Filime yo mu rwego rwo hejuru Litimaum niobate ya electro-optic modulatritor

Umurongo muremureModutor ya electro-opticna phirowave photon
Hamwe nibisabwa na sisitemu yitumanaho, kugirango abantu bakomeze gukora neza ibimenyetso, abantu bazafotora na electrons kugirango bagere ku nyungu zuzuzanya, kandi bazavuka. Modutor ya electro-optique irakenewe kugirango ihindurwe ryamashanyarazi kumucyo muriMicrowave Photonic Sisitemu, kandi iyi ntambwe yingenzi mubisanzwe igena imikorere ya sisitemu yose. Kuva ihinduka rya radiyo yerekana indangarugero ya Optique nigikorwa cya Analog, kandi gisanzweAmashanyarazi ya electro-optiqueKugira aho bihurira, hari kugoreka bikomeye ikimenyetso muburyo bwo guhindura. Kugirango ugere kumurongo wagereranijwe, ingingo ikoresha ya modulator isanzwe ifatwa murwego rwo kuboroga orthogonal, ariko ntigishobora kuzuza ibisabwa na photiave ya microwave ihuza umurongo wa modulator. Modulator ya electro-optique hamwe numurongo muremure birakenewe byihutirwa.

Imyitozo yihuta yo kumvikana igenamigambi rya silicon mubisanzwe igerwaho ningaruka zitwara ubuntu (FCD). Ingaruka za FCD ndetse na PN Ihuriro rya PN ntabwo arinkinamizi, zituma modulator ya silicon itagira umurongo ugereranije na lithium modulator. Lithium ibikoresho bya niobate byerekana nezaGuhinduka kwa electro-optiqueimitungo kubera ingaruka zabasuka. Mugihe kimwe, ibikoresho bya Niobate bifite ibyiza byinkunga nini, imiterere myiza ya modulation, guhuza byoroshye no guhuza simico-opticator, ugereranije na siliconi hafi ya " Filime ntoya Indimi ya Niobate (Lnoi) Electro-optator modulator ya eleductor yabaye icyerekezo giteganijwe. Hamwe niterambere rya firime yoroheje Indimi ya Niobate Ikoranabuhanga hamwe na WaveGguide Ikoranabuhanga, Iterambere ryinshi rya Filidu-Optic Niobate Modulator ninganda mpuzamahanga.

Ibiranga film yoroheje lithium niobate
Muri Amerika, DAP Igenamigambi ryagize ibikoresho bikurikira by'imiterere ya Litioium: Niba ikigo cya revolution ya elegitoronike zituma bishoboka, noneho impinduramatwara ya funics ishobora kwitwa izina rya burimwitiwe. Ibi ni ukubera kodiri ya sithium ihuza electro-optique, ingaruka nziza, ngaruka ya piezoelectric, ingaruka za thermoelectric, nkingaruka zamafoto muri imwe, gusa nkibikoresho bya silicon murwego rwa optics.

Kubijyanye no kohereza ibitekerezo bya optique, ibikoresho bya Inoc bifite igihombo kinini kuri chip yo muri chip kubera kwinjiza urumuri mu itsinda risanzwe rikoreshwa 15050nm. Sio2 na Silicon Nitride isobanura neza, kandi igihombo gishobora kugera kurwego rwa ~ 0.01DB / CM; Kugeza ubu, gutakaza igihome cya WaveGgude ya Trithium Niobate waveguide irashobora kugera ku rwego rwa 0.03DB / CM, kandi igihombo cya litiro ya niobate yo gukomeza kunoza urwego rwikoranabuhanga mugihe kizaza. Kubwibyo, filime yoroheje ya Niobate ya Niobate izerekana imikorere myiza yoroheje yinzira nyabagendwa nka fotositythertic inzira, shunt na micororing.

Ku bijyanye n'ibisekuru, inp ifite ubushobozi bwo gusohora urumuri mu buryo butaziguye; Kubwibyo, kugirango usabe fotosi ya microwave, ni ngombwa kumenyekanisha isoko ishingiye kuri dosiye ya fotoike ya fotoine ya photonic yinjijwe munzira yo gusunika cyangwa eptaxial. Kubijyanye na modulation yoroshye, yashimangiwe hejuru yo muri Filime ya Filime ya Niobate biroroshye kugera ku moko nini, voldage yo hepfo hamwe nigihombo gito cyo kwandura kuruta icp na si. Byongeye kandi, umurongo muremure wa electro-optique modulation yibikoresho bya film litium niobate nibyingenzi kuri porogaramu ya Microgariave.

Ukurikije inzira nziza, umuvuduko mwinshi electro-optique igisubizo cya film yo muri lithium gikora optique ya optique itwara amajwi ya optique. Kubisanzwe porogaramu ihuriweho na photon ya photon ikoranabuhanga rya platon, igenzura ryiza ryabagambiriye rifite ubushobozi bwo gusiganwa bwihuse, kandi ibiranga ibiranga ingufu za ultra-bike bihujwe neza nibisabwa byihutirwa byashize. Nubwo inp ishingiye kuri optique ya optique irashobora kandi kumenya inzira yihuta yo gufungura, cyane cyane iyo itarangwamo rya optique ryakajwe, rizaringirwa urusaku. Silicon, Sio2 na Silicon Nitride Ibikoresho bya Optique binyuze muburyo bwa optique cyangwa ingaruka zo gutabaza cyangwa ibibi bigize ingaruka zikoreshwa ryimbaraga nyinshi no guhindura buhoro. Iyo ingano ya Array ya Array yicyiciro ari nini, ntishobora kuzuza ibisabwa nibiyobyabwenge.

Kubijyanye no kongera ibintu bya Opplifique, Thesemiconductor oplifier amplifier (Soa) Hashingiwe kuri ISP yakuze kugirango akoreshe ubucuruzi, ariko ifite ibibi byo gukosora urusaku no hanze yububasha, bidafasha gusaba gukwirakwiza fotowave. Inzira ya Parametric ya Amvirific yoroheje-film lithium niobate waveguide ishingiye kubikorwa no guhinduka birashobora kugera ku bisabwa muri tekinoroji ya photon.

Kubijyanye no kumenya urumuri, filime yoroheje Indimi ihindura ibiranga neza mumucyo mumatsinda ya Nm 1550. Imikorere yubuzima bwamafoto ntishobora kugerwaho, kubwibyo gusaba phoons phoon, kugirango duhuze ibikenewe mubikenewe bya Phosefecylic akeneye kuri chip. Ingaas cyangwa Gutahura Ge-SI bigomba gutangizwa kuri foto ya foneic ihuriweho na pupation mugushiraho gusudira gusudira cyangwa guciriritse. Kubijyanye no guhuza na fibre optique, kubera ko fibre ya optique ubwayo nibikoresho bya sio2, uburyo bwa Sio2 WaveGguide ifite impamyabumenyi yo hejuru hamwe nuburyo bworoshye bwa fibre, kandi guhuza nibintu byoroshye. Mode Mode ya Diameter ya WaveGuide yabujijwe cyane film lithium niobate igera kuri 1μm, bityo ihinduka muburyo bwa optique, bityo bikaba bitandukanijwe muburyo bwo guhuza imiterere ya fibre nziza.

Muburyo bwo kwishyira hamwe, niba ibikoresho bitandukanye bifite ubushobozi bwo kwishyira hamwe cyane bitewe ahanini na radiyo yuzuye radiyo ya WaveGguide (yibasiwe nuburinganire bwumurima wa waveguide). Kubuzwa kwa WaveGgude cyane yemerera radiyoroheje ntoya igoramye, ifasha cyane kurangiza kwishyira hamwe. Kubwibyo, film-filime lithium wavegude ifite ubushobozi bwo kugera ku kwishyira hamwe. Kubwibyo, isura ya filime yoroheje litiro niobate ituma bishoboka ko ibipimo bya tithium bigira uruhare rwose "Silicon". Kugirango ushyire porogaramu ya microwave, ibyiza bya filime yoroheje lithium biragaragara.
