Nonlinear Optics in Thin Films
Abstract
Two nonlinear phenomena with the potential for locking together two waveguides/lasers have been examined theoretically. Phase conjugation of a plane-wave incident field onto a waveguide supporting two guided pump beams is a potentially useful phenomenon. This process can be very power efficient because of the strong spatial confinement of the pump beams. Multi-reflection effects within the guiding film lead to oscillations in the signal with increasing waveguide thickness and incidence angle. Coupling between two waveguides can be achieved by the exchange of spatial solitons when a self-focusing medium is used between two parallel waveguides. Model calculations based on the powerful Beam Propagation Method have indicated transfer efficiencies as large as 80 percent.
