Dab tsi yog kev lag luam kev siv ntawmSOA optical amplifiers?
SOAsemiconductor optical amplifieryog PN junction ntaus ntawv siv cov qauv quantum zoo. Kev tsis ncaj ncees sab nraud ua rau muaj kev cuam tshuam ntawm cov pej xeem, thiab lub teeb sab nraud ua rau muaj hluav taws xob ua kom muaj zog, ua rau lub teeb liab optical amplification. Qhov zoo: Txhawb kev kub ceev, siab bandwidth, qis zog noj, siab nce, miniaturization, thiab kev sib koom ua ke yooj yim. Disadvantages: cross-gain modulation thiab nonlinear kev sib cuam tshuam ntawm txawv wavelength raws, polarization rhiab heev, nce saturation. Piv nrog EDFA optical amplifiers (erbium-doped fiber ntau amplifiers), qee qhov ntsuas ntawm cov khoom lag luam tsis muaj zog duaEDFA kho qhov muag amplifiers, mas SOAoptical amplifierstseem muaj cov yam ntxwv uas EDFA optical amplifiers hloov tsis tau. Yog tias nws tuaj yeem txhawb O-band (1260-1360), E-band (1360-1460), L-band (1460-1530) amplification, thiab muaj cov yam ntxwv ntawm tus nqi qis, me me thiab kev sib koom ua ke yooj yim, nyob rau hauv lub tshiab infrastructure era, SOA optical amplifiers yuav nyob rau hauv kev nkag tau network thiab cov ntug ntawm tus txiv neej optical scale, raws li zoo raws li cov ntaub ntawv loj.
Kev lag luam daim ntawv thov ntawm SOA optical amplifier
Nrog rau kev txhim kho kev ua tau zoo ntawm SOA optical amplifier xws li tso zis hluav taws xob kho qhov muag, me me teeb liab nce, nce polarization rhiab heev thiab suab nrov Performance index, SOA amplifier yuav ua lub luag haujlwm tseem ceeb hauv txhua qhov kev sib txuas lus kho qhov muag thiab cov tes hauj lwm sensor. Ntxiv rau SOAoptical amplifiersuas tuaj yeem ua tau raws li qhov kev nthuav dav ntawm 1310 nm band,SOA amplifierstuaj yeem hloov pauv EDFA amplifiers hauv qee qhov ib-theem amplification teb ntawm 1550 nm band.
1. Carrier optical kis tau tus mob network
Nrog rau kev tsim kho ntawm 5G network, qhov kev thov bandwidth surges, thiab 100G (4 * 25G CWDM4 / LWDM4) high-speed kis tau tus mob yuav tsum tau nyob rau ntawm ntug ntawm kev nkag network thiab lub nroog cheeb tsam network, thiab qhov kev ncua deb ntawm ntug ntawm lub nroog thiab lub zos kis tau tus mob, kev nkag network thiab lub nroog cheeb tsam network feem ntau yog 5km-4. Nyob rau hauv 5G lub hauv paus chaw nres tsheb rau pem hauv ntej kis scenario, nyob rau hauv qee lub hauv paus chaw nres tsheb uas nyob deb, kho qhov muag modularSOA ntaus ntawvtuaj yeem siv los txhim kho lub zog kho qhov muag, thiab paub txog kev hloov pauv ntawm lub teeb qis ntawm 25G teeb liab tus nqi ntawm lub hauv paus chaw nres tsheb hauv 1310 nm band thiab 1550 nm band. Nyob rau hauv daim ntawv thov ntawm cov cab kuj network, SOA amplifier tuaj yeem muab tso rau hauv ROSA lossis TOSA ntawmoptical amplifier module, lossis cov khoom siv ywj pheej SOA lossisSOA optical moduletuaj yeem siv rau amplification.
2. Spectral amplification ntawm network xyuas
Tam sim no, nrog rau kev loj hlob sai ntawm cov ntaub ntawv lag luam, qhov kev thov rau cov ntaub ntawv streaming xyuas hauv kev ua lag luam yog maj mam nce, uas feem ntau yog nyob rau hauv cov tub ntxhais network node rau spectral saib, lub teeb liab feem ntau tsis muaj zog, yuav tsum tau siv optical amplifier, thiab 100G lag luam muaj ntau 1310 wavelength, tsuas yog amplified los ntawm SOA ntaus ntawv. Qhov no kuj yog qhov feem ntau siv thiab paub tab daim ntawv thov ntawm SOA amplification tam sim no.
3. DCI rau data center interconnection
Nrog rau txoj kev loj hlob ntawm cov ntaub ntawv loj, qhov kev thov rau siab bandwidth interconnection ntawm cov ntaub ntawv chaw yog maj mam nce. Rau cov kev pabcuam siab ceev, SOA ntaus ntawv tuaj yeem siv rau kev kho qhov muag teeb liab relay amplification, ua rau qhov txuas kho qhov muag lub zog thiab txuas ntxiv qhov sib kis. SOA amplifiers tuaj yeem siv rau ob qho tib si 1310 band thiab 1550 band high-speed kev pab cuam kho qhov muag teeb liab amplification. Qhov kev lag luam no feem ntau siv nyob ib leegSOA semiconductor optical amplifiers(cov khoom siv khib nyiab mounted).
4. Daim ntawv thov ntawm kev faib fiber ntau optic sensing thiab LiDAR system
SOA optical modules muaj cov yam ntxwv zoo tshaj plaws ntawm cov lus teb thiab qhov kev ploj tuag siab, thiab tuaj yeem siv los ua qhov hloov kho qhov muag lossis hloov kho. Nrog rau kev txhim kho txuas ntxiv ntawm SOA thev naus laus zis, AOM modulators tuaj yeem hloov pauv hauv feem ntau ntawm cov khoom siv kho qhov muag kom tau txais nqaim mem tes laser nrog qhov sib piv siab.
Nyob rau hauv xyoo tas los no, nrog rau kev loj hlob sai ntawm kev txawj ntse tsheb tsav tsheb thiab kev sib koom ua ke ntawm tsheb-txoj kev, LiDAR tau siv dav hauv ob lub tsheb-sab thiab txoj kev tsheb. Vim lub miniaturization thiab siab nce ntawmSOA optical amplifier module, nws tuaj yeem siv rau hauv LiDAR kom tau txais nqaim linewidth laser thiab txhim kho lub zog kho qhov muag, tshwj xeeb tshaj yog cov khoom siv kho qhov muag Lidar ntawm cov tiam tom ntej ntawm lub zos FMCW thev naus laus zis, uas yog daim ntawv thov dav dav ntawm yav tom ntej SOA optical amplifier.
