Abstract

We report a theoretical analysis of the generation of broadband and multiple-peak terahertz radiation in aperiodically poled lithium niobate, whose sequence of opposite domains is optimized by simulated annealing (SA) algorithm. The full width at half maximum (FWHM) of the broadband terahertz radiation in our simulation is 0.26 THz. Both of the center wavelength and FWHM can be easily tuned by choosing proper objective functions. Terahertz radiation with wider and flatter FWHM can be achieved by increasing the length of the lithium niobate crystal. The two-peak terahertz generation is also provided as an example of multiple-peak with the central wavelength at 1.68 and 1.80 THz, respectively
