Eminyakeni yamuva nje, ama-chips asekhaya abhekane nengozi "yokunamathela entanyeni".Abanye ochwepheshe baxoxile ngokuthi i-China ingakha ama-chips afuywayo eduze komzila wezobuchwepheshe wamazwe angaphandle, noma ithole enye indlela futhi ivule ithrekhi entsha ukuze ifinyelele ukudlula emakhoneni.Ngokusobala, umzila wakamuva unzima kakhulu.Njengamanje, le mizila emibili iyahambisana, futhi ngayinye inokuphumelela.
Ukwenziwa kwasekhaya kwe-photoelectric chip kufeza i-nanoscale okokuqala ngqa
Ngobusuku bangoSepthemba 14, ososayensi baseShayina bashicilele ucwaningo lwabo lwakamuva ephephabhukwini lezemfundo eliphakeme kakhulu emhlabeni elithi "Nature".Ngokokuqala ngqa, bathole isakhiwo esinezinhlangothi ezintathu esibhalwe ukukhanya kwe-nanoscale, okwenza intuthuko enkulu emkhakheni wokwenziwa kwesizukulwane esilandelayo se-photoelectric chip.Kungcono ngobaisikrini esiholayo esivumelana nezimo.Lokhu kusungulwa okukhulu kungase kuvule ithrekhi entsha yokwenziwa kwe-photoelectric chip esikhathini esizayo, futhi kulindeleke ukuthi kusetshenziswe ekwenzeni ama-chips edivayisi kagesi abalulekile njengamamoduli kagesi, izihlungi ze-acoustic, nezinkumbulo ze-ferroelectric ezingaguquki.Inamathemba okusebenza abanzi ekuxhumaneni kwe-5G/6G, i-optical computing, intelligence yokwenziwa nezinye izinkambu.
iparele lemboni kagesi, elisetshenziswa kabanzi phansi komfula
Ama-optical chips ayizici ezibalulekile emkhakheni we-photoelectric.amadivaysi e-photoelectric (okubizwa ngokuthi ama-optical chips e-China) ayingxenye ebalulekile yemboni ye-semiconductor yomhlaba wonke.Ngokuthuthuka okunamandla kwemboni ye-photoelectric semiconductor, ama-optical chips, njengezingxenye eziyinhloko zeketanga lemboni ekhuphuka nomfula, asetshenziswe kabanzi kwezokuxhumana, imboni, ukusetshenziswa, njll. izinkambu eziningi.Ngokwezigaba zikaGartner, izinto zikagesi ezithatha izithombe zihlanganisa iCCD, CIS, LED, photon detectors, photoelectric, laser chips nezinye izigaba.
Njengezingxenye eziyinhloko zemboni yezithombe zikagesi, ama-optical chips angahlukaniswa abe ama-chip optical asebenzayo nama-passive optical chips ngokuya ngokuthi ukuguqulwa kwesignali ye-photoelectric kuyenzeka.Ama-chip optical asebenzayo angaphinde ahlukaniswe abe ama-chips adlulisayo kanye nokwamukela ama-chip;i-passive optical chips Ihlanganisa ikakhulukazi ama-optical switch chips, ama-optical beam splitter chips, njll.Isikrini esiguqukayo se-P1.56.Kulo mbiko, sigxile ekuthuthukisweni kwezimboni, indawo yemakethe namathuba okwenziwa kwasendaweni kwama-chip optical asebenzayo afana nama-laser chips nama-photon discovery chips.
Kunezigaba eziningi ezingaphansi zama-optical chips, futhi imboni ihlanganisa imikhakha eminingi.Ngokungeziwe ekuhlukaniseni okusebenzayo/okungenzi lutho ngenhla, ama-optical chips nawo angahlukaniswa abe izigaba ezine: i-InP, i-GaAs, i-silicon-based kanye nefilimu encane ye-lithium niobate ngokuya ngezinhlelo zezinto ezibonakalayo nezinqubo zokukhiqiza.I-InP substrate ihlanganisa ngokuyinhloko imodulation eqondile ye-DFB/Electro-absorption EML chips, ama-PIN/APD chips omtshina, ama-amplifier chips, ama-modulator chips, njll. Ama-substrates e-GaAs ahlanganisa ama-laser chips enamandla amakhulu, ama-VCSEL chips, njll. Ama-Silicon substrates ahlanganisa i-PLC, i-AWG , i-modulator, ama-optical switch chips njll., i-LiNbO3 ihlanganisa ama-modulator chips, njll.
Ama-optical chips avula amathuba okuthuthukisa
Ingxenye yekhulu leminyaka, ubuchwepheshe be-microelectronics buthuthuke ngokushesha ngokuvumelana noMthetho kaMoore.Kungcono ngobaimboni yokubonisa eholayo.Inkinga yokusetshenziswa kwamandla isiphenduke ibhodlela okunzima kubuchwepheshe be-microelectronics ukuyixazulula.Ukuthuthukiswa kwama-electronic chips kusondela emkhawulweni woMthetho ka-Moore, futhi kunzima ukuqhubeka nokufuna impumelelo ku-paradigm yobuchwepheshe bekhompyutha ye-elekthronikhi.Kubuchwepheshe obungase buphazamise obubhekene "nenkathi ye-post-Moore", ama-optical chips angenile emkhakheni wokubona wabantu.Ama-optical chips ngokuvamile enziwa ngezinto ezihlanganisiwe ze-semiconductor (I-InP nama-GaAs, njll.), futhi aqaphela ukuguqulwa okufanayo kwamasiginali we-photoelectric ngokukhiqizwa nokumuncwa kwama-photon okuhambisana nenqubo yokuguqulwa kwezinga lamandla langaphakathi.
I-Optical interconnection ingase futhi ithuthukise amandla okuxhumana ngaphakathi kwendawo yokudlulisela ngokusebenzisa izindlela ezihlukahlukene zokuphindaphinda (ezifana ne-wavelength division multiplexing WDM, ukusebenzisana kwe-mode division MDM, njll.).Ngakho-ke, ukuxhumeka kwe-on-chip optical okusekelwe kumjikelezo ohlanganisiwe we-optical kubhekwa njengobuchwepheshe obunamandla kakhulu, obungakwazi ukunqamula ngokuphumelelayo umkhawulo womzimba wamasekethe ahlanganisiwe wendabuko.Ukwenziwa kwasendaweni kwamamojula okubona, ama-fiber lasers, ama-lidar nezinye izixhumanisi ezimaphakathi nezansi nomfula ochungechungeni lwezimboni kuqhubeka kahle.Njengamanje, izwe lami liphansi komfula
amasegimenti afana namamojula optical, ama-fiber lasers, nama-lidar anokuncintisana okuqinile, futhi ukwenziwa kwasendaweni kwezinkambu ezihlobene kuzoqhubeka nokuthuthuka.Ngokuya ngamamojula abonakalayo, ngokwezibalo ezikhishwe yi-Lightcounting ngoMeyi 2022, abakhiqizi baseShayina bazothatha abakhiqizi abayisithupha kwabayishumi abaphezulu be-optical module emhlabeni ngo-2021.
Inqubekelaphambili kanye nendlela yokuphuma embonini ye-optical chip yaseChina
Emakethe yasekhaya, eqhutshwa ukwanda okukhulu kwesidingo esingaphansi komfula eminyakeni yamuva, abakhiqizi basekhaya bazamile ukwakha imboni ye-optical chip yaseChina ngokucwaninga nokuthuthukiswa kobuchwepheshe, ukuthengwa kwamanye amazwe nezinye izindlela.Ukuntuleka kwama-chips optical asekhaya asezingeni eliphezulu kulethe amathuba amakhulu entuthuko embonini.Ngokusekelwa kwezinqubomgomo, imboni yezwe lami ye-optical chip ithuthuke ngokushesha.Ilungeleisikrini esiholela esobala.Ikakhulukazi eminyakeni yamuva nje, isimo samazwe ngamazwe asizinzile, futhi izigameko zokuhlinzekwa kwamanye amazwe kwama-chips asekhaya zenzeke kaningi.Ukushintshwa kwasekhaya nakho sekuphenduke isihloko esishisayo embonini yasekhaya ye-semiconductor eminyakeni yamuva nje, kuncike emizamweni eqhubekayo yezinkampani ezihamba phambili zasekhaya zama-optical chip.
E-China, kuyadingeka ukulungisa ukushiyeka emkhakheni wama-chips wendabuko we-elekthronikhi ngokushesha ngangokunokwenzeka, kodwa futhi nokwenza imizamo ekuhlelweni kwamasekethe amasha njengama-chips we-photoelectric ngokushesha ngangokunokwenzeka.Ngendlela ekabili, kuzokwenziwa imizamo yokubamba ithuba lomjikelezo omusha woguquko kwezobuchwepheshe kanye noguquko lwezimboni.
