Optical manipulation with nanofiber waveguides

To produce a nanofiber waveguide, we take a standard optical fiber, heat it up locally, and slowly pull until its thickness becomes comparable to the wavelength of light. Such ultrathin waveguides greatly facilitate many studies of light-matter interactions, ranging from the micro- down to the atomic scale. In this talk, I will give a brief overview of our projects, and focus on optical manipulation of small particles in the vicinity of a nanofiber.
