VCSEL laser(Ntsug Cavity Nto Kho Qhov Muag Laser)
Lub npe tag nrho ntawm VCSEL yog Ntsug Cav Ntxig Ntev Sab Ua Haujlwm Laser (VCSEL), uas yog hu ua laser-saum npoo. Nws yog ib qho ntawm lub teeb pom kev zoo siv hauv kev sib txuas lus fiber ntau.
Lub npe tag nrho ntawm VCSEL yog Ntsug Cav Ntxig Ntev Sab Ua Haujlwm Laser (VCSEL), uas yog hu ua laser-saum npoo. Nws yog ib qho ntawm lub teeb pom kev zoo siv hauv kev sib txuas lus fiber ntau. Txawv los ntawm LED (Lub Teeb Emitting Diode) thiab lwm lub teeb pom kev zoo xws li LD (Laser Diode), VCSEL hom teeb ci tuaj yeem hloov qhov zaus mus rau Giga Hz, thiab tus nqi sib kis ib txwm muaj Giga bps. Txawm hais tias cov LDs ua pa tseem muaj cov yam ntxwv saum toj no, lawv kim dua thiab qhov ua kom zoo ntawm luminescence tseem phem dua VCSEL. Tsis tas li ntawd, qhov kev tsav tsheb voltage thiab tam sim no yuav tsum tau los ntawm VCSEL yog qhov me me, yog li lub neej ua haujlwm ntau dua 10 lab teev, ntau dua 100 npaug ntawm lwm cov teeb ci. OPEAK module / desktop VCSEL qhov khoom muaj qhov siab ruaj khov, tus nqi tsim nyog ntawm lub teeb ci. Caw kaw lus tshwj xeeb kev tswj qhov kub thiab txias (ATC) thiab cov tswj hwm lub zog (APC) kom paub tseeb tias kev ua kom ntev ntawm kev ruaj ntseg ntawm lub zog kho qhov muag thiab cov duab zoo nkauj. Tib hom fiber ntau cov zis, ntau yam kev txuas lossis cov hloov khoom siv tau los pab ceev ceev, poob qis, txuas nrawm nrog cov cuab yeej sab nraud. Lub tso zis hluav taws xob hloov kho tau yog kho tau thiab sab hauv cov kev hloov kho hom yog xaiv tau.
Ntsia kab noj hniav ntsug emitting laser (VCSEL) yog ib yam tshiab ntawm cov laser uas tso tawm lub teeb los ntawm ib feem ntsug. Tus qauv sib txawv ntawm cov lus tshaj tawm ntawm cov npoo laser coj tau ntau yam zoo: qhov sib txawv me me lub kaum ntse ntse thiab cov kab sib txig sib luag ntawm qhov chaw nyob deb thiab ze ze ua kom muaj kev sib txuam ntau ntxiv nrog cov fiber ntau yam tsis muaj qhov nyuaj thiab kim nqaj tsim cov kab ke. Nws yog qhov ua pov thawj tias kev sib txuam nrog cov roj carbon fiber ntau yuav ua tau ntau dua 90%; qhov ntev ntawm cov kab noj hniav yog tsis tshua muaj luv, uas ua rau lub hom loj ntev ntawm qhov sib txawv, uas tuaj yeem paub qhov ntev ib hom kev ua haujlwm nyob rau hauv qhov chaw kub ntau, thiab qhov hloov pauv hloov pauv tau siab; Me me ua rau nws qhov tshwm sim emission tau ntau qhov kev txiav txim ntawm qhov ntau dua qhov muaj peev xwm tshaj li qhov tseeb lub qhov cub uas muaj qhov kawg, uas ua rau ntau qhov chaw ntawm lub cev tau raug hloov kho; tuaj yeem raug sim hauv cov nti, uas zoo heev txo tus nqi txhim kho; qhov kev taw qhia ntsug ntawm lub teeb taw qhia ua rau nws yooj yim kom ua tiav qhov ntom ntom. Kev sib xyaw ntawm ob thaj tsam ntawm cheeb tsam muaj peev xwm ua kom lub zog tso zis ntau dua, thiab vim tias ntau lub lasers tuaj yeem muab cov kab hluav taws xob tso rau hauv cov kev taw qhia sib luag mus rau qhov chaw hla, nws tau zoo rau cov kev siv xws li cov kab hluav taws xob sib txuas thiab kev sib txuas optical kho qhov muag. Cov nrawm yog ua tiav rau ib leeg-channel thiab cov kab sib txuas kho qhov muag sib txuas, nrog nws cov txiaj ntsig kev ua tau zoo-tus nqi sib piv hauv qhov dav dav Ethernet thiab cov kev sib txuas lus cov ntaub ntawv xov xwm sib txuas. Txhawm rau ntau ntawm cov ntawv thov; nws yog cov txheej txheem tsim kom zoo nkauj tshaj plaws ntawm lub teeb hluav taws xob tso tawm (LED) sib xws, tsawg tus nqi tsim khoom.
Daim ntawv thov thiab kev cia siab:
Hais txog kev sib txuas lus fiber ntau, VCSEL kev lag luam tam sim no tab tom tsim ntawm qhov tsis tau pom dua, thiab kev hloov pauv ntawm cov nqi hluav taws xob LDs hauv North America rau kev tsim kho Gigabit thiab 10 Gigabit Ethernet cov ntaub ntawv sib txuas lus sib txuas tau ua rau muaj kev loj hlob nyob rau hauv thov rau kev kub ceev VCSEL transceiver modules. Txawm hais tias kev lag luam kev sib txuas lus tam sim no tsawg zuj zus, raws li kev kwv yees tsis ntev los no los ntawm E1ectroniCast, qhov kev thov thoob ntiaj teb rau VCSEL laser transceivers rau kev sib txuas lus optical yuav txuas ntxiv nce ntxiv ntawm tus nqi ntawm 35% hauv ib xyoos nyob rau tsib xyoos tom ntej, nce mus txog $ 2 txhiab los ntawm 2006. Yav tom ntej Tuam Tshoj yuav yog qhov loj tshaj plaws kev sib txuas lus network kev ua lag luam, siv VCSEL / Pin arrays kom ua tiav qhov chaw luv heev (VSR) thaum sib tw ua qhov muag sib txuas ntawm 10 Gbit / s lossis txawm 40 Gbit / s thiab high-density rov qab nruab nrab ntawm cov cuab yeej hloov loj thiab cov khoom siv sib kis. Pawg thawj coj saib kev kawm yuav txhawb nqa qhov kev loj hlob ntawm cov ntaub ntawv kev sib txuas lus hauv tsev thiab kev sib txuas lus.
VCSEL kuj tseem muaj cov ntawv thov zoo nyob rau lwm qhov. Hais txog kev luam tawm kho qhov muag, kev lag luam hluav taws xob ntawm lub teeb tsa cov duab thaij duab zoo li lub teeb tsom polygonal hauv lub tshuab luam ntawv laser tau raug teeb meem uas tsis tau daws tau ntau xyoo, thiab maj mam txhim kho nrog kev txhim kho thev naus laus zis. Yog tias siv LED arrays, kev siv hluav taws xob yog qhov teeb meem, thiab kev qhia ntawm VCSEL arrays tuaj yeem daws qhov teeb meem no. Ntau nqaj nyob rau hauv daim ntawv ntawm ib qho ntawm ib qho phav phav ntawm VCSELs tej zaum yuav yog txoj kev zoo tshaj plaws los hloov duab tsom iav polygonal. Muab piv rau cov roj laser hluav taws xob yav dhau los, VCSEL' s array-integrated qauv tso cai rau kev sib txuam ntau cov kab txuas. Qhov no muaj peev xwm nce ntau ntawm kev nrawm ntawm lub laser luam ntawv thiab txuas ntxiv nws lub neej kev pab. Hauv kev hais txog lub teeb pom kev zoo, cov ntawv ib txwm siv tau tsim siv liab, ntsuab, thiab xiav ternary xim lub teeb xim. Yog tias cov lasers nrog xim liab, ntsuab, thiab xiav ternary xim tuaj yeem tsim tau, lawv tuaj yeem siv rau hauv cov txuj ci kev ua haujlwm ntawm cov ntawv loj. Cov. Tam sim no, GaN series lasers nrog wavelengths txij li xiav mus rau ultraviolet yog nyob rau hauv kev tshawb fawb theem. Qhov ntu no ntawm VCSELs yog lub thev naus laus zis muaj zog rau kev daws teeb meem cov duab yav tom ntej. Hais txog qhov ua kom pom tseeb, qhov hloov pauv ntawm electro-optic efficiency ntawm VCSEL yog ntau dua 50%, uas yog ntau dua tshaj qhov tam sim no illumination qhov chaw. Yog hais tias nws txoj kab hluav taws xob tuaj yeem npog los ntawm ultraviolet thaj tsam mus rau thaj chaw pom, nws tuaj yeem cia siab kom muaj kev thov dav dav hauv lub tshav pob ntawm lub teeb pom kev zoo. Yuav kom ua tiav lub teeb pom kev dawb. Piv txwv li, teeb pom kev zoo sab hauv tsev uas kho cov teeb pom kev zoo, lub teeb nraub qaum rau lub laptop, teeb pom kev zoo, thiab cov teeb pom kev sab nraum zoov Tsis tas li ntawd, tseem muaj kev cia siab rau daim ntawv thov nyob rau hauv kev kuaj xyuas roj thiab cov khoom siv kho qhov muag-kom ceev.
