Integrated photonics based on nonlinear optical scattering

In this work we investigate the modeling of optical structures, such as optical fibers and crystalline lattices, whose optical potential exhibit a certain type of symmetry known as parity-time (PT) symmetry. These optical potentials describe the scattering of light in the structure by modulating the refractive index of the system and thus generating a nonlinear optical beam that propagates along the waveguide. These optical beams have low dispersion and low energy loss, and maintain their shape during propagation. Due to such properties these nonlinear optical pulses can be applied in the development of optical filters, as well as in the transmission and processing of nonlinear optical signals. These systems, which exhibit well-defined band structure, can be employed in integrated optics, incorporating the possibilities generated from quantum and nonlinear optics. Such applications can also innovate the perspectives and demands of quantum computing.
