Rau siv hauv ib hom fiber ntau _ yog siv zoo dua. Nqe lus piav qhia: Semiconductor optical amplifiers muaj lub zog siv tsawg. Muaj ib hom qauv ua rau lawv tsim nyog thiab haum rau siv nyob rau hauv ib hom fiber ntau.
Dab tsi yog daim ntawv thov ntawm optical amplifier?
Cov kev siv ntawm optical amplifiers yog: Ib lub amplifier tuaj yeem txhawb nqa lub zog (nruab nrab) ntawm lub laser tso zis mus rau qib siab dua (→ tus tswv oscillator fais fab amplifier=MOPA). Nws tuaj yeem tsim lub zog siab tshaj plaws, tshwj xeeb tshaj yog nyob rau hauv ultrashort pulses, yog tias lub zog khaws cia tau muab rho tawm hauv lub sijhawm luv luv.
Muaj pes tsawg hom optical amplifier technologies muaj?
Muaj 2 hom ntawm cov khoom siv kho qhov muag; OFA (Optical Fiber Amplifier) thiab SOA (Semiconductor Optical Amplifier). Muaj 2 hom OFAs ntxiv; EDFA (Erbium-Doped Fiber Amplifier) thiab FRA (Fiber Raman Amplifier).
Muaj pes tsawg hom kev nthuav tawm muaj nyob hauv ib hom Fibre?
Kev piav qhia: Muaj ob hom kev nthuav tawm hauv ib hom fibers. Ob hom no zoo sib xws tab sis lawv cov dav hlau polarization yog orthogonal. Hauv cov fibers tiag tiag, muaj qhov tsis zoo xws li kev hloov pauv hauv qhov ntsuas qhov ntsuas tsis pom.
Qhov twg optical amplifier muaj qhov zoo dua?
Kev piav qhia: Raws li piv rau txhua qhov kev nthuav dav, Raman amplification yog qhov zoo dua. Nws muaj nws tus kheej-theem kev sib piv ntawm lub twj tso kua mis ntawm lub teeb liab ua ke nrog dav nce bandwidth piv rau lwm cov txheej txheem nonlinear.
