Theory of Optical Tweezers [PDF]
Europhysics Letters (EPL), 1999 We derive a partial-wave (Mie) expansion of the axial force exerted on a transparent sphere by a laser beam focused through a high numerical aperture objective. The results hold throughout the range of interest for practical applications.

Optical Frequency Tweezers [PDF]
Physical Review Applied, 2022 We show a concept of optical frequency tweezers for tweezing light in the optical frequency domain with a high resolution, which is the frequency version of the optical tweezers for spatial manipulation of microscopic objects. We report the proof-of-principle experiment via frequency conversion inside a cavity only for the converted light.

Interferometric Optical Tweezers [PDF]
Optics and Photonics News, 1996 Abstract We report the first experimental demonstration of an optical trap that uses interference fringes for the trapping and micro-manipulation of microscopic objects. The finges can be generated either by two-beam interference or by projecting a reduced image of a Ronchi ruling on the sample plane.
