Gucukumbura amabanga yumucyo: Porogaramu nshya kuriUmuyoboro wa Electro-Optic LiNbO3 modulator

LiNbO3 modulatorIcyiciro cya modulator nikintu cyingenzi gishobora kugenzura ihinduka ryicyiciro cyumucyo, kandi kigira uruhare runini mugutumanaho kwa optique no kwiyumvisha ibintu. Vuba aha, ubwoko bushya bwaicyiciroyakwegereye abashakashatsi naba injeniyeri, ikora ku burebure butatu bwa 780nm, 850nm na 1064nm, hamwe numuyoboro mugari wa 300MHz, 10GHz, 20GHz na 40GHz.

Ikintu cyingenzi kiranga iki cyiciro modulator ni modulisiyo yo hejuru hamwe no gutakaza igihombo gito. Gutakaza kwinjiza bivuga kugabanuka kwingufu cyangwa ingufu za signal optique nyuma yo kunyura muri modulator. Igihombo cyo kwinjiza iki cyiciro modulator ni gito cyane, byemeza ubusugire bwikimenyetso, kugirango ikimenyetso gishobora gukomeza imbaraga nyinshi nyuma yo guhinduka.

Mubyongeyeho, moderi ya moderi ifite ibiranga igice cya kabiri cya voltage. Igice cya kabiri cyumuvuduko ni voltage ikeneye gukoreshwa kuri modulator kugirango uhindure icyiciro cyumucyo kuri dogere 180. Umuvuduko muke wa kimwe cya kabiri cyumuvuduko bivuze ko hakenewe ingufu nkeya gusa kugirango habeho impinduka zikomeye mugice cya optique, bigabanya cyane ingufu zikoreshwa mubikoresho.

Kubireba imirima ikoreshwa, iyi moderi nshya modulator irashobora gukoreshwa cyane muburyo bwa optique ya fibre optique, itumanaho rya fibre optique, gutinda kwicyiciro (kwimura), no gutumanaho kwa kwant. Muri optique ya fibre optique, moderi moderi irashobora kunoza ibyiyumvo no gukemura bya sensor. Mu itumanaho rya fibre optique, irashobora kuzamura umuvuduko witumanaho no gutanga amakuru neza. Mugutinda kwicyiciro (kwimura), irashobora kugenzura neza icyerekezo cyo gukwirakwiza urumuri; Mu itumanaho rya kwant, irashobora gukoreshwa mugucunga no gukoresha kwant leta.

Muri rusange, icyiciro gishya modulator iduha uburyo bunoze kandi bunoze bwo kugenzura optique, bizazana impinduka zimpinduramatwara mubice byinshi. Turateganya ko tekinoroji izarushaho gutera imbere no gutunganywa mugihe kizaza, ikaduhishurira amabanga meza kuri twe.
