Kev sib txuas lus hauv chav kawm chip muab kev daws teeb meem

Lus piav qhia luv luv:

Optical chips yog cov tseem ceeb ntawm cov khoom siv optoelectronic, thiab cov khoom siv optoelectronic feem ntau suav nrog lasers, detectors, thiab lwm yam. Kev sib txuas lus kho qhov muag yog ib qho tseem ceeb tshaj plaws ntawm daim ntawv thov kev kho qhov muag, thiab daim teb no feem ntau muaj laser chips thiab ntes chips.Tam sim no, hauv kev lag luam digital kev sib txuas lus thiab kev lag luam kev sib txuas lus, ob lub lag luam uas tau tsav los ntawm ob lub log, qhov kev thov rau cov khoom siv kho qhov muag muaj zog, thiab nyob rau hauv Suav lag luam, tag nrho lub zog ntawm domestic manufacturers nyob rau hauv high-end khoom thiab txawv teb chaws cov thawj coj tseem muaj. qhov sib txawv, tab sis cov txheej txheem ntawm kev hloov pauv hauv tsev tau pib nrawm.

Core tivthaiv

Optical nti belongs rau thaj chaw semiconductor, yog lub hauv paus tseem ceeb ntawm cov khoom siv optoelectronic.Semiconductor tag nrho tuaj yeem muab faib ua cov khoom siv sib cais thiab kev sib xyaw ua ke, cov chips digital thiab analog chips thiab lwm cov khoom siv hluav taws xob sib xyaw ua ke, cov khoom siv kho qhov muag yog cov khoom siv tsis sib xws nyob rau hauv qeb ntawm cov khoom tseem ceeb ntawm cov khoom siv optoelectronic.Cov khoom siv optoelectronic xws li lasers, detectors thiab lwm yam.

Raws li cov ntsiab lus tseem ceeb ntawm cov khoom siv optoelectronic xws li lasers / detectors, optical nti yog qhov tseem ceeb ntawm kev sib txuas lus kho qhov muag niaj hnub no.Niaj hnub nimno kho qhov muag kev sib txuas lus system yog ib tug system uas siv kho qhov muag teeb liab raws li cov ntaub ntawv nqa thiab kho qhov muag fiber raws li ib tug kis tau tus mob nruab nrab rau xa cov ntaub ntawv los ntawm electro-optical conversion.Los ntawm cov txheej txheem ntawm kev xa cov teeb liab, ua ntej ntawm tag nrho cov, qhov kawg xa tawm yog hloov hluav taws xob-kho qhov muag los ntawm cov khoom siv kho qhov muag hauv lub laser, hloov cov teeb liab hluav taws xob rau hauv cov teeb liab kho qhov muag, uas tau xa mus rau qhov kawg tau txais los ntawm fiber ntau optical, thiab tau txais kawg nqa tawm photoelectric hloov dua siab tshiab los ntawm optical nti nyob rau hauv lub detector, converting lub optical teeb liab mus rau hauv hluav taws xob teeb liab.Ntawm lawv, cov tub ntxhais photoelectric hloov dua siab tshiab muaj nuj nqi yog paub los ntawm laser thiab optical nti nyob rau hauv lub detector (laser nti / ntes nti), thiab lub optical nti ncaj qha txiav txim siab ceev thiab kev ntseeg siab ntawm cov ntaub ntawv kis tau tus mob.

Daim ntawv thov scenario

Los ntawm qhov kev xav ntawm ntau qhov kev thov tshwj xeeb, lub laser nti, uas tsim cov photons los ntawm electron leaps, piv txwv li, npog ntau yam.Raws li nws siv cov tiam photon, nws muaj peev xwm muab faib ua lub zog photons, cov ntaub ntawv photons thiab tso saib photons.Daim ntawv thov scenarios ntawm lub zog photon koom nrog fiber ntau laser, kev kho mob zoo nkauj, thiab lwm yam. Daim ntawv thov scenarios ntawm cov ntaub ntawv photon muaj xws li kev sib txuas lus, nws pib autopilot, xov tooj ntawm tes lub ntsej muag paub, kev lag luam tub rog, thiab lwm yam. Cov ntawv thov scenarios ntawm cov duab photon muaj xws li laser teeb, laser TV. , auto headlights, thiab lwm yam.

Kev sib txuas lus kho qhov muag yog ib qho tseem ceeb tshaj plaws ntawm kev siv cov khoom siv kho qhov muag.Optical chips nyob rau hauv kev sib txuas lus kho qhov muag tag nrho tuaj yeem muab faib ua ob pawg: nquag thiab passive, thiab tuaj yeem muab faib ntxiv los ntawm kev ua haujlwm thiab lwm qhov ntev.Raws li kev ua haujlwm ntawm cov chips nquag, lawv tuaj yeem muab faib ua laser chips rau emitting lub teeb liab, ntes chips rau tau txais lub teeb liab, modulator chips rau modulating teeb liab, thiab lwm yam. , AWG chips, VOA chips, thiab lwm yam., uas yog raws li cov txheej txheem kho qhov muag waveguide tshuab los tswj kev sib kis ntawm qhov muag.Kev pom dav dav, lub laser nti thiab ntes nti yog siv ntau tshaj plaws, feem ntau cov tub ntxhais ob hom optical chips.

Los ntawm kev lag luam saw, kev lag luam kev sib txuas lus kho qhov muag kom nrawm rau hauv cheeb tsam ntawm lwm txoj hauv kev los ntawm cov dej ntws mus rau cov dej ntws tawm, cov dej ntws ntws raws li "caj dab" txuas mus rau qhov xav tau ceev nrooj rau qhov tob ntxiv ntawm lwm txoj hauv kev.Cov neeg muag khoom ntawm cov khoom siv qis uas sawv cev los ntawm Huawei thiab ZTE twb yog cov thawj coj hauv kev lag luam, thaum lub chaw kho qhov muag tau ua tiav sai sai ntawm kev hloov pauv hauv cheeb tsam hauv kaum xyoo dhau los los ntawm kev cia siab rau cov nyiaj ntxiv engineer, cov nyiaj tau los thiab cov khoom siv tau zoo.

Raws li Lightcounting cov txheeb cais, tsuas yog ib tus neeg muag khoom hauv tsev yog nyob ntawm 10 sab saum toj hauv 2010, thiab los ntawm 2021, 10 tus neeg muag khoom hauv tsev sab saum toj tau tuav ib nrab ntawm kev ua lag luam.Nyob rau hauv sib piv, txawv teb chaws optical module manufacturers yog maj nyob rau hauv ib tug tsis zoo nyob rau hauv cov nqe lus ntawm kev ua hauj lwm nqi thiab muab saw zoo meej, thiab yog li tsom ntau rau high-end optical pab kiag li lawm thiab upstream optical chips nrog ntau dua qhov pib.Nyob rau hauv cov nqe lus ntawm optical chips, tam sim no high-end cov khoom tseem yog nyob rau hauv txawv teb chaws, tag nrho lub zog ntawm domestic manufacturers thiab txawv teb chaws cov thawj coj tseem muaj qhov sib txawv.

Zuag qhia tag nrho, los ntawm qhov kev xav ntawm cov khoom, tam sim no 10G thiab cov khoom qis qis hauv qab no muaj cov qib siab ntawm kev tsim khoom hauv tsev, 25G muaj cov neeg tsim khoom me me tuaj yeem xa tawm hauv ntau, ntau dua 25G hauv kev tshawb fawb lossis kev sim me me. ntau lawm theem, nyob rau hauv xyoo tsis ntev los no lub taub hau manufacturers nyob rau hauv lub tshav pob ntawm high-end khoom kom ceev cov kev vam meej ntawm pom tseeb.Los ntawm qhov kev xav ntawm daim ntawv thov, cov tuam txhab lag luam hauv tsev tam sim no hauv kev lag luam kev sib txuas lus, kev siv fiber ntau optic thiab wireless nkag mus rau qib siab dua ntawm kev koom tes hauv kev ua lag luam, thaum nyob rau hauv high-end xav tau-oriented cov ntaub ntawv kev sib txuas lus lag luam kuj tau pib nrawm.

Los ntawm qhov kev xav ntawm epitaxial muaj peev xwm, txawm hais tias cov tuam txhab tsim hluav taws xob hauv tsev ntawm laser chip core epitaxial thev naus laus zis tag nrho tseem muaj chaw ntxiv rau kev txhim kho, high-end epitaxial wafers tseem yuav tsum tau yuav los ntawm thoob ntiaj teb epitaxial factories, tab sis tib lub sijhawm kuj tuaj yeem pom. ntau thiab ntau optical nti manufacturers pib ntxiv dag zog rau lawv tus kheej epitaxial muaj peev xwm, pib IDM hom kev loj hlob.Yog li ntawd, kev muaj peev xwm los tsom rau cov khoom lag luam high-end hauv tsev hloov pauv, nrog kev ywj pheej epitaxial tsim thiab kev npaj muaj peev xwm rau IDM hom kev loj hlob ntawm cov tuam txhab tsim khoom hauv tsev nrog cov txiaj ntsig zoo sib tw yuav tsum ua kom muaj kev txhim kho tseem ceeb, nrog rau cov khoom lag luam siab rau qhib kev hloov pauv hauv tsev & digital nkag mus rau thaj chaw pib, xav kom qhib qhov chaw loj hlob yav tom ntej.

Ua ntej, los ntawm cov khoom taw tes ntawm view, 10G thiab cov nram qab no low-end chip domestic hloov mus rau qhov tob, qhov degree ntawm localization tau siab dua.Cov tuam txhab tsim khoom hauv tsev tau paub txog cov thev naus laus zis thev naus laus zis ntawm 2.5G thiab 10G cov khoom, tshwj tsis yog qee cov qauv ntawm cov khoom (xws li 10G EML laser chip) qhov chaw hauv cheeb tsam yog qhov qis, feem ntau ntawm cov khoom muaj peev xwm ua tiav qhov chaw hloov chaw.
