Ukubuyekezwa Kafushane kwe-Lithium Niobate Crystal kanye Nezicelo Zayo - Ingxenye 6: Ukusetshenziswa Kwe-Optical ye-LN Crystal

Ngaphezu komphumela we-piezoelectric, umphumela we-photoelectric weLNI-crystal icebile kakhulu, phakathi kwayo umphumela we-electro-optical kanye nomphumela we-optical nonlinear unomsebenzi ovelele futhi usetshenziswa kabanzi.Ngaphezu kwalokho,LNcrystal kungabawawuvamiselungisa i-waveguide yekhwalithi ephezulu ngokushintshaniswa kwe-proton noma ukusabalalisa kwe-titanium, futhifuthikungaba njalowawuvamiselungisa ikristalu ye-polarization ngezikhathi ezithile ngokuhlehla kwe-polarization. Ngakho-ke, i-LN crystal inezinhlelo zokusebenza eziningi in E-Oi-modulator (njengoba kukhonjisiwe esithombeni), i-modulator yesigaba, i-optical switch ehlanganisiwe,E-O Q-shintsha, E-Oama-deflector, ama-high voltage sensors, ukutholwa kwe-wavefront front, ama-optical parametric oscillator nama-superlattice e-ferroelectricnjll..Ngaphezu kwalokho,izicelo ze-LN crystal-basedi-birefringent wedgeaamapuleti e-ngle, amadivaysi e-holographic optical, izitholi ze-infrared pyroelectric namalaser we-erbium-doped waveguide nazo zibikiwe.

Ngokungafani nezicelo ze-piezoelectric, ise izinhlelo zokusebenza ezibandakanya ukudluliswa kwe-optical zidinga okuhlukileukusebenzaokweLNamakristalu.Fkuqalaly, iukusakazwa kwamagagasi okukhanya, ngeubude begagasi ukusuka kumakhulu ama-nanometer ukuya kuma-microns ambalwa, idinga ikristalu hhayi kuphelababe nokufana okuhle kakhulu kwe-opticalkodwa futhi kube ngokuqinile controlable of theamaphutha ekristalungosayizikuqhathaniswa namagagasiubude.Okwesibili,it ngokuvamile kuyadingekaOkweuhlelo lokusebenza olubonakalayo lokulawula isigaba nemingcele ye-polarization yegagasi lokukhanya elisakazeka kukristalu.Le mingcele ihlobene ngokuqondile nosayizi nokusatshalaliswa kwenkomba ye-refractive ye-crystal, ngakho-ke kuyadingeka ukuqeda i-in.ukucindezeleka kwangaphakathi nangaphandleye-crystal ngangokunokwenzeka. LNamakristalu ahlangabezana nezidingo zezinhlelo zokusebenza ezibonakalayo avame ukubizwa ngokuthi “ibanga le-opticalLNamakristalu”.

I-Z-eksisi kanyeX-i-eksisiamukelwa ngokuyinhloko ukuze kukhule oibanga le-pticalLNikristalu.Okwe-LN crystal, Z-eksisihaseliphezulu kakhuluijiyomethrii-symmetryokuyintoihambisana nei-symmetry yeinkambu eshisayo.Ngakho-keZ-i-eksisi ihambisana nokukhula kwekhwalithi ephezuluLN ikristaluokufanelezisikwe zibe izikwele noma amabhlogo amise okukhethekile.Amadivayisi we-Ferroelectric superlattice nawo akhonayenziwekusuka ku-Z-eksisiLNamawafa. I-X-eksisiLNIkristalu isetshenziswa kakhulu ukulungisa i-X-cut LNi-wafer, ukuze ihambisane nokusika, i-chamfering, ukugaya, ukupholisha, i-photoliography kanye nobunye ubuchwepheshe bokucubungula obulandelayo obuthuthukiswe inqubo ye-semiconductor.I-X-eksisiLNikristalu yiyoikakhulukaziesetshenziswa kakhuluEOama-modulators, ama-modulators wesigaba, izingcezu ze-birefringent wedge, ama-lasers we-waveguide nokunye.

LN Crystal-WISOPTIC

Ikristalu yekhwalithi ephezulu ye-LN (iseli ye-LN Pockels) ithuthukiswe yi-WISOPTIC.
