Abstract-Giant self-induced transparency of intense few-cycle terahertz pulses in n-doped silicon



The results of high-field terahertz transmission experiments on n-doped silicon (carrier concentration of 8.7×1016 cm3) are presented. We use terahertz pulses with electric field strengths up to 3.1 MV cm1 and a pulse duration of 700 fs. Huge transmittance enhancement of 90 times is observed with increasing of the terahertz electric field strengths within the range of 1.5--3.1 MV cm1.
