Paper Abstract

It is shown that the periodically poled lithium niobate slab waveguide with specific period of poling, (lambda) /ng (where (lambda) is a wavelength of emitted THz-wave, ng is a refractive index of group velocity of light) is capable to emit the difference frequency generation (DFG) in the direction normal to the surface of a waveguide. The general expression for power of DFG in doubly resonant cavity (resonance both at a pumping and at difference frequencies) has been obtained. According to estimation the power of DFG is 0.33 mW for pumping power 1 W. Thus the double resonant cavity-enhanced surface-emitted DFG enables to design compact solid-state source of THz waves with the output power sufficient for the practical applications.
