I-Eo Modulator Series: Kungani i-lithium niobate ibizwa nge-silicon optical

I-Lithium niobate yaziwa nangokuthi i-silicon optical. Kunesisho esithi "i-lithium niobate iwukuxhumana okubonakalayo ukuthi i-silicon iyini kuma-semiconductors." Ukubaluleka kwe-silicon ekuguqukeni kwe-electronics, ngakho-ke yini eyenza imboni ibe nethemba elikhulu mayelana nezinto zokwakha ze-lithium niobate?

I-Lithium niobate (LiNbO3) yaziwa ngokuthi “i-silicon optical” embonini. Ngaphezu kwezinzuzo zemvelo ezifana nokuzinza okuhle ngokomzimba namakhemikhali, iwindi elikhanyayo elibanzi (0.4m ~ 5m), kanye ne-coefficient enkulu ye-electro-optical (33 = 27 pm/V), i-lithium niobate iwuhlobo lwekristalu olunemithombo eningi yezinto ezingavuthiwe kanye nenani eliphansi. Isetshenziswa kabanzi kuzihlungi zokusebenza okuphezulu, amadivaysi e-electro-optical, isitoreji se-holographic, isibonisi se-holographic ye-3D, amadivaysi optical angaqondile, ukuxhumana kwe-optical quantum nokunye. Emkhakheni wokuxhumana okubonakalayo, i-lithium niobate ngokuyinhloko idlala indima yokuguquguquka kokukhanya, futhi isibe umkhiqizo ovamile kumoduli ye-electro-optical yamanje enesivinini esikhulu(I-Eo Modulator) imakethe.

Njengamanje, kukhona ubuchwepheshe obuthathu obuyinhloko bokushintsha ukukhanya embonini: ama-electro-optical modulators(Eo Modulator) asekelwe ekukhanyeni kwe-silicon, i-indium phosphide kanyelithium niobateizinkundla ezibonakalayo. I-silicon optical modulator isetshenziswa kakhulu kumamojula omfushane wokuxhumana kwedatha, imoduli ye-indium phosphide isetshenziswa ikakhulukazi kumamojula we-transceiver yenethiwekhi yokuxhumana ebangeni eliphakathi nendawo kanye nebanga elide, kanye ne-lithium niobate electro-optical modulator(Eo Modulator) isetshenziswa kakhulu ekuxhumaneni ibanga elide kanye nenethiwekhi ye-single-waverent 1G0b20 izikhungo zedatha ezinesivinini esiphezulu. Phakathi kwalezi zingxenyekazi ezintathu ezingenhla ze-ultra-high speed modulator, i-lithium niobate modulator yefilimu ezacile evele eminyakeni yamuva inenzuzo yomkhawulokudonsa ezinye izinto ezingeke zifane.

I-Lithium niobate iwuhlobo lwento engaphili, ifomula yamakhemikhaliLiNbO3, i-crystal negative, i-ferroelectric crystal, i-polarized lithium niobate crystal ene-piezoelectric, i-ferroelectric, i-photoelectric, i-nonlinear optics, i-thermoelectric nezinye izakhiwo zezinto ezibonakalayo, ngesikhathi esifanayo nomphumela we-photorefractive. I-Lithium niobate crystal ingenye yezinto ezintsha ezisetshenziswa kakhulu ezingaphili, iyinto enhle yokushintshanisa amandla ka-piezoelectric, impahla ye-ferroelectric, impahla ye-electro-optical, i-lithium niobate njengento esetshenziswa yi-electro-optical ekuxhumaneni kwe-optical idlala indima ekuguquleni ukukhanya.

I-lithium niobate material, eyaziwa ngokuthi “i-silicon ekhanyayo”, isebenzisa inqubo yakamuva ye-micro-nano ukushunqisa ungqimba lwe-silicon dioxide (SiO2) ku-silicon substrate, ibophe i-lithium niobate substrate ekushiseni okuphezulu ukuze kwakhiwe indawo yokuqhekeka, futhi ekugcineni kucwecwe ifilimu ye-lithium niobate. Ifilimu encane elungiselelwe i-lithium niobate modulator inezinzuzo zokusebenza okuphezulu, izindleko eziphansi, usayizi omncane, ukukhiqizwa ngobuningi, nokuhambisana nobuchwepheshe be-CMOS, futhi iyisixazululo sokuncintisana sokuxhumanisa okubonakalayo okunesivinini esiphezulu esikhathini esizayo.

Uma isikhungo soguquko lwe-elekthronikhi siqanjwe ngento ye-silicon eyenze kwaba nokwenzeka, khona-ke inguquko ye-photonics ingase ilandelelwe kuzinto ezibonakalayo ze-lithium niobate, ezaziwa ngokuthi "i-silicon optical" i-lithium niobate iwumsebenzi osobala ongenambala ohlanganisa imiphumela ye-photorefractive, imiphumela engaqondile, imiphumela ye-electro-optical, imiphumela ye-acousto-optical, imiphumela ye-piezoelectric kanye nemiphumela ye-piezoelectric. Izakhiwo zayo eziningi zingalawulwa ngokubunjwa kwekristalu, i-doping element, ukulawulwa kwesimo se-valence nezinye izici. Isetshenziswa kabanzi ukulungisa i-waveguide optical, switch optical, i-piezoelectric modulator,i-electro-optical module, i-generator yesibili ye-harmonic, i-laser frequency multiplier neminye imikhiqizo. Embonini yezokuxhumana okubonakalayo, ama-modulators ayimakethe yesicelo esibalulekile se-lithium niobate.
