Hauv Optical fiber kev sib txuas lus, Optical Hloov (OS) yog tsuas yog siv kom paub lub cev hloov ntawm Optical cov cim los yog lwm cov laj thawj kev ua haujlwm hauv Optical paths, thiab feem ntau siv los ua cov cuab yeej tseem ceeb rau hloov Optical paths hauv THE Optical cross-connect technology.
Cov hloov kho qhov muag tau muaj ib los yog ntau dua kev xaiv sib kis ntawm lub Windows thiab tuaj yeem faib ua 2 × 2, 1 × N thiab M × N chaw nres nkoj teeb tsa. Cov hloov kho qhov muag tau siv dav hauv kev sib txuas lus kho qhov muag fiber ntau, thiab lawv qhov kev paub txog kev siv tshuab yog ntau yam. Mechanical optical hloov thiab MEMS optical hloov yog ob yam ntawm kev sib tw kho qhov muag tau dav siv tam sim no.
Neeg kho tshuab optical hloov
Kev hloov kho cov tshuab qog ua haujlwm los ntawm kev txav ntawm lub cev txav los ntawm cov cuab yeej siv kho qhov muag los hloov cov teeb liab kho qhov muag. Los ntawm txoj kev ib lub prism txav lossis ib qho kev taw qhia cov coupler, lub teeb nkag tau muab tso rau qhov chaw nres nkoj tsim tawm. Muaj peb hom tseem ceeb ntawm cov kev hloov kho ntawm cov khoos phis tawm: prism switching, tsom iav hloov thiab txawb hluav taws xob optical hloov.
MEMS optical hloov
MEMS kho qhov muag hloov kho yog ua raws li Micro-electro-mechanical-system. Nws txais yuav kev tsom iav kho qhov muag los yog cov tsom iav kho qhov muag kom hloov pauv txoj kev coj cov teeb nrig kom pom tseeb txoj kev hloov ntawm txoj kev kho qhov muag. Lub hauv paus ntsiab lus ntawm MEMS optical hloov yog yooj yim heev. Thaum coj kev sib pauv kho qhov muag, lub teeb nkag tuaj yeem hloov mus rau qhov sib txawv ntawm qhov xaus ntawm qhov hloov kho hloov kho los ntawm kev hloov chaw lossis hloov Lub Kaum Ntsej ntawm MEMS micro daim iav uas tau tsav los ntawm electrostatic lossis lub zog sib nqus, yog li kom paub qhov hloov thiab qhib / tawm ntawm txoj kev kho qhov muag Cov. Nws daim duab schematic yog qhia hauv daim duab hauv qab no:
Lub hauv paus ntsiab lus ntawm 2 × 2 chaw nres nkoj kho qhov muag hloov raws MEMS thev naus laus zis yog qhia hauv daim duab. Plaub lub ntsej muag kho qhov muag tau teeb tsa hauv plaub qhov kev taw qhia, thiab feem ntsug MEMS micro tsom iav tau teem rau ntawm 45 ° Lub. Thaum micro tsom iav tsis koom nrog hauv cov kab ke kho qhov muag, cov kab teeb los ntawm waveguide 1 thiab 2 txuas txuas rau waveguide 3 thiab 4 feem, thiab cov chaw nres nkoj sib txuas yog 1 → 3 thiab 2 → 4, uas yog lub xeev ncaj. Thaum lub tsom iav micro tau tso rau hauv txoj kev kho qhov muag, lub teeb ci los ntawm waveguide 1 thiab 2 tau cuam tshuam los ntawm micro daim iav thiab txuas rau cov chaw nres nkoj 4 thiab 3, feem. Cov xeev sib txuas ntawm cov chaw nres nkoj yog 1 → 4 thiab 2 → 3, uas yog cov xeev hla.
Ua haujlwm cov ntsiab lus ntawm 2 port 2 chaw nres nkoj MEMS kho qhov muag, sab laug daim duab: xeev ncaj, daim duab sab xis: hla xeev
Mechanical optical hloov& Kev sib piv ntawm qhov zoo thiab qhov tsis zoo ntawm MEMS optical hloov
Sib piv ntawm qhov zoo thiab qhov tsis zoo | Qhov zoo | Nyias tsis zoo |
Neeg kho tshuab optical hloov | Tsawg poob zoo; Kev rho tawm qib siab yog siab; Nws' s ywj siab ntawm wavelength thiab polarization; Cov txheej txheem ntau lawm thiab thev naus laus zis tau paub tab | Lub sijhawm hloov pauv yog lub sijhawm ntev; Loj ntim tsis yog qhov tsim nyog los ua ib qhov loj tau hloov qhov kev ntsuas qhov ntsuas |
MEMS optical hloov | Cov ntim me me, kev sib koom siab siab; Siab scalability; Tsawg polarization poob; Lub tshuab txais ceev nrawm | Tus nqi siab; Cov txheej txheem ntau lawm thiab cov khoom siv txuj ci siab tau yog siab |
Nrog txoj kev loj hlob sai ntawm kev sib txuas lus kho qhov muag, lub luag hauj lwm ntawm kev sib txuas lus kho qhov muag thiab kev sib hloov kho raws li kho qhov muag network nodes ntau dua thiab tseem ceeb dua, thiab daim ntawv thov ntawm cov khoos phis tawj tau ntxiv thiab dav dua. MEMS optical hloov tau muaj qhov zoo ntawm kev cog lus, hloov mus nrawm nrawm nrawm thiab nthuav yooj yim, thiab muaj qhov zoo ntawm qhov tsis muaj qhov poob qis, tsis tshua muaj crosstab; qis polarization rhiab heev, siab extinction piv thiab waveguide hloov nrog lub siab hloov ceev, ntim me thiab yooj yim loj-teev kev koom ua ke. Nws yuav yog lub qauv tshiab hauv kev txhim kho loj-lub peev xwm hloov kho qhov muag tau hloov kho network.
