I-Crystal ye-ZnTe

Amakristalu e-Semiconductor THz: Amakristalu e-ZnTe (Zinc Telluride) anokuqondisa kwe-<110> asetshenziselwa ukukhiqizwa kwe-THz ngenqubo yokulungiswa kokubona.Ukulungiswa kwe-Optical inguquko yemvamisa yomehluko kumidiya enokuthambekela okukhulu kwe-oda lesibili.Kumapulse we-laser we-femtosecond anomkhawulokudonsa omkhulu izingxenye zemvamisa ziyasebenzisana futhi umehluko wazo ukhiqiza umkhawulokudonsa ukusuka ku-0 kuye ku-THz ezimbalwa.Ukutholwa kwe-THz pulse kwenzeka ngokutholwa kwe-electro-optic yendawo yamahhala kwenye <110> ikristalu eqondiswe ku-ZnTe.I-THz pulse kanye ne-pulse ebonakalayo kusakazwa nge-collinearly ngokusebenzisa ikristalu ye-ZnTe.I-THz pulse idala i-birefringence kukristalu ye-ZnTe efundwa ukushaya kwenhliziyo okubonakalayo okuhlukanisiwe.Uma kokubili ukushaya okubonakalayo kanye ne-THz pulse ku-crystal ngesikhathi esifanayo, i-polarization ebonakalayo izozungeziswa yi-THz pulse.Usebenzisa i-waveplate engu-λ/4 kanye ne-polarizer ehlukanisayo emishayo kanye nesethi yama-photodiode alinganiselayo, kungenzeka ukwenza kumephu i-THz pulse amplitude ngokuqapha ukujikeleza okubonakalayo kwe-pulse polarization ngemva kwekristalu ye-ZnTe ngezikhathi zokulibaziseka ezihlukahlukene ngokuphathelene nokushaya kwe-THz.Ikhono lokufunda inkambu kagesi egcwele, kokubili ukuphakama nokubambezeleka, kungenye yezici ezikhangayo zesizinda sesikhathi se-THz spectroscopy.I-ZnTe iphinde isetshenziselwe i-IR optical components substrates kanye ne-vacuum deposition.
