12 April 2007What is it optical binding and how to study this phenomena
Optical binding uses the fact that each object placed into the optical field modifies this field and at the same time
interacts with other objects in the field. Under certain circumstances these objects can self-organize and create
so called "optically bound matter". This happens for various sizes of particles and therefore there is no unique
method for the theoretical description of the phenomena. If the objects are small compared with wavelength
then they can be approximated as single dipoles. On the other hand paraxial wave theory is acceptable for
particles with sizes in multiples of the wavelength. We develop a method based on coupled dipole method
(CDM) or also known as a discrete dipole approximation (DDA). This numerical method covers the range of
sizes when particles are comparable or smaller then wavelength. For some cases the comparison with paraxial
wave theory is also possible. Our aim is to specify conditions suitable for creation of optically bound systems
which are experimentally verifiable.
