Makhiristo a Semiconductor THz: Makhiristo a ZnTe (Zinc Telluride) okhala ndi <110> owongolera amagwiritsidwa ntchito pamibadwo ya THz ndi njira yowongolera.Kuwongolera kwa Optical ndikusintha kwanthawi zambiri pama media omwe ali ndi vuto lalikulu lachiwiri.Kwa femtosecond laser pulses yomwe imakhala ndi bandwidth yayikulu zigawo zafupipafupi zimalumikizana wina ndi mnzake ndipo kusiyana kwawo kumatulutsa bandwidth kuchokera ku 0 kupita ku angapo THz.Kuzindikirika kwa kugunda kwa THz kumachitika kudzera pakuzindikira kwa malo aulere a electro-optic mu <110> kristalo wina wa ZnTe.Kugunda kwa THz ndi kugunda kowoneka kumafalikira mozungulira kudzera mu kristalo wa ZnTe.Kugunda kwa THz kumapangitsa kuti kristalo wa ZnTe ukhale wowirikiza kawiri womwe umawerengedwa ndi kugunda kowoneka bwino.Pamene kugunda kowoneka ndi THz kugunda kuli mu kristalo nthawi imodzi, polarization yowoneka idzazunguliridwa ndi THz pulse.Pogwiritsa ntchito λ/4 waveplate ndi polarizer yogawanitsa matabwa pamodzi ndi ma photodiode oyenerera, ndizotheka kupanga mapu a THz pulse matalikidwe poyang'anira kuzungulira kwa pulse polarization pambuyo pa kristalo wa ZnTe panthawi zosiyanasiyana zochedwa ponena za kugunda kwa THz.Kutha kuwerenga gawo lamagetsi lathunthu, matalikidwe ndi kuchedwa, ndi chimodzi mwazinthu zokopa za THz spectroscopy ya nthawi.ZnTe amagwiritsidwanso ntchito pa magawo a IR optical components ndi vacuum deposition.
