Nws txoj haujlwm ua haujlwm yog ua raws txuas ntawm txuas ntawm semiconductor lub teeb {} em {{} em} em} em} em} em} em} em} em} em} em} em} em} em} em} em} em} em} em} em} em} em} em} em} em} em} em} em} em} em {} em} em} em} em} em} em} em} em} em} em} em} em} em} em} em} em {} em} em} em} em} em} em} em} em} em} em} em} em {} em} em} em} em} em} em} em {} em} embers {} em} em {} em} em} Embers { Laser Diodes tau siv dav hauv qhov siab- ceev kho qhov muag kev sib txuas lus vim lawv lub siab ci, nqaim kab, thiab muaj zog directivity. Lub teeb - emnitting diodes, ntawm qhov tod tes, ua si lub luag haujlwm luv thiab hnov tau vim lawv lub zog tsis tshua muaj zog thiab kav ntev.
Tus yuam sij rau fiber - optic teeb cov lus dag hauv kev ua tiav ntawm lub teeb pom kev zoo hauv kev ua tiav ntawm lub peev txheej thiab lub zog kho qhov muag kom txo tau cov khoom siv hluav taws xob. Tib cov hau kev txuas nrog kev txuas ncaj qha, lens coupling, txhua tus xav tau kho qhov tsim kho kho qhov muag raws li cov kev thov tshwj xeeb.
Cov txheej txheem txuj ci tseem ceeb rau cov khoom siv fiber ntau
1. Semiconductor laser diode (LD) fiber ntau thev naus laus zis
Lemiconductor laser diodes yog cov feem ntau siv teeb pom kev zoo hauv fiber - optic kev sib txuas lus. Lawv cov kev saib xyuas hluav taws xob feem ntau yog feem ntau nyob rau hauv lub ze- Infrared (piv txwv, 15}} {{8} {8 {8} {8} Cov ntaub ntawv muaj peev xwm sib kis. Yuav kom ua tiav kev sib txuas tau zoo, cov hauv qab no yog siv:
Txuas ncaj qha: Lub Laser Diode lub teeb - emitting nto yog kom nruj nreem nrog lub ntsej muag fiber ntau qhov kev sib kis tau zoo. Hom qauv no muaj ib tus qauv yooj yim tab sis yuav tsum muaj cov txheej txheem siab uas tsis tshua muaj qhov tseeb, feem ntau xav tau cov nplua me me {}} tuning mechanism.
Lens Coupling: lasers yog collimated thiab tsom siv tus kheej -} lub lens los txhim kho conving kev ua tau zoo. Cov qauv no txo cov kev sib tw sib txawv tab sis nce kev nyuaj siab.
Microlens array Coupling: Siv tau rau ntau- channel fiber ntau dua, microlens hla kev sib txuas ua ke thiab muaj kev sib faib ua ke ntau yam (WDM) cov tshuab.
2. Fiber Ntau Technology
Fiber ntau siv kho qhov muag roj doped nrog lub ntiaj teb tsawg (xws li erbium, ytterbium, thiab neodymium) raws li qhov nruab nrab. Lub qhov teeb ci (xws li 980 nm lossis 1480 nm laser diode) stiming} pa {}} Cov zis tawm Laser. Cov thev naus laus zis muaj xws li:
Muab ob npaug -} clad fiber ntau cov qauv roj teeb, thaum lub hauv paus sab hauv txhawb ib leeg {}} hom laser tso tawm. Cov lasers no yog qhov tsim nyog rau kev lag luam lag luam thiab siab {5} {ere} Lub zog laser apps.
Cov txheej txheem Raman Fiber Ramers: Raws li cov txheej txheem Raman ua haujlwm, lawv ua tiav rau kev ua haujlwm ntawm kev ua haujlwm tshwj xeeb hauv kev ua haujlwm hauv kev ua haujlwm tshwj xeeb (xws li 1450-1600 nm).
3. Fiber amplifier thiab lub chaw tsim hluav taws xob
E5 -}} doped fiber ntau amplify tshaj tawm hauv fiber ntau, txo qhov xav tau ntawm cov rov qab. Ib qho ntxiv, kev sib xyaw ua ke nrog cov peev txheej nrog cov amplifiers (xws li faib cov lus tawm tswv yim lasers + muaj peev xwm txhim kho kev sib xyaw ntxiv thiab kev ruaj khov.
Cov ntawv thov ntawm fiber - optic lub teeb ci
Fiber - optic teeb cov chaw ua si ib txoj haujlwm Irreplacable txoj haujlwm hauv ntau thaj teb:
Kev sib txuas lus kho qhov muag: high - ceev fiber- Qhov kev sib txuas lus zoo ntawm lub teeb lub teeb. Piv txwv li, tus nqi sib kis ntawm 100 GBPS thiab tshaj kom nqaim-} - chirp laser cov khoom.
Fiber - Qhov kev pom zoo: Muab cov fiber ntau dua thiab cov teeb meem optic
Kho mob thiab muaj: high {- rasers fiber ntau} vuam kev phais, muab qhov zoo ntawm cov kev ua kom zoo thiab tsis muaj kev puas tsuaj.
