Abstract
The generation of broadband terahertz radiation by optical rectification in a gradient planar waveguide is investigated. The conditions for the capture of optical and terahertz pulses and collinear propagation of their bound states are studied. The waveguide structure significantly reduces the diffraction spreading of generated terahertz pulses in comparison to a homogeneous bulk medium.
