Moderi ya electro-optiquenigikoresho cyingenzi cyo guhindura ibimenyetso bya laser bikomeza ukoresheje amakuru, radiyo yumurongo nibimenyetso byamasaha.Inzego zitandukanye za modulator zifite imikorere itandukanye.Binyuze mu buryo bwa optique, ntabwo imbaraga zumucyo zishobora guhinduka gusa, ariko kandi icyiciro na polarisiyasi yumucyo wumucyo birashobora guhinduka.Modulator ikoreshwa cyane na electro-optique ni Mach-Zehndermodulatornaicyiciro.
UwitekaLiNbO3 modulatorikoreshwa cyane muri sisitemu yo gutumanaho yihuta cyane ya sisitemu, laser sensing na sisitemu ya ROF kubera imikorere ya electro-optique.Urukurikirane rwa R-AM rushingiye ku miterere ya MZ yo gukurura no gushushanya X-igabanya, ifite imiterere ihamye yumubiri na chimique, ishobora gukoreshwa haba mubushakashatsi bwa laboratoire ndetse na sisitemu yinganda.

Ibisabwa ku kigereranyo cyo kuzimangana
1. Modulator ya sisitemu igomba kuba ifite igipimo kinini cyo kuzimira.Ibiranga sisitemu modulator ihitamo igipimo ntarengwa cyo kuzimangana gishobora kugerwaho.
2. Polarisiyasi yumucyo winjiza urumuri igomba kwitabwaho.Abayobora bumva polarisiyasi.Gukwirakwiza neza birashobora kunoza igipimo cyo kuzimangana hejuru ya 10dB.Mubigeragezo bya laboratoire, mubisanzwe umugenzuzi wa polarisiyasi arakenewe.
3. Abashinzwe kubogama neza.Mu igeragezwa ryacu rya DC kuzimangana, 50.4dB yo kuzimangana byagezweho.Mugihe datasheet ya modulator ikora urutonde 40dB gusa.Impamvu yiri terambere nuko modulator zimwe zigenda vuba cyane.Rofea R-BC-BURUNDU abayobora kubogama bavugurura bias voltage buri segonda 1 kugirango barebe igisubizo cyihuse.
ROF yibanze kumashanyarazi ya optique hamwe nibigize imyaka icumi.Dukora imikorere-yimikorere ihuriweho-optique kandi itanga ibisubizo bishya hamwe na serivise kubashakashatsi ba siyanse n'abashakashatsi mu nganda.Abayobora moderi ya Rofea hamwe na voltage ntoya hamwe nigihombo gito cyinjijwe byakoreshejwe cyane cyane mukwirakwiza kwant kwinshi, sisitemu ya radio-hejuru ya fibre, sisitemu yo kumva laser, hamwe nibisekuruza bizakurikiraho.
Dutanga kandi modulatrice yihariye yo kwihitiramo, nka 1 * 4 icyiciro cya moderi moderi, ultra-low Vpi, hamwe na moderi ya ultra-high extinction ratio modulator, ikoreshwa cyane cyane muri kaminuza n'ibigo.Byongeye kandi, dukora kandi amplifier ya RF (umushoferi wa modulator) hamwe na BIAS mugenzuzi 、 Photonics detector nibindi.
Mugihe kizaza, tuzakomeza kunoza urutonde rwibicuruzwa bihari, twubake itsinda ryabahanga babigize umwuga, dukomeze guha abakoresha ibicuruzwa byiza, byizewe, ibicuruzwa byateye imbere na serivisi tekinike.
