Abstract

We expect an increase in the efficiency of terahertz radiation generation both due to the short period of the optical pulse containing 2–3 oscillations, and due to the fact that the process is modeled in a gradient waveguide. The generation process can be accompanied by the formation of spatiotemporal optical-terahertz solitons (optical-terahertz bullets). In the case of an intense and short optical signal, for the optical component, it is necessary to take into account the group dispersion of the third order, the dispersion of the quadratic optical-terahertz nonlinearity. For the terahertz component, one should take into account its dispersion, intrinsic quadratic nonlinearity, and quadratic nonlinearity, which carries information about the phase of the optical pulse.
