Application of laser generated moth-eye structure for a periodic terahertz-wave generator
To improve the generation efficiency of terahertz wave from periodic terahertz-wave generator, femtosecond laser was employed to fabricated moth-eye structure on the reverse of the antenna substrate (LT-GaAs). The AR structured antennas had a 2.5–4.4 times improvement of the output at the frequency of 0.342 THz (calculated fout), 0.283 THz, 0.226 THz (experimental fout of generator without and with moth-eye structure), the improvement are 3 times, 2.5 times, and 4.4 times, respectively.
