Iterambere ryubushakashatsi bwafirime yoroheje lithium niobate electro-optic modulator

Moderi ya electro-optique nigikoresho cyibanze cya sisitemu yitumanaho rya optique na sisitemu ya microwave. Igenga urumuri rukwirakwiza ahantu h'ubusa cyangwa optique ya optique ihindura indangagaciro yo kugabanya ibintu biterwa n'umuriro w'amashanyarazi washyizweho. Lithium gakondo niobateamashanyarazi ya optiqueikoresha ibintu byinshi bya lithium niobate nkibikoresho bya electro-optique. Ikintu kimwe cya kirisiti ya lithium niobate ikorerwa murwego rwo hejuru kugirango ikore umurongo wogukoresha binyuze muri titanium ikwirakwizwa cyangwa inzira yo guhana proton. Itandukanyirizo ryerekana itandukaniro riri hagati yurwego rwibanze nigitambambuga ni gito cyane, kandi umurongo woguide ufite ubushobozi buke bwo guhuza umurima. Uburebure bwuzuye bwa moderi yapakiwe electro-optique mubusanzwe ni cm 5 ~ 10.

Litiyumu Niobate kuri tekinoroji (LNOI) itanga inzira nziza yo gukemura ikibazo cyubunini bwa lithium niobate electro-optique modulator. Itandukanyirizo ryerekana itandukaniro riri hagati ya waveguide yibanze hamwe na cladding layer igera kuri 0.7, ibyo bikaba byongera cyane uburyo bwa optique bwo guhuza imbaraga hamwe ningaruka zo kugenzura amashanyarazi ya elegitoronike, kandi byahindutse ahantu h’ubushakashatsi mubijyanye na moderi ya electro-optique.

Bitewe niterambere ryikoranabuhanga rikora mikoro, iterambere rya moderi ya electro-optique ishingiye kuri platform ya LNOI ryateye imbere byihuse, ryerekana inzira yubunini buke kandi bikomeza kunoza imikorere. Ukurikije imiterere ya waveguide yakoreshejwe, moderi isanzwe yoroheje ya lithium niobate electro-optique modulator ziba zometse kuri moderi ya moderi ya elegitoroniki-optique, yuzuye imvangemodulatorna hybrid silicon ihuriweho na waveguide electro-optique modulator.

Kugeza ubu, kunoza uburyo bwo gukama byumye bigabanya cyane gutakaza firime yoroheje ya lithium niobate waveguide, uburyo bwo gupakira imisozi ikemura ikibazo cyikibazo cyo gutobora cyane, kandi kimaze kubona moderi ya lithium niobate electro-optique ifite voltage iri munsi ya 1 V igice cyumuyaga, kandi guhuza hamwe na tekinoroji ya SOI ikuze bihuye nuburyo bwo guhuza fotone na electron. Ubuhanga buke bwa firime lithium niobate ifite ibyiza mukumenya igihombo gito, ingano ntoya hamwe numuyoboro mugari wahujwe na electro-optique modulator kuri chip. Mubyukuri, byahanuwe ko 3mm yoroheje ya firime lithium niobate gusunika-gukururaM⁃Z modulatorUmuyoboro wa 3dB wa electro-optique urashobora kugera kuri 400 GHz, kandi umurongo wagutse wa moderi yoroheje ya firime lithium niobate modulator byavuzwe ko urenga 100 GHz, kugeza ubu ikaba ikiri kure y’urugero rwo hejuru. Iterambere ryazanywe no guhuza ibipimo fatizo byubatswe ni bike. Mu bihe biri imbere, duhereye ku gushakisha uburyo bushya nuburyo bushya, nko gushushanya electrode isanzwe ya coplanar waveguide nka electrode igabanijwe, imikorere ya modulator irashobora kurushaho kunozwa.

Byongeye kandi, kumenyekanisha moderi ya chip yamashanyarazi hamwe no kuri chip itandukanye itandukanye hamwe na laseri, detector nibindi bikoresho byombi ni amahirwe kandi ni ikibazo cyiterambere ryigihe kizaza cya moderi yoroheje ya lithium niobate modulator. Filime yoroheje lithium niobate electro-optique modulator izagira uruhare runini muri microwave Photon, itumanaho rya optique nibindi bice.
