Broadband Spectrum from a Photoconductive Emitter Spanning up to 13 THz


Broadband Spectrum from a Photoconductive Emitter Spanning up to 13 THz

Singh, A.; Pashkin, A.; Winnerl, S.; Helm, M.; Schneider, H.

We demonstrate here ultra-broadband THz emission from a Ge based photoconductive emitter with the gapless spectrum extending up to ~ 13 THz, twice as far as what has been previously achieved with other materials. THz emission properties of Ge based emitter are compared with that of GaAs based emitter.
