Journal ArticleDOI
Parametric study of the forces on microspheres held by optical tweezers.
TL;DR: Optical-trapping forces exerted on polystyrene microspheres are predicted and measured as a function of sphere size, laser spot size, and laser beam polarization to form a first-order approximation to the forces that can be applied either directly to biological objects or by means of microsphere handles attached to the biological specimen.
Journal ArticleDOI
Laser trapping in cell biology
TL;DR: An analytical model was developed that accurately describes the forces exerted on dielectric microspheres while in a single-beam gradient force optical trap and predicts the existence of a stable trapping point and effective trapping range.
Journal ArticleDOI
Radiation trapping forces on microspheres with optical tweezers
TL;DR: In this article, a Gaussian beam electromagnetic field model and a ray-optics model were used to predict axial trapping forces on polystyrene microspheres in water.
Journal ArticleDOI
Large fanout optical interconnects using thick holographic gratings and substrate wave propagation
TL;DR: Substrate wave propagation and Bragg diffraction by multiplexed holographic gratings have been used to demonstrate a new 1-to-30 fanout optical interconnect having an overall diffraction efficiency of 87.8% and individual channel efficiency of 3.0 +/- 0.8%.
Journal ArticleDOI

TL;DR: It is concluded herein that optical scissors and tweezers can be used in combination to study the interaction of chromosomes with the mitotic spindle in cells where the peripheral regions of the spindle are unobstructed by intermediate filaments.
