Izibonelelo kunye nokubaluleka kweFight Lithium Lithium I-Niobate kwi-Microwave ye-Microwave Photon
Itekhnoloji ye-microwive photonUnezinto eziluncedo kwebhedi enkulu yokusebenza, ubuchule obuqinileyo bokulungisa kunye nokulahleka okuphantsi komhlaba, okunamandla okwenza ibhotile yolwazi yemveli efana ne-radar, imfazwe ye-elektroniki, unxibelelwano kunye nolawulo. Nangona kunjalo, inkqubo ye-microwave photon esekwe kwizixhobo ezi-grite ineengxaki ezinje ngemithanga enkulu, ubunzima obunzima kunye nokuzinza okungalunganga kunye nokuzinza okungekho gwenxa, nto leyo ethintelayo iqonga le-microwerne kunye neqonga le-chiat. Ke ngoko, itekhnoloji edibeneyo ye-microwave iba yinkxaso ebalulekileyo yokwaphula isicelo se-microswave photon kwiNkqubo yokuFunda emkhosini kwaye idlale ngokugcwele kwitekhnoloji ye-microwiave photon.
Okwangoku, ukudityaniswa kwetekhnoloji ye-Phototic esekwe kwi-Petotiki kunye ne-InP-isekwe itekhnoloji ye-PEMOTOIC ye-PELTOIC iye ngakumbi kwaye ivuthiwe emva kweminyaka yophuhliso kwicandelo lonxibelelwano olunjalo, kwaye uninzi lweemveliso zenziwe kwimarike. Nangona kunjalo, ukusetyenziswa kwe-microwaka photon, kukho ezinye iingxaki kwezi ntlobo zimbini zetekhnoloji yeTekhnoloji ye-Poton: Umzekelo, i-Anpro-Offilical Anlical Elearical ichasene ne-Microwive Phos Technology Technology Phoset Phop Technology Phoset photorate; Umzekelo, utshintsho lwe-silicon olukhethekileyo oluqonda ukutshintsha kwendlela ye-themol-of, i-piezoelectric, okanye intsingiselo yokutshitshiswa kwesantya esihamba kancinci, ukusela amandla kunye nokusetyenziswa kwamandla kwi-MARCY SCOPY Photon izicelo.
I-Lithium wiobate ibisoloko ilukhetho lokuqala lwesantya esiphezuluImoDolo ye-electro-opticIzixhobo ngenxa yefuthe elihle le-elektroniki optic. Nangona kunjalo, i-lithium yemveli ye-lithiumImodyuli ye-electro-opticalYenziwe ngemibandela enkulu ye-liobate ye-biobate, kwaye ubungakanani besixhobo sikhulu kakhulu, nto leyo engenakukwazi ukujongana neemfuno zetekhnoloji ye-photon edibeneyo. INDLELA YOKUFUNDA I-LINIIY LITIAR nge-Intanethi ye-Encro-Optical Optical Applical Applicall kwi-Microwave Photon System System ye-photon ibe yinjongo yabaphandi abachaphazelekayo. Ngo-2018, iqela lophando elivela kwiYunivesithi yaseHarvard eUnited States ixelwe itekhnoloji yokudibanisa i-photonic i-liobate yefilimu, eyakhiwe ngokuvakalayo kwindalo, kwaye kwangoko yabangela ukuba i-Pototication ye-Petonic Netnetions. Ukusuka kwimbono yesicelo se-photon ye-photon, eli phepha lijonga ifuthe kunye nokubaluleka kwetekhnoloji ye-Photon yokuHlanganisa esekwe kwifilimu ye-Lithium ye-Lithium ye-Niobete kuphuhliso lwetekhnoloji ye-microwiave.
Ifilimu yefilimu ye-Lithium ye-Lithium ye-Niobate kunye nefilimu emnyamaI-Lithium Niobate Modulator
Kwiminyaka emibini nje, i-liobate entsha yezinto ezibonakalayo ivele, oko kukuthi, ifilimu ye-Nithium ye-Niobate isuka kwi-Siobat ye-Lithium ye-liobate yindlela ye-Silica Buffer ye-Lithium ye-Lithium ye-Lithium ye-liobete kule iphepha. I-Ridge Wavegaides ezinokuphakama ngaphezu kwe-100 i-nanometers zinokubekwa kwizixhobo zefilimu ze-lithium ye-liobate ye-etchiming ye-liobeides ye-withiming ye-liobate ye-withgaides ye-withgaides ye-WitGegaides ye-0.02). Intsimi ye-microwave xa uyila imodyuli. Yiyo loo nto, kuyanceda ukufezekisa i-voltage esezantsi ye-wave kunye nebhendi yemodyuli enkulu kubude obufutshane.
Ukubonakala kwelahleko yelahleko ye-liobete ye-liobete ye-cimimicronWeGiide yaphula ibhotile yokuqhuba ye-Lithium ye-Lithium ye-Niobate ye-Inchobate. Isithuba se-electrode sinokuncitshiswa siye kwi ~ 5 μm, kunye nokugqobhoza phakathi kwendawo yombane kunye nentsimi ye-optical inyuka kakhulu, kwaye i-v voi ihla ngaphezu kwe-2.8 VIM. Ke ngoko, phantsi kwe-voltage enye ye-wave, ubude besixhobo bunokuncitshiswa kakhulu xa kuthelekiswa nemodyuli yesiko. Kwangelo xesha, emva kokufumana iiparamitha zobubanzi, ubukhulu kunye nexesha lokuhamba kwe-elektrode, njengoko kubonisiwe kumzobo, i-modlilator inokuba ne-bandwidth yemodyuli ephezulu kakhulu kune-100 GHz.

Umzobo
Thelekisa i-Lithium yefilimu ye-Lithium ye-liobete enemodyuli yemveli ye-Lithium ye-Liobate, iimodyuli ezisekwe kwi-Silicon kunye ne-Insmoricars phosfuide (i-Inp) yeemodyuli ze-elektronion kunye nezinye iimowudi ze-elektroniki eziphezulu, ezona parameter zentengiso zibandakanya:
(1) Imveliso ye-Wit-Wave-Waves
(2) I-3) yeemodyuli ze-3 ye-DB
. Ingabonwa kwitafile leyo ukuba i-Lithium yefilimu ye-Lithium ye-Lithium ineengenelo ezibonakalayo kwi-Bandwidth Bandwidth bandwidth, isiqingatha se-voltage, ilahleko ye-voltacal ye-ethe xhaxhe.
I-Silicon, njengelitye lezinto ezihlanganisiweyo, sele iphuhlisiwe kude, inkqubo ivuthiwe, i-Miniathering ilungele ukudityaniswa okukhulu kwezixhobo ezisebenzayo / zokudlulisa, kwaye kufundwe nzulu kwicandelo lonxibelelwano olunjalo. I-Elecro-Optical Modoring Modusmy ye-Silicon ye-Silicon ikakhulu i-raring-tion, inaliti yokuthwala kunye nokuqokelelwa komphathi. Phakathi kwazo, i-bandwidth ye-modlilatotor iphezulu kunye ne-Distrier yeCreen Argriers ye-Directions, kodwa ngenxa yokuba isiphumo sokugqobhoza kwendawo ye-Glosor kunye ne-odolo ye-odolo ye-odolo ye-odolo, eya kuthi ikhokelele ekunciphiseni kwemodyuli yemodyuli yokukhanya kunye nokugqwetha uphawu.
Imodyuli ye-IPP ineziphumo ezibonakalayo ze-electros ezibonakalayo, kunye ne-Multi-Well Premom Well Premory inokufumana izinga le-Ultra-high nemodrage ye-Ultra ePhakamileyo kunye neeMdlikhi eziphantsi zokuqhuba nge-v \ i-v \ i-v \ 0,56V. Nangona kunjalo, ukwahluka kwesalathiso sempikiswano kunye nendawo yombane kubandakanya umgca kunye ne-nonline thewor, kunye nokunyuka kobunzulu bendawo yombane kuyakwenza isiphumo sesibini. Ke ngoko, i-Silicon kunye ne-Inp ye-Inp ye-Oppic kufuneka isebenzise i-bias ukuya kwi-PN Junction xa besebenza, kwaye i-PN Junction iya kuzisa ilahleko yokukhanya. Nangona kunjalo, ubungakanani bemodyuli yezi zinto zimbini zincinci, ubungakanani be-Inp ye-InP ye-InP yi-1/4 yomthambo ye-LN. Ukusebenza kakuhle kwemodyuli, kufanelekile ukuxinana okuphezulu kunye nenethiwekhi yedijithali yedijithali yedijithali efana namaziko edatha. Iziphumo ze-electro-filical ze-lithium ze-liobate azinantsingiselo yokukhanya yokukhanya kunye nelahleko esezantsi, elungele umgama omde ohambelanaUnxibelelwano lwe-Opticalngesikhundla esikhulu kunye nenqanaba eliphezulu. Kwisicelo se-microwave photon, i-coeredical ye-elektrolical ye-Elecro-Optical ye-SI kwaye i-Inp ayifanelekanga kwiNkqubo ye-microwave photon efuna ubucala obukhulu kunye namandla amakhulu. Isixhobo se-lithium silungele kakhulu isicelo se-microwive photon ngenxa yemodyuli ye-electro-optic efanelekileyo.
