Icandelo elingundoqo

I-chip ye-Optical yeyomhlaba we-semiconductor, iyona nxalenye ephambili yezixhobo ze-optoelectronic.I-semiconductor iyonke inokwahlulwa ibe yizixhobo ezidityanisiweyo kunye neesekethe ezidibeneyo, iitshiphusi zedijithali kunye neetshiphusi ze-analog kunye nezinye iitshiphusi zombane zezesekethe ezidityanisiweyo, ii-chips ze-optical zizixhobo ezidityanisiweyo phantsi koluhlu lwamacandelo aphambili ezixhobo ze-optoelectronic.Izixhobo eziqhelekileyo ze-optoelectronic ziquka iilaser, ii-detectors njalo njalo.

Njengenxalenye ephambili yezixhobo ze-optoelectronic ezifana ne-lasers / detectors, i-optical chip iyona nto ingundoqo yeenkqubo zonxibelelwano zanamhlanje.Inkqubo yonxibelelwano yanamhlanje yinkqubo esebenzisa umqondiso we-optical njengomphathi wolwazi kunye nefiber optical njengendlela yokudlulisa ulwazi ngokuguqulwa kwe-electro-optical.Ukususela kwinkqubo yokudlulisa umqondiso, okokuqala, isiphelo sokudlulisa siqhuba ukuguqulwa kwe-electro-optical ngokusebenzisa i-chip optical ngaphakathi kwe-laser, ukuguqula umqondiso wombane ube ngumqondiso we-optical, odluliselwa ekupheleni kokufumana nge-fiber optical, kunye nokwamkela. isiphelo siqhuba uguqulo lwe-photoelectric ngokusebenzisa i-optical chip ngaphakathi kwe-detector, ukuguqula umqondiso we-optical ube ngumqondiso wombane.Phakathi kwabo, i-core photoelectric conversion function iqondwa yi-laser kunye ne-optical chip ngaphakathi kwe-detector (i-laser chip / detector chip), kwaye i-chip optical inquma ngokuthe ngqo isantya kunye nokuthembeka kokuhanjiswa kolwazi.

Imeko yesicelo

Ngokombono wemeko yesicelo esithe kratya, i-laser chip, eyenza iifotoni ngokutsiba kwe-electron, umzekelo, ibandakanya imiba eyahlukeneyo.Ngokusetyenziswa kwayo kwisizukulwana sefoton, inokwahlulwa ngokurhabaxa ibe ziifotoni zamandla, iifotoni zolwazi kunye neefotoni zokubonisa.Iimeko zesicelo se-photon yamandla ibandakanya i-laser fiber, ubuhle bezonyango, njl. njl , izibane zemoto, njl.

Unxibelelwano lwe-Optical yenye yezona ndawo zingundoqo zesicelo se-chips optical.Iichips ze-Optical kwintsimi yonxibelelwano lwe-optical ngokubanzi zinokwahlulwa zibe ngamacandelo amabini: asebenzayo kunye ne-passive, kwaye anokwahlulwa ngakumbi ngomsebenzi kunye neminye imilinganiselo.Ngokomsebenzi weetshiphusi ezisebenzayo, zinokwahlulwa zibe ziitshiphusi zelaser zokukhupha imiqondiso yokukhanya, iitshiphusi zomtshini zokufumana imiqondiso yokukhanya, iitshiphusi zemodyuli zokumodareyitha imiqondiso yokukhanya, njl. , iitshiphusi ze-AWG, iitshiphusi ze-VOA, njl., ezisekelwe kwi-planar optical waveguide technology ukulawula ukuhanjiswa kwe-optical.Umbono obanzi, i-laser chip kunye ne-detector chip yeyona nto isetyenziswa kakhulu, eyona nto ingundoqo kwiintlobo ezimbini ze-optical chips.

Ukusuka kwisixokelelwano soshishino, ikhonkco leshishini lonxibelelwano olubonakalayo ukukhawulezisa ukwenziwa kwendawo ukusuka ezantsi ukuya ekuqhubeni komsinga onyukayo, itshiphu enyukayo njengekhonkco "entanyeni" kwimfuno engxamisekileyo yolunye ubunzulu obungaphaya bendlela yasekhaya.Abathengisi bezixhobo ezisezantsi ezimelwe yiHuawei kunye ne-ZTE sele zinkokheli zoshishino, ngelixa intsimi yemodyuli ye-optical igqibe ngokukhawuleza ukutshintshwa kwendawo kwiminyaka elishumi edlulileyo ngokuthembela kwibhonasi yobunjineli, ibhonasi yabasebenzi kunye nezibonelelo zokubonelela.

Ngokwezibalo ze-Lightcounting, umthengisi omnye kuphela wasekhaya wayephakathi kwe-10 ephezulu ngo-2010, kwaye ngo-2021, abathengisi abaphezulu be-10 basekhaya baye bathatha isiqingatha semarike.Ngokwahlukileyo, abavelisi bemodyuli ye-overseas optical bancinci ngokuthe ngcembe ngokweendleko zabasebenzi kunye nokugqibelela kwekhonkco lokubonelela, kwaye ngaloo ndlela kugxininise ngakumbi kwizixhobo eziphezulu ze-optical kunye ne-upstream optical chips kunye nemigangatho ephezulu.Ngokubhekiselele kwi-chips optical, iimveliso zangoku eziphezulu zisalawulwa ngamazwe angaphandle, amandla onke abavelisi basekhaya kunye neenkokheli zaphesheya zisene-gap.

Ngokubanzi, ukusuka kumbono weemveliso, i-10G yangoku kunye neemveliso ezisezantsi ezisezantsi zinezinga eliphezulu lemveliso yasekhaya, i-25G inenani elincinci labavelisi abanokuthunyelwa ngobuninzi, ngaphezu kwe-25G kuphando okanye kwilingo elincinci. isigaba sokuvelisa, kwiminyaka yakutshanje abavelisi beentloko kwintsimi yeemveliso eziphezulu zokukhawulezisa inkqubela ebonakalayo.Ukusuka kwimbono yeendawo zesicelo, abavelisi basekhaya bangoku kwiimarike zonxibelelwano, ukufikelela kwi-fiber optic kunye nokufikelela kwi-wireless ukuya kwinqanaba eliphezulu lokuthatha inxaxheba kwintsimi, ngelixa i-market-oriented-oriented-oriented data communication market nayo iqalile ukukhawuleza.

Ngokombono we-epitaxial umthamo, nangona abavelisi basekhaya be-laser chip core epitaxial technology bebonke basenayo indawo yokuphucula, ii-wafers ze-epitaxial high-end zisafuneka zithengwe kwiifektri ze-epitaxial zamazwe ngamazwe, kodwa kwangaxeshanye banokubona. ngakumbi nangakumbi abavelisi be-chip optical baqala ukomeleza amandla abo e-epitaxial, baqala ukuphuhliswa kwendlela ye-IDM.Ngoko ke, ubuchule bobugcisa bokugxila kwiimveliso eziphezulu zasekhaya, kunye noyilo oluzimeleyo lwe-epitaxial kunye namandla okulungiselela kwimodi ye-IDM yophuhliso lwabavelisi basekhaya abanenzuzo ebalulekileyo yokhuphiswano kulindeleke ukuba ingenise amathuba abalulekileyo ophuhliso, kunye neemveliso eziphezulu ukuya. ukuvula ukutshintshwa kwasekhaya kunye nokungena kwedijithali kwintsimi ukuqalisa, kulindeleke ukuba kuvulwe ngokupheleleyo indawo yokukhula yexesha elizayo.

Okokuqala, ukusuka kwindawo yokujonga imveliso, i-10G kunye nelandelayo i-chip substitution yasekhaya ephantsi iyaqhubeka ijula, iqondo lokuhlala kwindawo liphezulu.Abavelisi basekhaya baye baqonda ngokusisiseko iteknoloji engundoqo ye-2.5G kunye ne-10G yeemveliso, ngaphandle kweminye imodeli yeemveliso (ezifana ne-10G EML laser chip) izinga lendawo liphantsi, uninzi lweemveliso ziye zakwazi ukufezekisa indawo yokutshintshwa.
