is nowadays one of the most active field of research in Physics.
Since the discovery of the laser in the sixties, which allowed the
early studies on the response of materials on high power electromagnetic
fields, Nonlinear Optics has developed nowadays to a wide extent,
involving fundamental research in the study of light-matter interaction
and applicative research in the cutting edge domains of future technologies,
such as photonics, optical communications systems, optical storage
and interconnect, biomedical imaging and art diagnostics.
Today Nonlinear Optics
involves a large scientific community, ranging from theoretical
to experimental physicists, material scientists, telecommunication
engineers and mathematicians. Different materials are studied and
are shown to provide nonlinear optical effects, now even at low
laser intensities, thus providing direct potential applications.
The field of study of Nonlinear Optics goes from atomic vapors to
solid crystals, photorefractive media and glass materials, liquid
crystals and polymers, optical fibers and waveguides, just to cite
project we aim at developing a series of research activities in
the field of Liquid crystal Nonlinear
Optics and especially on the study of
the complex spatiotemporal dynamics that arise in spatially extended
systems when a large degree of interconnection is established between
different parts of the optical wave front. In this
framework, we will focus on two paradigmatic experiments:
- A nonlinear optical
passive cavity with a large transverse section
- A spatially extended
nonlinear medium with retro-injected optical feedback.
optical Pattern formation, phase singularities, phase transition,
front propagation, and rare events in optical liquid crystals.
