I-LiNbO3 Substrate
Incazelo
I-LiNbO3 Crystal inezimfanelo eziyingqayizivele ze-electro-optical, piezoelectric, photoelastic kanye ne-nonlinear optical.Ziyi-birefringent ngokuqinile.Asetshenziswa ku-laserfrequency double, optics nonlinear, Pockels cell, oscillator oscillator optical, Q-switching devices for lasers, other acousto-opticdevices, optical switches for gigahertz frequencies, njll. Kuyinto enhle kakhulu yokwenza ama-waveguide optical, njll.

I-LiNbO3 Substrate Incazelo:
I-LiNbO3 (lithium niobate) substrate ibhekisela ezintweni ezikristale ezivame ukusetshenziswa njenge-substrate noma i-substrate kumadivayisi ahlukahlukene kagesi nawe-optoelectronic.Nawa amanye amaphuzu abalulekile mayelana nama-substrates e-LiNbO3:
1. Isakhiwo se-Crystal: I-LiNbO3 iyikristalu ye-ferroelectric enesakhiwo se-perovskite.Iqukethe ama-athomu e-lithium (Li) kanye ne-niobium (Nb) ahlelwe ngengilazi yekristalu ethile.
2. Izici ze-Piezoelectric: I-LiNbO3 inezici eziqinile ze-piezoelectric, okusho ukuthi ikhiqiza amashaji kagesi uma ingaphansi kokucindezeleka komshini futhi ngokuphambene nalokho.Lesi sakhiwo siyenza ilungele izinhlelo zokusebenza ezifana namadivayisi we-acoustic wave, izinzwa, ama-actuator, njll.
3. Izakhiwo ze-Photoelectric: I-LiNbO3 nayo inezakhiwo ezinhle kakhulu ze-optical kanye ne-electro-optic.Inenkomba ye-refractive ephezulu, ukumunca ukukhanya okuphansi, futhi ibonisa into eyaziwa ngokuthi umphumela we-electro-optic, lapho inkomba yayo ye-refractive ingashintshwa yinkambu kagesi yangaphandle.Lezi zakhiwo zikwenza kube usizo ezinhlelweni zokusebenza ezifana namamojula okubona, ama-waveguides, ama-frequency double double, nokuningi.
4. Uhla olubanzi lokukhanyela: I-LiNbO3 inohlu olubanzi lokukhanyela, oluyivumela ukuthi idlulise ukukhanya ku-spectrum ebonakalayo neseduze ne-infrared.Ingasetshenziselwa ukwenza amadivaysi okukhanya asebenza kulezi zifunda zamaza amaza.
5. Ukukhula kwe-Crystal nokumayo: Amakristalu e-LiNbO3 angatshalwa kusetshenziswa izindlela ezihlukahlukene ezifana ne-Czochralski kanye namasu okukhula kwesixazululo se-top-seeded.Ingasikwa futhi iqondiswe eziqondisweni ezihlukile ze-crystallographic ukuze kutholwe izici ezithile zokubona nezikagesi ezidingekayo ekwenzeni idivayisi.
6. Ukuzinza okuphezulu kwemishini namakhemikhali: I-LiNbO3 izinzile ngokomshini nangamakhemikhali, okuyenza ikwazi ukumelana
