FIG. 1.

(Color) (a) Optical image of the high-index fiber used for optical trapping and manipulation. (b) Schematic of a focused beam from a tapered bismuth lens fiber. is the fiber tip radius of curvature, is the spot size, and is the focal length. (c) Cross-polarizer image of a bipolar liquid crystal drop. Inset: sketch of the director field as inferred from the image. (d) Calculated focal length and (e) spot size for a lens fiber with a mode field radius of vs the fiber tip radius of curvature.

FIG. 2.

Experimental setup for manipulation and observation of liquid crystal drops. The lens fiber acts as both an optical trap by focusing laser radiation and as a probe by capturing the backscattered radiation.

Image of FIG. 3.
FIG. 3.

(Color) [(a)–(c)] Cross-polarizer images of a bipolar liquid crystal drop trapped with the fiber-optic tweezers for different orientations of its average optic axis; we achieved this by rotating the wave plate by (a) 0°, (b) 90°, and (c) 180°. The texture is recovered after 180° rotation. (d) Measured frequency of rotation for drops of (●) and (□) as a function of the power of a circularly polarized incident light. (b) Intensity modulation observed in the backscattered radiation due to the rotation of the trapped liquid crystal drop.
