Rof Electro-optic modulator 850 nm electro optic intensity modulator 10G

Igipimo cy'irimbuka rya Maxim DC

Muri ubu bushakashatsi, nta bimenyetso bya RF byakoreshejwe kuri sisitemu. Pure DC extinciton yarapimwe.
1. Ishusho ya 5 igaragaza imbaraga z'urumuri rw'amashanyarazi (optical power) z'umusaruro wa modulator, iyo modulator igenzurwa kuri Peak point. Igaragaza 3.71dBm ku gishushanyo.
2. Ishusho ya 6 igaragaza imbaraga z'urumuri rw'umusaruro wa modulator, iyo modulator igenzurwa kuri Null point. Igaragaza -46.73dBm muri igishushanyo. Mu igerageza nyaryo, agaciro karatandukanye hafi -47dBm; naho -46.73 ni agaciro gahamye.
3. Kubera iyo mpamvu, igipimo cy’ibura ry’ingufu za DC gipimwa ni 50.4dB.

Ibisabwa kugira ngo habeho igipimo cyo kubura kw'ibinyabuzima byinshi

1. Umuhuza w’imikorere ugomba kugira igipimo cyo kuzimira kinini. Ikiranga umuhuza w’imikorere ni cyo gigena igipimo ntarengwa cyo kuzimira gishobora kugerwaho.
2. Gushyira urumuri rw’ingufu mu buryo bwa polarization bigomba kwitabwaho. Utumashini dukoresha polarization dushobora kwagura ikigereranyo cyo kuzimira hejuru ya 10dB. Mu igerageza rya laboratwari, ubusanzwe hakenewe igikoresho gipima polarization.
3. Abagenzura uburyo bwo gutandukanya ibintu neza. Mu igerageza ryacu rya DC extinction ratio, 50.4dB extinction ratio yagezweho. Mu gihe urupapuro rw'amakuru rw'abakora modulator rugaragaza gusa 40dB. Impamvu y'iri terambere ni uko zimwe muri modulator zigenda vuba cyane. Abagenzura uburyo bwo gutandukanya ibintu bya Rofea R-BC-ANY bavugurura voltage ya bias buri segonda rimwe kugira ngo bihutishe uburyo bwo gusubiza.
