Modulator y'amashanyarazini igikoresho cy'ingenzi cyo guhindura ikimenyetso cya laser gihoraho hakoreshejwe amakuru, umurongo wa radiyo n'ibimenyetso by'isaha. Imiterere itandukanye ya modulator ifite imirimo itandukanye. Binyuze muri modulator y'urumuri, ubukana bw'imiraba y'urumuri bushobora guhinduka gusa, ahubwo nanone imiterere y'urumuri rw'imiraba y'urumuri ishobora guhinduka. Modulator zikoreshwa cyane ni Mach-Zehndermodulator z'ubukananamodulator z'ibyiciro.
ItsindaModulator y'ubukana bwa LiNbO3ikoreshwa cyane muri sisitemu y'itumanaho ryihuse cyane, uburyo bwo kubona urumuri muri laser na sisitemu ya ROF kubera imikorere yayo ya electro-optic. Uruhererekane rwa R-AM rushingiye ku miterere ya MZ push-pull n'igishushanyo cya X-cut, rufite imiterere ihamye n'iya shimi, ishobora gukoreshwa haba mu igerageza rya laboratwari no mu nganda.

Uburebure bw'umuraba：850nm/1064nm/1310nm/1550nmn
Ubugari bw'umuyoboro w'itumanaho: 10GHz/20GHz/40GHz
Ibindi: Uburyo bwo gupima imbaraga za ER/CascadingModulator ya MZ/Modulator ya MZ ijyanye n'ibice bibiri
Ikiranga:
Igihombo gito cyo gushyiramo
Igice cya volteji kiri hasi
Ubwirinzi bwinshi
Porogaramu:
Sisitemu za ROF
Gukwirakwiza urufunguzo rwa Quantum
Sisitemu zo gutahura hakoreshejwe laser
Guhindura imiyoboro yo ku ruhande
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.
ROF imaze imyaka icumi yibanda ku miyoboro n'ibice byayo bya elegitoroniki. Dukora modulators zikora neza cyane kandi dutanga ibisubizo na serivisi bishya ku bashakashatsi ba siyansi n'abahanga mu nganda. Modulators za Rofea zifite voltage nkeya yo gutwara no gutakaza ingufu nke zakoreshejwe cyane cyane mu gukwirakwiza urufunguzo rwa quantum, sisitemu za radio-over-fiber, sisitemu zo kubona laser, na telecommunication y'ikoranabuhanga igezweho.
Dutanga kandi modulators nyinshi zihariye zo guhindura imiterere y'amajwi, nka modulators za 1 * 4 array phase, Vpi ya ultra-low, na modulators za ultra-high extinction ratio modulators, zikoreshwa cyane cyane muri za kaminuza n'ibigo. Byongeye kandi, dukora amplifier ya RF (umushoferi wa modulators) na BIAS controller, photonics detector nibindi.
Mu gihe kiri imbere, tuzakomeza kunoza uruhererekane rw'ibicuruzwa bisanzweho, kugira ngo twubake itsinda ry'abahanga mu bya tekiniki, dukomeze guha abakoresha ibicuruzwa byiza, byizewe kandi bigezweho na serivisi za tekiniki.
