axis, (d) leaving beam. (e) Insertion loss experimental and numerical simulation data with transmission regimes are identified. Reproduced with permission from P. Domachuk, M. Cronin-Golomb, B. J. Eggleton, S. Mutzenich, G.
