Txhim kho semiconductor optical amplifier

Txhim khosemiconductor optical amplifier

Qhov txhim kho semiconductor optical amplifier yog ib qho kev hloov kho tshiab ntawm semiconductor optical amplifier (SOA optical amplifier). Nws yog ib qho amplifier uas siv semiconductors los muab qhov nruab nrab nce. Nws cov qauv zoo ib yam li Fabry-Pero laser diode, tab sis feem ntau lub ntsej muag kawg yog coated nrog cov yeeb yaj kiab los tiv thaiv. Cov qauv tsim tshiab tshaj plaws suav nrog cov yeeb yaj kiab tiv thaiv kev cuam tshuam nrog rau cov kev cuam tshuam ntawm lub qhov rooj thiab qhov rais thaj tsam, uas tuaj yeem txo qhov kawg ntawm lub ntsej muag kom qis dua 0.001%. High-performance enhanced optical amplifiers yog tshwj xeeb tshaj yog pab tau thaum amplifying (optical) signals, raws li muaj ib tug loj hem thawj ntawm lub teeb liab poob thaum lub sij hawm ntev kis tau tus mob. Txij li thaum lub teeb liab optical yog ncaj qha amplified, ib txwm txoj kev ntawm converting nws mus rau hauv ib tug hluav taws xob teeb liab ua ntej yuav redundant. Yog li ntawd, kev siv ntawmSOAho txhim kho qhov kis tau tus mob efficiency. Cov tshuab no feem ntau yog siv rau kev faib hluav taws xob thiab kev them nyiaj poob hauv WDM tes hauj lwm.

Daim ntawv thov scenarios

Hauv kev sib txuas lus kho qhov muag fiber ntau, semiconductor optical amplifiers (SOA) tuaj yeem siv rau hauv ntau qhov chaw siv los txhim kho kev ua haujlwm thiab kev sib kis ntawm kev sib txuas lus. Cov hauv qab no yog qee yam kev siv ntawm kev siv SOA amplifier hauv kev sib txuas lus fiber ntau optical:

Preamplifier: SOAoptical amplifiertuaj yeem siv los ua preamplifier ntawm qhov kev txais kho qhov muag kawg hauv kev sib txuas lus ntev nrog cov khoom siv kho qhov muag ntau tshaj 100 mais, txhim kho lossis ua kom lub zog ntawm cov teeb liab tso tawm hauv kev sib txuas lus fiber ntau nyob deb, yog li them nyiaj rau qhov tsis txaus kis tau tus mob los ntawm qhov tsis muaj zog ntawm cov teeb liab me me. Tsis tas li ntawd, SOA tseem tuaj yeem siv los ua kom siv lub tshuab hluav taws xob kho qhov muag rov ua dua tshiab hauv kev sib txuas lus fiber ntau.

All-optical signal regeneration: Nyob rau hauv optical tes hauj lwm, raws li qhov kev ncua deb nce, optical signals yuav deteriorate vim attenuation, dispersion, suab nrov, lub sij hawm jitter thiab crosstalk, thiab lwm yam. Yog li ntawd, nyob rau hauv ntev-kev sib kis, nws yog tsim nyog los them rau cov deteriorated kho qhov muag teeb liab los xyuas kom meej qhov tseeb ntawm cov ntaub ntawv kis tau tus mob. All-optical signal regeneration yog hais txog kev rov ua kom muaj zog, rov ua dua thiab rov ua dua. Kev nthuav dav ntxiv tuaj yeem ua tiav los ntawm optical amplifiers xws li semiconductor optical amplifiers, EDFA thiab Raman amplifiers (RFA).

Nyob rau hauv optical fiber sensing systems, semiconductor optical amplifiers (SOA amplifier) tuaj yeem siv los nthuav cov teeb liab kho qhov muag, yog li txhim kho qhov rhiab heev thiab raug ntawm cov sensors. Cov hauv qab no yog qee qhov kev siv siv SOA hauv optical fiber sensing systems:

Kev ntsuas qhov muag fiber ntau: Kho qhov muag fiber ntau ntawm cov khoom uas nws yuav tsum tau ntsuas. Thaum cov khoom raug strained, qhov kev hloov pauv ntawm cov kab mob yuav ua rau muaj kev hloov me ntsis ntawm qhov ntev ntawm cov khoom siv kho qhov muag, yog li hloov lub wavelength los yog lub sij hawm ntawm lub teeb liab optical rau PD sensor. SOA amplifier tuaj yeem ua tiav qhov kev paub zoo dua los ntawm kev nthuav dav thiab ua cov teeb liab kho qhov muag.

Kev ntsuas qhov muag fiber ntau: Los ntawm kev sib txuas cov khoom siv kho qhov muag nrog cov ntaub ntawv siab-rhiab, thaum ib qho khoom raug rau siab, nws yuav ua rau muaj kev hloov pauv ntawm qhov muag tsis pom nyob rau hauv cov khoom siv kho qhov muag. SOA tuaj yeem siv los nthuav tawm qhov tsis muaj zog kho qhov muag teeb liab kom ua tiav qhov ntsuas siab siab.

Lub semiconductor optical amplifier SOA yog ib qho khoom siv tseem ceeb hauv kev sib txuas lus ntawm fiber ntau thiab optical fiber sensing. Los ntawm kev nthuav dav thiab ua cov teeb liab kho qhov muag, nws txhim kho qhov kev ua tau zoo thiab kev nkag siab rhiab heev. Cov ntawv thov no yog qhov tseem ceeb rau kev ua tiav high-speed, ruaj khov thiab txhim khu kev qha optical fiber kev sib txuas lus nrog rau qhov tseeb thiab muaj txiaj ntsig optical fiber sensing.
