摘      要：Vigorous research efforts during the past several decades have successfully closed theterahertz gapbetween microwaves and infrared lig ht,offering new and increasingly efficient ways to produce,detect,and manipulate radiation fields in the terahertz(THz)frequency *** our laboratory,THz time he itspy IDS)and optical-pumрTHz-its have been routinely utilized as ulltrafast spectrosopy tools to investigate a variety of emerg ing quantum materinls pulses are produced by femtosecond laser excitation of photo-and metamaterials!.The ultrafast THz conductive antennas,semiconductor surfaces(InAs),and non-linear crystals(ZnTe,*** LiNbO,).Photoconductive an tennas and nonlinear crystals also al low for the coherent de-tection of these pulses in the time domain,with amplitude and phase spectra obtained in the frequency domain via fast Fourier *** such solid-state schemes are highly desirable in many aspects and thus also commonly utilized in many research laboratories and industrial applications,they typically sufer from limited bandwidths due to the absorption and frequency dispersion induced primarily by pho-non resonances,limiting THz applications such as spectroscopрy of emerging materinl,l,imaging ansd detection4.5 and biomedi-cal chuacterization.
