Multimode Polarization Insensitive Isolator
Ib qho optical isolator (tseem hu ua Faraday isolator) yog magneto -optical device uas nyiam xa lub teeb nyob rau hauv ib qho kev taw qhia thaum nqus lossis hloov lub teeb rov qab. Nws tuaj yeem tiv thaiv lub teeb ci los ntawm kev rov qab xav txog thiab teeb liab cuam tshuam, tsis txhob siv lub suab nrov thiab kev puas tsuaj ntawm qhov muag.
Ib qho kev sib cais kho qhov muag feem ntau muaj peb yam tseem ceeb, uas yog,input polarizer, Faraday rotator, thiabtso zis polarizer (tseem hu ua analyzer). Lub hom phiaj yog kom tso cai rau lub teeb ci ntsa iab kom nthuav dav rau pem hauv ntej thiab thaiv hauv qhov sib txawv.
Piv nrog ib zaug xwb -stage isolator, dual-stage isolator muaj ntxiv Faraday rotator, ib nrab nthwv dej phaj, thiab ob chav reflection beam shifter kom ua tiav kev sib cais ntau dua. Ib leeg-stage isolator yog qhov zoo rau cov tshuab uas muaj teeb pom kev cuam tshuam tsawg dua, xws li kev sib txuas lus zoo tib yam, qis- lub teeb hluav taws xob tiv thaiv, lub teeb ci pem hauv ntej- kev tiv thaiv kawg, thiab cov tshuab hloov kho yooj yim. Dual-stage isolator yog qhov tsim nyog rau cov tshuab uas tshwj xeeb tshaj yog rau kev xav lossis xav tau kev sib cais siab heev.
Optico muab cov series ntawm polarization insensitive isolators nrog ntau lub wavelengths, nrog rau 1310nm / 1480nm / 1550nm thiab L-band multi-mode qauv. Multimode polarization insensitive isolators feem ntau yog siv rau siab -lub zog laser tiv thaiv, nrog lub zog ua haujlwm siab thiab qhov chaw kam rau siab. Lawv qhov sib txuas yooj yim thiab kev ua txhaum siab siab kuj ua rau lawv cov teeb liab ruaj khov dua li -mode polarization cais tawm thaum lub sijhawm ua haujlwm.
(Ntau qhov tshwj xeeb wavelength hauv cov ntaub ntawv txuas nrog)
Qhov sib txawv ntawm ib leeg -theem thiab dual-stage optical isolators
--- Kev rho tawm theem: Ib hom kev cais ib leeg ib leeg feem ntau yog nyob nruab nrab ntawm 30-35dB, thaum dual-theem cais yog nyob nruab nrab ntawm 45-55dB
--- Insertion poob: Ib theem isolator 0.3 ~ 0.5dB, thaum dual-theem 0.5 ~ 0.8dB, siab dua me ntsis
--- Optical zog: Ib leeg cais muaj hwj chim qis dua, thaum dual-theem muaj siab dua. Dual-theem yog tsim nyog rau cov tshuab hluav taws xob siab
--- Tus nqi: Dual-stage isolator kim dua, cov neeg siv yuav tsum xaiv raws li qhov yuav tsum tau ua thiab pob nyiaj siv
Isolators ua haujlwm li cas
Thaum nyob rau hauv kev siv, lub teeb liab tawm los ntawm lub input polarizer. Lub input polarizer thaiv lub teeb pom kev ntawm orthogonal polarization thaum tso cai rau lub teeb pom kev ntawm ib qho tshwj xeeb polarization los ntawm nws. Lub teeb liab ces nkag mus rau Faraday rotator. Nyob ntawd lub teeb teeb liab yog tig los ntawm lub kaum sab xis zoo li 45 degree. Qhov kev sib hloov no tsis yog -reciprocal. Lub teeb liab tau txais kab rov tav polarized tom qab kev sib hloov ntawm polarization. Thaum lub teeb liab kab rov tav polarized no tau tshwm sim nyob rau hauv qhov kev taw qhia rov qab, lub tswv yim polarizer, ua ib lub polarizer ntsug, tsis kam lees nws. Thaum kawg, tsuas yog lub forwar - taw qhia lub teeb qhia tau los ntawm cov zis polarizer.
