Yuav ua li cas siv semiconductor optical amplifier

Txoj kev siv ntawmsemiconductor optical amplifier(SOA) yog raws li nram no:

SOA semiconductor optical amplifier yog dav siv hauv txhua qhov chaw ntawm lub neej. Ib qho ntawm cov kev lag luam tseem ceeb tshaj plaws yog kev sib txuas lus, uas muaj nuj nqis nyob rau hauv routing thiab switching.SOA semiconductor optical amplifierNws kuj yog siv los txhim kho lossis nthuav tawm cov teeb liab tawm ntawm kev sib txuas lus fiber ntau nyob deb thiab yog ib qho tseem ceeb heev optical amplifier.

Cov kauj ruam siv yooj yim

Xaiv qhov tsim nyogSOA optical amplifier: Raws li cov xwm txheej tshwj xeeb thiab cov kev xav tau, xaiv SOA optical amplifier nrog rau qhov tsis zoo xws li kev ua haujlwm wavelength, nce, saturated tso zis hluav taws xob, thiab lub suab nrov. Piv txwv li, nyob rau hauv optical kev sib txuas lus systems, yog hais tias lub teeb liab amplification yuav tsum tau nqa tawm nyob rau hauv lub 1550nm band, ib tug SOA optical amplifier nrog ib tug kev khiav hauj lwm wavelength ze rau qhov ntau yam yuav tsum tau xaiv.

Txuas txoj kev kho qhov muag: Txuas cov tswv yim kawg ntawm SOA semiconductor optical amplifier mus rau qhov chaw kho qhov muag uas yuav tsum tau ua kom muaj suab nrov, thiab txuas cov zis kawg mus rau txoj kev kho qhov muag tom ntej lossis kho qhov muag. Thaum sib txuas, xyuam xim rau kev sib txuas ua haujlwm ntawm cov khoom siv kho qhov muag thiab sim ua kom txo qis qhov muag pom. Cov khoom siv xws li fiber ntau optic couplers thiab optical isolators tuaj yeem siv los ua kom zoo dua kev sib txuas ntawm qhov muag.

Teem qhov kev tsis ncaj ncees tam sim no: Tswj qhov nce ntawm SOA amplifier los ntawm kev kho nws qhov tsis ncaj ncees tam sim no. Feem ntau hais lus, qhov ntau dua qhov kev tsis ncaj ncees tam sim no, qhov nce siab dua, tab sis tib lub sijhawm, nws yuav ua rau muaj suab nrov thiab kev hloov pauv ntawm lub zog tso zis ntau dua. Qhov tsim nyog bias tus nqi tam sim no yuav tsum tau pom raws li qhov yuav tsum tau ua tiag tiag thiab qhov ua tau zoo ntawm kev ua haujlwmSOA amplifier.

Kev saib xyuas thiab kev hloov kho: Thaum lub sijhawm siv cov txheej txheem, nws yog ib qho tsim nyog los saib xyuas qhov tso zis hluav taws xob kho qhov muag, nce, suab nrov thiab lwm yam tsis zoo ntawm SOA hauv lub sijhawm. Raws li kev soj ntsuam cov txiaj ntsig, qhov kev tsis ncaj ncees tam sim no thiab lwm yam tsis zoo yuav tsum tau hloov kho kom ntseeg tau tias kev ua haujlwm ruaj khov thiab teeb liab zoo ntawm SOA semiconductor optical amplifier.

Kev siv nyob rau hauv ntau daim ntawv thov scenarios

Optical kev sib txuas lus system

Lub hwj chim amplifier: Ua ntej cov teeb liab kho qhov muag raug xa mus, SOA semiconductor optical amplifier tau muab tso rau ntawm qhov kawg xa mus ua kom lub zog ntawm cov teeb liab kho qhov muag thiab txuas ntxiv kev sib kis ntawm qhov system. Piv txwv li, nyob rau hauv kev sib txuas lus kho qhov muag fiber ntau nyob deb, amplifying optical signals los ntawm SOA semiconductor optical amplifier yuav txo tau tus naj npawb ntawm relay chaw nres tsheb.

Kab amplifier: Hauv cov kab xaim kho qhov muag, SOA tau muab tso rau ntawm qee lub sijhawm los them rau qhov poob los ntawm fiber ntau attenuation thiab connectors, kom ntseeg tau qhov zoo ntawm optical signals thaum lub sij hawm ntev kis tau tus mob.

Preamplifier: Thaum kawg tau txais, SOA tau muab tso rau pem hauv ntej ntawm tus neeg txais kev kho qhov muag ua lub preamplifier los txhim kho tus neeg txais kev xav thiab txhim kho nws lub peev xwm nrhiav kom pom cov teeb liab tsis muaj zog.

2. Optical sensing system

Nyob rau hauv fiber ntau Bragg grating (FBG) demodulator, SOA boosts lub teeb liab kho qhov muag rau FBG, tswj cov kev taw qhia ntawm lub teeb liab optical los ntawm ib tug circulator, thiab paub qhov kev hloov nyob rau hauv lub wavelength los yog lub sij hawm ntawm lub optical teeb liab tshwm sim los ntawm kub los yog strain variations. Nyob rau hauv lub teeb pom kev thiab ntau yam (LiDAR), nqaim band SOA optical amplifier, thaum siv nrog DFB lasers, tuaj yeem muab lub zog tso zis siab rau kev tshawb nrhiav ntev.

3. Kev hloov pauv wavelength

Kev hloov pauv wavelength yog ua tiav los ntawm kev siv cov teebmeem nonlinear xws li cross-gain modulation (XGM), cross-phase modulation (XPM), thiab plaub-yoj sib xyaw (FWM) ntawm SOA optical amplifier. Piv txwv li, nyob rau hauv XGM, ib tug tsis muaj zog nruam nruam nrhiav pom lub teeb beam thiab lub zog twj tso kua mis teeb beam yog ib txhij txhaj rau hauv SOA optical amplifier. Lub twj tso kua mis yog modulated thiab siv rau lub teeb pom kev los ntawm XGM kom ua tiav wavelength hloov dua siab tshiab.

4. Optical mem tes generator

Nyob rau hauv high-speed OTDM wavelength division multiplexing kev sib txuas lus sib txuas, hom-locked fiber ntau lub nplhaib lasers uas muaj SOA optical amplifier yog siv los ua kom muaj kev rov ua dua tus nqi wavelength-tunable pulses. Los ntawm kev kho qhov tsis zoo xws li kev tsis ncaj ncees tam sim no ntawm SOA amplifier thiab qhov hloov pauv zaus ntawm lub laser, cov zis ntawm optical pulses ntawm txawv wavelengths thiab repetition zaus tuaj yeem ua tiav.

5. Optical moos rov qab

Nyob rau hauv lub OTDM system, lub moos tau zoo rov qab los ntawm kev kub ceev kho qhov muag teeb liab los ntawm theem-locked loops thiab optical switches siv raws li SOA amplifier. OTDM cov ntaub ntawv teeb liab yog txuas rau SOA lub nplhaib iav. Lub optical tswj pulse sequence generated los ntawm adjustable hom-xauv laser tsav lub nplhaib iav. Lub teeb liab tso zis ntawm lub nplhaib iav yog kuaj pom los ntawm photodiode. Qhov zaus ntawm voltage-tswj oscillator (VCO) yog kaw ntawm qhov tseem ceeb zaus ntawm cov ntaub ntawv tawm tswv yim teeb liab los ntawm lub voj voog kaw, yog li ua tiav kev kho qhov muag rov qab.
