Kwiminyaka yakutshanje, iitshiphusi zasekhaya ziye zajongana nengozi "yokunamathela kwintamo".Ezinye iingcali zixoxile ukuba i-China inokwakha iitshiphusi zasekhaya ecaleni kwendlela yobugcisa yamazwe angaphandle, okanye ifumane enye indlela kwaye ivule ithrekhi entsha yokufikelela kwiikona.Ngokucacileyo, le ndlela yokugqibela inzima ngakumbi.Okwangoku, ezi ndlela zimbini zihambelana, kwaye nganye inenkqubela phambili.
Ukwenziwa kwe-chip yefotoelectric yasekhaya ifezekisa i-nanoscale okokuqala
Ngorhatya lwe-14 kaSeptemba, izazinzulu zaseTshayina zapapasha uphando lwazo lwamva nje kwijenali yezemfundo ephezulu yehlabathi "Indalo".Ngethuba lokuqala, bafumana i-nanoscale ukukhanya-ikrolwe isakhiwo se-dimensional-dimensional ezintathu, okwenza impumelelo enkulu kwintsimi yokuvelisa i-photoelectric chip yesizukulwana esilandelayo.Kungcono kubaisikrini esikhokelayo esiguqukayo.Olu yilo lukhulu lunokuvula umkhondo omtsha wokwenziwa kwetshiphu yombane kwixa elizayo, kwaye kulindeleke ukuba isetyenziswe ekwenzeni iitshiphusi eziphambili zesixhobo sombane ezifana neemodyuli zombane, izihluzi zeacoustic, kunye neenkumbulo zeferroelectric ezingaguqukiyo.Inamathuba okusebenza ngokubanzi kwi-5G / 6G yokunxibelelana, i-optical computing, intelligence intelligence kunye nezinye iinkalo.
iperile yoshishino lombane, esetyenziswa ngokubanzi ezantsi
Iichips ze-Optical zezona zinto ziphambili kwibala le-photoelectric.izixhobo photoelectric (ezibizwa ngokuba chips optical e-China) ulwahlulo olubalulekileyo kushishino semiconductor yehlabathi.Ngophuhliso olomeleleyo lweshishini le-photoelectric semiconductor, ii-chips optical, njengezona zinto ziphambili kwikhonkco loshishino oluphezulu, zisetyenziswe ngokubanzi kunxibelelwano, kwishishini, kusetyenziso, njl njl.Ngokohlelo lukaGartner, izixhobo zefoto zombane ziquka iCCD, CIS, LED, photon detectors, photoelectric, laser chips kunye nezinye iindidi.
Njengezona zinto ziphambili kumzi mveliso wefotoelectric, iichips ze-optical zinokwahlulwa zibe ziichips ezisebenzayo kunye ne-passive optical chips ngokutsho nokuba uguqulo lwe-photoelectric lwenzeka.Iitshiphusi zamehlo ezisebenzayo zinokuphinda zahlulwe zibe ziitshiphusi ezihambisayo kunye nokufumana iitshiphusi;iitshiphusi ze-passive optical zibandakanya ikakhulu iitshiphusi zokutshintsha kwamehlo, iitshiphusi ze-optical beam splitter, njalo njalo.Isikrini seP1.56 esiguquguqukayo.Kule ngxelo, sigxile kwindlela yophuhliso lwamashishini, indawo yokuthengisa kunye namathuba okwenziwa kwendawo yeechips ezisebenzayo ezifana ne-laser chips kunye ne-photon zokubona iichips.
Kukho amacandelwana amaninzi ee-chips optical, kwaye ishishini ligubungela uluhlu olubanzi lwamasimi.Ukongeza kwi-classification esebenzayo / ye-passive ngasentla, ii-chips ze-optical nazo zingahlulwa zibe ngamacandelo amane: i-InP, i-GaAs, i-silicon-based kunye ne-thin-film i-lithium niobate ngokweenkqubo zezinto eziphathekayo kunye neenkqubo zokuvelisa.I-substrate ye-InP ikakhulu ibandakanya ukumodareyitha ngokuthe ngqo kwe-DFB/Electro-absorption modulation EML chips, detector PIN/APD chips, chips amplifier, chips modulator, etc. I-GaAs substrates ibandakanya iichips zelaser ezinamandla kakhulu, iichips zeVCSEL, njl. , imodyuli, iitshiphusi zokutshintsha kwamehlo njl., I-LiNbO3 ibandakanya iitshiphu zemodyuli, njl.
Iichips ze-Optical zingenisa amathuba ophuhliso
Kwisiqingatha senkulungwane, iteknoloji ye-microelectronics iphuhliswe ngokukhawuleza ngokuhambelana noMthetho kaMoore.Kungcono kwiumboniso okhokelwayo.Ingxaki yokusetyenziswa kwamandla iye yanda yaba yingxaki enzima kwitekhnoloji ye-microelectronics ukuyisombulula.Ukuphuhliswa kweetshiphusi ze-elektroniki kusondela kumda woMthetho kaMoore, kwaye kunzima ukuqhubeka nokufuna impumelelo kwi-paradigm yobuchwepheshe bekhompyutha.Kwitekhnoloji enokuthi iphazamise ejongene ne "post-Moore era", ii-chips ze-optical zingene kwintsimi yombono wabantu.Iichips ze-Optical ngokubanzi zenziwe ngezinto eziphathekayo ze-semiconductor (I-InP kunye ne-GaAs, njl.), kwaye ziqonde ukuguqulwa okufanayo kwezibonakaliso ze-photoelectric ngokusebenzisa isizukulwana kunye nokufunxa kweefotoni ezihamba kunye nenkqubo yangaphakathi yokutshintsha inqanaba lamandla.
I-Optical interconnection inokuphucula amandla onxibelelwano ngaphakathi kwendawo yokudlulisa ngokusebenzisa iindlela ezahlukeneyo zokuphindaphinda (ezifana ne-wavelength division multiplexing WDM, i-mode division interoperability MDM, njl.).Ngoko ke, i-on-chip optical interconnection esekelwe kwi-optical circuit edibeneyo ithathwa njengeteknoloji enokwenzeka kakhulu, enokuthi iphumelele ngokufanelekileyo kwi-bottleneck yomda womzimba weesekethe ezidibeneyo zendabuko.Ukwakhiwa kweemodyuli ze-optical, i-fiber lasers, i-lidars kunye nezinye i-middle-and-downstream links kwi-industrial chain iqhubela phambili kakuhle.Okwangoku, ilizwe lam lisezantsi
amacandelo afana neemodyuli ze-optical, i-fiber lasers, kunye ne-lidars zinokukhuphisana okuqinileyo, kunye nokwakhiwa kwendawo ehambelanayo kuya kuqhubeka nokuqhubela phambili.Ngokumalunga neemodyuli zamehlo, ngokwezibalo ezikhutshwe nguLightcounting ngoMeyi ka-2022, abavelisi baseTshayina baya kuhlala abathandathu kwabalishumi abaphezulu abavelisi bemodyuli emhlabeni ngo-2021.
Inkqubela kunye nendlela yokuphuma kwishishini le-chip ye-optical yaseTshayina
Kwimarike yasekhaya, eqhutywa kukwanda okukhulu kwemfuno esezantsi yomlambo kwiminyaka yakutshanje, abavelisi basekhaya baye bazama ukwakha i-China ye-optical chip industry ngophando lweteknoloji kunye nophuhliso, ukufunyanwa kwamanye amazwe kunye nezinye iindlela.Ukunqongophala kwee-chips ze-optical zasekhaya eziphezulu kuzise amathuba amakhulu ophuhliso kwishishini.Ngenkxaso yemigaqo-nkqubo, ishishini lelizwe lam le-optical chip liye laphuhla ngokukhawuleza.Ilungeleisikrini esikhokelela elubala.Ngokukodwa kwiminyaka yakutshanje, imeko yamazwe ngamazwe ayizinzile, kwaye iziganeko zokunikezelwa kwamanye amazwe kweechips zasekhaya zenzeke rhoqo.Ukutshintshwa kwekhaya kuye kwaba ngumba oshushu kushishino lwesemiconductor yasekhaya kwiminyaka yakutshanje, kuxhomekeke kwiinzame eziqhubekayo zezinye iinkampani eziphambili zasekhaya ze-optical chip.
E-China, kuyimfuneko ukwenza ukusilela kwintsimi yeetshiphusi ze-elektroniki zemveli ngokukhawuleza, kodwa kunye nokwenza iinzame zokubeka iisekethe ezintsha ezifana neechips ze-photoelectric ngokukhawuleza.Ngendlela emacala amabini, iinzame ziya kwenziwa ukuba kuthathwe ithuba lomjikelo omtsha wenguqu kwezobuchwepheshe kunye nenguqu kushishino.
