Izixazululo zokuhlinzeka nge-chip yekilasi lokuxhumana ngogesi

Ngokombono wezimo zohlelo lokusebenza eziqondile, i-laser chip, ekhiqiza ama-photon ngokugxuma kwama-electron, isibonelo, ihlanganisa izici ezihlukahlukene.Ngokusebenzisa kwayo isizukulwane se-photon, ingahlukaniswa cishe ibe ama-photon wamandla, ama-photon olwazi kanye nama-photon wokubonisa.Izimo zohlelo lokusebenza lwe-photon yamandla zifaka i-fiber laser, ubuhle bezokwelapha, njll. Izimo zohlelo lokusebenza lwe-photon yolwazi zifaka ukuxhumana, i-autopilot, ukuqashelwa kobuso beselula, imboni yezempi, njll. Izimo ezijwayelekile zohlelo lokusebenza lwe-display photon zifaka ukukhanya kwe-laser, i-laser TV. , izibani ezizenzakalelayo, njll.

Ukuxhumana okubonakalayo kungenye yezindawo ezisetshenziswa kakhulu zama-optical chips.Ama-optical chips emkhakheni wokuxhumana optical wonkana angahlukaniswa abe izigaba ezimbili: asebenzayo kanye ne-passive, futhi angaphinde ahlukaniswe ngokusebenza nezinye izilinganiso.Ngokomsebenzi wama-chips asebenzayo, angahlukaniswa abe ama-laser chips okukhipha amasignali okukhanya, ama-detector chips okuthola amasignali okukhanya, ama-modulator chips okushintsha amasignali okukhanya, njll. Ngokuqondene nama-passive chips, akhiwe ikakhulukazi ama-PLC optical splitter chips. , ama-chips e-AWG, ama-VOA chips, njll., asekelwe kubuchwepheshe be-planar optical waveguide ukuze ulawule ukudluliswa kwe-optical.Ukubuka okuphelele, i-laser chip kanye ne-detector chip yiyona esetshenziswa kakhulu, izinhlobo ezimbili eziyinhloko zama-optical chips.

Kusukela ochungechungeni lwemboni, iketango lemboni yezokuxhumana ukuze kusheshiswe ukwenziwa kwasendaweni enye indlela ukusuka ezansi nomfula ukuya ekuqhutshweni komfula, i-chip ekhuphukayo njengesixhumanisi "sentanyeni" esidingweni esiphuthumayo sokunye ukujula kokunye okunye kwasekhaya.Abathengisi bemishini esezingeni eliphansi abamelwe iHuawei kanye ne-ZTE sebengabaholi bemboni, kuyilapho inkambu yemojula ye-optical isiqede ngokushesha ukushintshwa kwendawo kule minyaka eyishumi edlule ngokwethembela kwibhonasi yonjiniyela, ibhonasi yabasebenzi kanye nezinzuzo ze-supply chain.

Ngokwezibalo ze-Lightcounting, munye kuphela umdayisi wasekhaya owayephakathi kwabayishumi abaphambili ngo-2010, futhi ngo-2021, abathengisi basekhaya abaphezulu abayi-10 sebengene engxenyeni yemakethe.Ngokuphambene, abakhiqizi bamamojula optical optical phesheya kancane kancane basengozini ngokwezindleko zabasebenzi kanye nokuphelela kwe-supply chain, futhi ngaleyo ndlela bagxile kakhulu kumadivayisi optical aphezulu kanye nama-chip optical optical anezingqimba eziphakeme.Mayelana nama-chips optical, imikhiqizo yamanje esezingeni eliphezulu isabuswa phesheya kwezilwandle, amandla aphelele abakhiqizi basekhaya nabaholi baphesheya kwezilwandle basenegebe.

Sekukonke, ngokombono wemikhiqizo, i-10G yamanje kanye nemikhiqizo ephansi elandelayo inezinga eliphezulu lokukhiqizwa kwasekhaya, i-25G inenani elincane labakhiqizi abangathunyelwa ngobuningi, ngaphezu kwe-25G ocwaningweni noma ekuhlolweni okuncane. isigaba sokukhiqiza, eminyakeni yamuva abakhiqizi bekhanda emkhakheni wemikhiqizo ephezulu ukusheshisa inqubekelaphambili esobala.Ngokombono wezindawo zokufaka izicelo, abakhiqizi bamanje basekhaya emakethe yezokuxhumana, ukufinyelela kwe-fiber optic kanye nokufinyelela okungenantambo ngezinga eliphakeme lokubamba iqhaza kulo mkhakha, kuyilapho emakethe yezokuxhumana yedatha esezingeni eliphezulu esezingeni eliphezulu nayo isiqalile ukusheshisa.

Ngokombono womthamo we-epitaxial, nakuba abakhiqizi basekhaya bobuchwepheshe be-laser chip core epitaxial bebonke basenendawo eyengeziwe yokuthuthukisa, ama-wafers e-epitaxial aphezulu asadinga ukuthengwa kumafekthri we-epitaxial international, kodwa ngesikhathi esifanayo angabona. abakhiqizi abaningi be-chip optical baqala ukuqinisa amandla abo e-epitaxial, baqala ukuthuthukiswa kwemodi ye-IDM.Ngakho-ke, ikhono lobuchwepheshe lokugxila emikhiqizweni esezingeni eliphezulu eshintshwayo, enekhono elizimele le-epitaxial design kanye namandla okulungiselela kumodi ye-IDM yokuthuthukiswa kwabakhiqizi basekhaya abanenzuzo enkulu yokuncintisana kulindeleke ukuthi ilethe amathuba abalulekile entuthuko, kanye nemikhiqizo ephezulu ukuvula ukushintshwa kwasekhaya & ukungena kwedijithali kwenkundla ukuze kuqale, kulindeleke ukuthi kuvulwe ngokugcwele indawo yokukhula yesikhathi esizayo.

Okokuqala, kusukela ekubukeni komkhiqizo, i-10G kanye nokushintshwa kwe-chip yasekhaya okulandelayo okuphansi kuyaqhubeka nokujula, izinga lendawo liphakeme.Abakhiqizi basekhaya sebefunde kahle ubuchwepheshe obuyisisekelo bemikhiqizo ye-2.5G kanye ne-10G, ngaphandle kwamamodeli athile emikhiqizo (njenge-10G EML laser chip) izinga lendawo liphansi uma kuqhathaniswa, iningi lemikhiqizo likwazile ukuzuza ukwenziwa okwasendaweni kokushintshwa.
