Niki aicyiciro

Icyiciro cya modulator nicyitegererezo cyiza gishobora kugenzura icyiciro cya laser. Ubwoko busanzwe bwa modulator ni Pockels agasanduku-gashingiyeamashanyarazi ya electro-optiquen'amazi ya kirisiti ya moderi, irashobora kandi kwifashisha ibipimo byerekana ubushyuhe bwa fibre yumuriro cyangwa impinduka ndende, cyangwa kurambura kugirango uhindure uburebure. Modulator zitandukanye zikoreshwa murwego rwo guhuza optique, aho urumuri rwahinduwe rukwirakwiza mumurongo.

Ibintu byingenzi biranga icyiciro cya modulator zirimo: Ingano yicyiciro cya modulasiyo (igena indangagaciro ya modulasiyo hamwe nimbaraga zijyanye na bande ya bande) isaba disiki ya voltage modulation ya bande (modulation frequency range), theamashanyarazi ya optiqueni muburyo bwa GHz, kandi igikoresho ukoresheje ingufu zumuriro cyangwa ibintu bya kirisiti ya kirisiti ni munsi cyane yumurongo mugari wibikoresho bya aperture. Kugabanya urumuri rwa radiyo yumurongo wahinduwe Ibipimo byo hanze byigikoresho Iyi miterere iratandukanye cyane kubwoko butandukanye bwa modulator. Kubwibyo, modulator zitandukanye zigomba gukoreshwa mubikorwa bitandukanye.

Ingero zicyiciro cya modulator ikoreshwa zirimo: Moderi yicyiciro muri laser resonator ya lazeri imwe yumurongo wa lazeri irashobora gukoreshwa muguhuza umurongo wumurongo wumurongo, cyangwa gukora uburyo bwo gufunga (FM moderi-gufunga) ya lazeri kugirango igabanye urumuri niba rufite ubukana buringaniye, rushobora gukoreshwa muburyo bwa stabilisation ya lazeri ikoresheje ibyuma byerekana ibipimo bya interineti, bisaba uburyo bwo gupima ibyiciro bya interineti. Ibipimo bimwe bisaba ibimamara byinshyi, biboneka kubwibyabaye umurongo umwe wumurongo wa moderi ya moderi. Muri iki kibazo, icyiciro cya modulasiyo gikeneye kuba gikomeye, kugirango ubashe kubona imirongo myinshi kuruhande. Muri data yohereza amakuru ya optique ya fibre itumanaho, icyiciro cya moderi kirashobora gukoreshwa mugutandukanya amakuru yatanzwe. Kurugero, icyiciro-shift urufunguzo rukoreshwa.
