Igikoresho cyo kugenzura uburinganire bw'imigozi (fiber polarization controller) ni iki?
Ibisobanuro: Igikoresho gishobora kugenzura imiterere y'urumuri rwa polarization mu migozi y'urumuri. Byinshi muri byoibikoresho bya fibre optique, nka interferometers, bisaba ubushobozi bwo kugenzura imiterere y'urumuri muri fibre. Kubwibyo, hakozwe ubwoko butandukanye bw'ibikoresho bigenzura imiterere ya fibre.
Umugenzuzi w'amatwi y'udusimba two mu bwoko bwa "bend optical fibre"
Ikintu gisanzweurwego rugenzura imiterere y'ikirereBigerwaho binyuze mu kunama (cyangwa kuzunguruka) imigozi y'urumuri kugira ngo haboneke birefringence. Gutinda kose (ingano ya birefringence) bingana n'uburebure bwa fibre kandi bingana n'umuyoboro w'urumuri. Bifitanye isano kandi n'ubwoko bwa fibre y'urumuri. Mu bihe bimwe na bimwe, fibre y'urumuri ishobora gupfundikirwa inshuro nyinshi hakoreshejwe umuyoboro wihariye w'urumuri kugira ngo haboneke gutinda kwa λ/2 cyangwa λ/4.

Ishusho ya 1: Igenzura ryo gutandukanya amatwi y'udusimba, rigizwe n'imirongo itatu ya fiber optique ishobora kuzenguruka ku murongo w'umugozi w'umugozi.
Ubusanzwe, imiyoboro itatu ikoreshwa mu gukora inkingi, aho umuyoboro wo hagati ari igice cy'umuraba n'impande ebyiri ari igice cy'umuraba. Buri muyoboro ushobora kuzenguruka ku murongo w'imiyoboro y'amashanyarazi n'isohoka. Mu guhindura icyerekezo cy'imiyoboro itatu, imiterere y'umuraba wihariye w'uburebure ishobora guhindurwamo imiterere iyo ari yo yose y'umuraba winjira. Ariko, ingaruka kuri muyoboro zifitanye isano n'uburebure bw'umuraba. Iyo imbaraga nyinshi (zikunze kubaho mu miyoboro migufi cyane), habaho kuzunguruka kwa muraba winjira. Umurambararo wa muraba winjira winjira winjira ntushobora kuba muto cyane, bitabaye ibyo kuzunguruka bizatera ibindi bihombo byo kuzunguruka. Ubundi bwoko buto, kandi butarangwa no kuzunguruka, bukoresha uburyo bukomeye bwo kuzunguruka (kubungabunga muraba winjira) bw'imiyoboro y'amashanyarazi aho gukoresha imiyoboro y'amashanyarazi.
ByakasweUmugenzuzi wa Fibre Polarization
Hari igikoresho gishobora kubona amapine ahindagurika, gishobora gukanda uburebure bw'imigozi y'urumuri ku rugero runaka munsi y'umuvuduko utandukanye. Mu kuzenguruka buhoro buhoro no gukanda imigozi y'urumuri ku ruhande rwayo, no kuyihambira ku ntera runaka uvuye ku gice cyo gukanda, imiterere iyo ari yo yose ya polarization irashobora kuboneka. Mu by'ukuri, imikorere imwe na Babinet Soleil compensator (ubwoko bw'umuvudukoigikoresho cy'urumuriikubiyemo imigozi ibiri ya birefringent wedges) ishobora kuboneka, nubwo amahame y'imikorere yayo atandukanye. Ahantu henshi ho gukanda hashobora gukoreshwa, aho igitutu gusa, atari inguni yo kuzenguruka, gihinduka. Impinduka z'igitutu zikunze kugerwaho hakoreshejwe transducers za piezoelectric. Iki gikoresho gishobora kandi gukora nka polarizer, aho piezoelectric itwarwa n'imirongo itandukanye cyangwa ibimenyetso bidasanzwe.
