02amashanyarazi ya optiquenaamashanyarazi ya optiqueibimamara bya optique
Ingaruka ya electro-optique yerekana ingaruka ko indangagaciro yo kugabanya ibintu ihinduka mugihe umurima wamashanyarazi ushyizwe. Hariho ubwoko bubiri bwingenzi bwingaruka za electro-optique, imwe ningaruka yibanze ya electro-optique, izwi kandi nka Pokels ingaruka, bivuga ihinduka ryumurongo wibipimo byerekana ibintu byangiritse hamwe numurima wamashanyarazi washyizweho. Ibindi ningaruka ya kabiri ya electro-optique, izwi kandi nka Kerr ingaruka, aho ihinduka ryibipimo byangirika byibikoresho bigereranywa na kare yumurima wamashanyarazi. Modulator nyinshi za electro-optique zishingiye ku ngaruka za Pokels. Dukoresheje moderi ya electro-optique, turashobora guhindura icyiciro cyumucyo wabaye, kandi dushingiye kumyanya ihindagurika, binyuze mubihinduka runaka, dushobora kandi guhindura ubukana cyangwa polarisiyasi yumucyo.
Hariho ibintu byinshi bitandukanye bya kera, nkuko bigaragara ku gishushanyo cya 2. Umuyoboro mugari. Niba optique ya optique hamwe nibisubirwamo byinshi bisabwa, modulator ebyiri cyangwa nyinshi zirakenewe muri caskade, nkuko bigaragara ku gishushanyo cya 2 (d) (e). Ubwoko bwa nyuma bwimiterere ibyara optique yumuriro bita electro-optique resonator, aribwo moderi ya electro-optique yashyizwe muri resonator, cyangwa resonator ubwayo irashobora gutanga ingufu za electro-optique, nkuko bigaragara ku gishushanyo cya 3.

03 Electro-optique modulation optique yumurongo wibiranga
Inyungu imwe: guhuza
Kubera ko urumuri rwumucyo ari lazeri yagutse ya laser, kandi moderi ya electro-optique nayo ifite umurongo mugari wa enterineti, umurongo wa electro-optique modulation optique yumurongo nawo uhuza umurongo. Usibye inshuro zishobora gukurikiranwa, kuva ibisekuru bya moderi ya modulator irahinduka, inshuro zisubiramo za optique ya optique yumurongo nayo irashobora guhinduka. Iyi ni akarusho optique yumurongo wa optique ikorwa na moderi ifunze laseri na micro-resonator idafite.
Inyungu ebyiri: inshuro zisubiramo
Igipimo cyo gusubiramo ntabwo cyoroshye gusa, ariko kandi gishobora kugerwaho udahinduye ibikoresho byubushakashatsi. Ubugari bwumurongo wa electro-optique modulasique optique yumurongo wa tombora ihwanye nuburinganire bwumubyigano, ubwinshi bwubucuruzi bwa electro-optique modulator yumurongo wa 40GHz, hamwe na electro-optique modulasique optique yumurongo wogusubiramo inshuro zishobora kurenza umurongo wa optique yumurongo wogukora nubundi buryo bwose usibye micro resonator (ishobora kugera kuri 100GHz).
Inyungu ya 3: gushiraho ibintu
Ugereranije n'ikimamara cya optique cyakozwe nubundi buryo, imiterere ya disiki ya optique ya optique ya optique ya optique igenwa na dogere nyinshi zubwisanzure, nkibimenyetso bya radiyo yumurongo wa radiyo, voltage bias, polarisiyasi yibyabaye, nibindi, bishobora kuba ikoreshwa mugucunga ubukana bwibimamara bitandukanye kugirango ugere ku ntego yo gushushanya ibintu.
04 Ikoreshwa rya electro-optique modulator optique yumurongo wikimamara
Mubikorwa bifatika bya electro-optic modulator optique yumurongo wa tombora, irashobora kugabanwa mubice bibiri kandi bibiri. Umurongo utandukanijwe numurongo umwe wikimamara ni gito cyane, kuburyo burashobora kugerwaho. Muri icyo gihe, ugereranije na optique yumurongo wa optique ikorwa na laser-moderi ifunze, igikoresho cya electro-optique modulator optique ya frequency frequency ni nto kandi nziza. Kabiri ikomatanya ya sprometrike ikorwa no guhuza ibice bibiri bihujwe hamwe hamwe nibisubirwamo bitandukanijwe gato, kandi itandukaniro ryinshuro zisubiramo ni umurongo utandukanya umurongo mushya wo guhuza ibice. Ikoreshwa rya optique yumurongo wa tekinoroji irashobora gukoreshwa mugushushanya kwa optique, kuringaniza, gupima uburebure, kugereranya ibikoresho, gushiraho imiterere ya flake ya sprifike, radiyo yumurongo wa fotonike, itumanaho rya kure, kwiba kwa optique nibindi.
