4inch 6inch Lithium niobate ifilimu yekristalu eyodwa ye-LNOI wafer

4inch 6inch Lithium niobate ifilimu eyodwa yecrystal LNOI wafer Isithombe Esifakiwe

Incazelo emfushane:

I-Lithium niobate inezindawo ezinhle kakhulu ze-electro-optical, nonlinear kanye ne-piezoelectric. Ngosizo lobuchwepheshe obuthuthukisiwe be-micro kanye ne-nano, amadivaysi e-photonics ahlanganisiwe asekelwe kumafilimu amancane e-lithium niobate (LNOI) kuma-insulators athuthukiswe kakhulu. Ngokuzayo, izinto ezisetshenziswayo ze-LNOI ezisebenza kahle zizosekela ukuthuthukiswa okuqhubekayo kwe-LNOI-based micro-nano optics, i-photonics ehlanganisiwe, kanye ne-microwave photonics. Ukukhiqizwa kwezinto eziphezulu ze-LNOI kuzoba isinyathelo esibalulekile ekusetshenzisweni kwezimboni zamadivayisi we-lithium niobate optoelectronics.

Omaka bomkhiqizo

Inqubo yokulungiselela izinto ze-LNOI ihlukaniswe kakhulu ngezinyathelo ezine ezilandelayo

(1) Ama-ion ajovwe ku-X-cut lithium niobate material kumandla athile, futhi angeniswa ongqimbeni lwesici ekujuleni okuthile ngaphansi kongqimba olungaphezulu lwe-lithium niobate;

(2) I-ion efakwe i-lithium niobate impahla ihlanganiswe ne-silicon substrate ene-oxide layer ukuze yakhe isakhiwo sokubopha;

(3) Isakhiwo sokuhlanganisa sanqanyulwa ukuze kwenziwe amaphutha okufakelwa i-He ion aguquke futhi ahlanganiswe ukuze akhe imifantu. Ekugcineni, i-lithium niobate yahlukaniswa eduze kwesendlalelo esinesici ukwenza izingcezu ze-lithium niobate ezisele kanye namawafa e-LNOI.

Izicelo kanye nezinzuzo ze-LNOI wafer

1--Amafilimu e-Lithium niobate piezoelectric (LNOI) ane-coefficient ephezulu ye-piezoelectric kanye ne-dielectric constant, engaguqula amandla omshini abe amandla kagesi noma amandla kagesi abe amandla emishini. Ngakho-ke, isetshenziswa kabanzi emkhakheni wezinzwa, njengezinzwa zokucindezela, izinzwa zokusheshisa, izinzwa zokushisa nokunye. Ngaphezu kwalokho, ifilimu ye-lithium niobate piezoelectric ingasetshenziswa futhi kumadivayisi e-acoustic namadivayisi wokudlidliza, njenge-piezoelectric ceramic transducer complex piezoelectric ceramic filter.

2-Ukuzinza kwefilimu ye-lithium niobate piezoelectric nakho kungenye yezinzuzo zayo. Ngenxa yokuzinza kwesakhiwo se-crystal kanye nokungabi namandla kwamakhemikhali, ifilimu ye-lithium niobate piezoelectric ingasebenza ekushiseni okuphezulu, umswakama ophezulu, i-asidi eqinile, i-alkali enamandla kanye nezinye imvelo enokhahlo, enokumelana nokugqwala okuhle nokuqina.

Ifilimu ye-3-Lithium niobate piezoelectric iyinto entsha ye-piezoelectric esebenza kahle kakhulu nokuzinza, futhi inethuba elibanzi lokusebenzisa. Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe, ifilimu ye-lithium niobate piezoelectric izosetshenziswa emadolobheni amaningi, ilethe ukunethezeka nokusungula izinto ezintsha ezimpilweni zabantu.
