Yuav ua li casSemiconductor Optical AmplifierUa tiav qhov amplification?
Tom qab kev tawm tsam ntawm lub caij nyoog ntawm loj-muaj peev xwm kho tshuab fiber ntau, kho qhov muag ua kom zoo dua qub thev naus laus zis tau tsim kho sai.Kho Qhov Kho Kom Zoo NkaujAmplify tawm cov cim qhia tawm raws li kev siv hluav taws xob ntau lossis ua rau muaj kev lom zem. Raws li tus ua haujlwm ua haujlwm, kho kom zoo nkauj tau muab faib ua semiconductor kho qhov zoo tshaj plaws (Soa) thiabKho qhov muag Fiber NtauCov. Ntawm lawv,Semiconductor Kho Kom Zoo Tshajtau siv dav hauv kev sib txuas lus los ntawm kev sib txuas lus los ntawm qhov zoo ntawm kev nce siab loj, kev sib koom ua zoo thiab dav dav dav. Lawv muaj cov cheeb tsam nquag thiab passive, thiab thaj av nquag yog thaj av nce. Thaum lub teeb liab teeb dhau los ntawm thaj av nquag, nws ua rau cov electrons kom poob lub zog thiab rov qab rau lub ntsej muag hauv av, yog li pom lub teeb liab zoo li qub, yog li tawm ntawm lub teeb liab. Lub semiconductor kho qhov muag tshaj plaws los ntawm cov khoom siv rov qab los ntawm cov khoom siv rov qab los ntawm kev txhaj tshuaj ntawm lub teeb pom kev zoo li polarization, kab dav thiab zaus. Nrog rau kev nce ntawm kev ua haujlwm tam sim no, cov tso zis kho qhov muag siv tau kuj tseem nce hauv kev sib raug zoo.
Tab sis txoj kev loj hlob no tsis yog tsis muaj kev txwv, vim semicondor kho qhov muag tshiab tau muaj qhov ua kom zoo dua qub. Qhov tshwm sim uas pom tau tias thaum lub zog tawm siv hluav taws xob tsis tu ncua, tab sis thaum txhaj tshuaj carrier ntau dhau, qhov nce yuav saturate los yog txawm tsawg dua. Thaum lub concentration ntawm cov cab kuj tas mus li, cov zis siv hluav taws xob ntau dhau, tus nqi hloov kho qhov muag tau tshwm sim los ntawm kev kub ntxhov ntau dhau lawm, ua rau muaj kev ruaj khov lossis poob qis. Qhov laj thawj rau qhov tau tshwm sim txaus siab yog qhov kev sib cuam tshuam ntawm cov khoom siv hluav taws xob thiab photons hauv cov khoom siv thaj av. Txawm hais tias lub photons tsim tawm hauv qhov nruab nrab lossis sab nraud sab nraud, tus nqi thaum cov neeg nqa khoom muaj feem xyuam nrog tus nqi uas tus neeg nqa khoom rov qab ua rau lub sijhawm. Ntxiv rau qhov ntsuas hluav taws xob, cov cab kuj tau noj los ntawm lwm yam tseem hloov pauv, uas cuam tshuam rau kev ua kom muaj kev ruaj khov.
Txij li cov haujlwm tseem ceeb tshaj plaws ntawm semiconductor kho qhov muag tshiab, nws tuaj yeem siv ua kom tau cov amplifiers, kab ua kom zoo tshaj plaws thiab preamplifiers hauv cov tshuab sib txuas lus. Ntawm kev xa mus tas li, lub semiconduction kho qhov muag tshaj plaws los txhim kho qhov kawg ntawm lub cev, uas tuaj yeem nce ntxiv cov kev ncua deb ntawm cov kab ke system. Nyob rau hauv kis kab mob, lub semiconductor kho qhov muag tau tuaj yeem siv los ua kab reliferative repay tuaj yeem txuas ntxiv los ntawm kev khiav mus thiab ciam teb. Thaum tau txais kawg, Semiconductor kho qhov muag tau tuaj yeem siv los ua cov preamplifier, uas tuaj yeem txhim kho qhov rhiab ntawm cov tau txais. Qhov tau txais cov yam ntxwv ruaj khov ntawm semiconductor kho qhov muag tshiab yuav ua rau qhov nce ib qho yuav cuam tshuam nrog yav dhau los ua ntu zus. Cov qauv cuam tshuam ntawm cov txheeb me me tseem tuaj yeem hu ua kev hla kev-nce cov nyhuv ntsuas ntsuas. Cov txheej txheem no siv qhov nruab nrab ntawm cov kev sib txawv ntawm ntau cov kwj deg hauv cov nqaj hlau, yog li cacking tag nrho cov kev nce ntawm lub amplifier. Tom qab ntawd cov ntoo khaub lig-nce cov txiaj ntsig kev ua haujlwm ntawm cov kab yog txo.
Semiconductor kho qhov muag tshiab muaj cov qauv yooj yim, kev sib koom ua kom yooj yim, thiab tau siv dav hauv kev sib xyaw ua ke ntawm ntau hom lasers. Tam sim no, kev siv tshuab Laser Laser ua kho qhov muag tshiab txuas ntxiv mus rau kev paub tab, tab sis kev siv zog tseem yuav tsum tau ua li ntawm peb yam hauv qab no. Ib qho yog kom txo cov kev sib txuas nrog cov tshuaj kho qhov muag. Qhov teeb meem tseem ceeb ntawm semiconductor optical amplifier yog tias kev sib txuas ua nrog cov fiber ntau. Txhawm rau txhim kho cov kev ua tau zoo, ib lub lens tuaj yeem raug ntxiv rau lub sib txuas ua kom tsawg, txhim kho cov kab ke ntawm lub nqaj, thiab ua tiav cov nyiaj sib txuam ua ke. Qhov thib ob yog txhawm rau txo cov kev paub txog kev paub txog ntawm semiconductor kho qhov zoo tshaj plaws. Cov neeg muaj txiaj ntsig polarization tsuas yog hais txog cov kev paub txog kev sib tw ntawm qhov xwm txheej teeb. Yog hais tias semiconductor optical amplifier tsis yog tshwj xeeb ua tiav, muaj txiaj ntsig zoo bandwidth ntawm qhov nce yuav raug txo. Quantum tus qauv yuav ua tau zoo txhim kho qhov ruaj khov ntawm semiconductor kho qhov zoo tshaj plaws. Nws yog qhov ua tau los kawm cov qauv yooj yim thiab zoo tshaj plaws kom txo cov kev paub zoo ntawm cov semiconductor kho qhov zoo tshaj plaws. Qhov thib peb yog qhov ua kom zoo ntawm cov txheej txheem sib xyaw. Tam sim no, kev sib koom ua ke ntawm semiconductor kho qhov muag thiab cov khoom lag luam loj hauv kev ua haujlwm ntawm kev ua haujlwm, ua rau muaj teeb meem optical Yog li ntawd, peb yuav tsum sim ua kom zoo rau cov qauv ntawm cov cuab yeej ua ke thiab txhim kho cov khoom siv ua ke.
Hauv kev sib txuas lus kho qhov muag siv kev siv tshuab, kev kho kho kho qhov tshiab yog ib qho ntawm cov thev naus laus zis txhawb kev siv tshuab yog tsim kho kom sai. Tam sim no, kev ua yeeb yam ntawm semiconductor kho qhov muag tshiab tau zoo dua qub, tshwj xeeb hauv kev sib faib tshiab kho kho tshiab lossis hloov kho kho qhov muag. Nrog rau kev txhim kho cov ntaub ntawv kev lag luam, lub tshuab kev siv kho tshiab tsim nyog rau cov kev siv tshuab tshiab yuav ua rau lub semiconductor kho qhov muag tshiab txuas ntxiv txhim kho thiab vam meej.
