Optical manipulation of microspheres along a subwavelength optical wire

Optics Letters, 2007
The propulsion of 3 microm polystyrene spheres along a subwavelength optical wire is demonstrated. Velocities in the range of 7-15 microm/s are observed. Simulations are carried out to evaluate the evanescent field at the waveguide-water suspension interface.

Imaging and Optically Manipulating Neuronal Ensembles

Annual Review of Biophysics, 2017
The neural code that relates the firing of neurons to the generation of behavior and mental states must be implemented by spatiotemporal patterns of activity across neuronal populations. These patterns engage selective groups of neurons, called neuronal ensembles, which are emergent building blocks of neural circuits.

Optical Manipulation of Microscale Fluid Flow

Physical Review Letters, 2003
A novel optical method is used both to probe and to control dynamics in experiments on the spreading of microscale liquid films over solid substrates. The flow is manipulated by thermally induced surface-tension gradients that are regulated by controlling the absorption of light in the substrate.

Optical Manipulation in Aerosol Optical Tweezers

2011
Condensed phase optical manipulation techniques were pioneered by Ashkin, who demonstrated the first use of radiation pressure to guide particles in 1970 and later the first single-beam gradient force trap (optical tweezers) in 1986. Since then there have been numerous studies that make use of condensed phase optical tweezers, and that have sought to ...

Manipulation of solitons in optical fiber experiments.

Nonlinear Optics and its Applications 2024
In nonlinear physics, the fundamental soliton has drawn significant attention due to its pivotal role in dynamic systems. Its remarkable property lies in maintaining shape and resilience when interacting with other nonlinear waves. We explore this phenomenon in the context of single-mode optical fibers, employing the one-dimensional nonlinear ...

Manipulation and measurement by optical tweezers on a cell

MHS2013, 2013
By use of optical tweezers, micron to nanometer sized objects can be manipulated. This method has possibilities to realize surgery of a cell and investigation of mechanical property of a cell. In this article a novel scheme to enhance instantaneous radiation pressure force by use of a pulse laser and a measurement scheme are presented.
