Umugenzuzi wa Polarization ya Fiber ya ROF ya fiber laser
Ibikoresho bya ROF bya fiber optique Ibikoresho byo kugenzura imiterere y'urumuri bya fibre. Iki gicuruzwa ni uburyo bwo kugenzura imiterere y'urumuri bufite uburenganzira bwihariye ku mutungo, bushobora guhindura imiterere y'urumuri ku muvuduko wo hejuru no mu gihe nyacyo. Gifite imiterere yo gutakaza umwanya muto, ingano nto, n'urwego rwo hejuru rwo guhuza, kandi gikoreshwa cyane muri fiber lasers, fibre sensing, high-speed optical communication, na quantum secure communication.
Iki gicuruzwa kigizwe na PZT ifite umurongo wa piezoelectric three axis, ifite circuit yubatswemo ya amplification drive circuit, idasaba input ya voltage nyinshi. Igomba gusa kugenzurwa na porogaramu yoroshye yo kugenzura no kubona amakuru kugira ngo ihindure dynamically dynamically state ya polarization muri state iyo ari yo yose ya polarization mu gihe nyacyo, kandi ikomeze gutuza kuri state iyo ari yo yose ya polarization. Imiterere yayo yihariye ya fibre ituma itakaza <0.5dB na return backback >50dB.

Ugereranyije n’ibindi bicuruzwa bisa, APD ifite ibipimo bya tekiniki bigezweho, kwizerwa no guhuza, kandi ishobora gukoreshwa mu gupima urumuri ruto rudahindagurika nka liDAR no gupima ubuzima bwose bwa fluorescence. Porogaramu zitanga ibisubizo bihendutse.
Iki gicuruzwa gikoresha APD yo gusubiza nabi kugira ngo kigere ku kuzimya vuba inkombe z'amazi n'urusaku ruto rw'ikoranabuhanga, ubushobozi bwo kumenya neza no kubara umwijima muke binyuze mu kunoza imiterere y'ibikoresho by'ikoranabuhanga n'ubushyuhe. Muri byo, ubushobozi bwo kumenya neza bwa 1550nm fotoni imwe ni > 35%; Muri iki gihe, igihe cyo gutitira gishobora kuba hasi ya 80ps; ubushobozi bwo kumenya neza. Kuri 15%, umubare muto w'umwijima ni 500 CPS, naho umuvuduko muto w'inyuma ni 1% @ igihe cyapfuye 5 um; igipimo cyo kubara amazi kugeza kuri 4MCps @ igihe cyapfuye 250ns. Byongeye kandi, ku bintu byihariye byo gukoresha, support bias, screening threshold, igihe cyapfuye n'ibindi bipimo by'imikorere y'umukoresha kugira ngo hongerwe ubushobozi bwo kumenya, igipimo cyo kubara amazi n'ibindi bimenyetso byihariye; support time digital conversion (TDC) function irashobora kumenyekana. Kugira ngo ubone amakuru yo kubara igihe, support free running cyangwa external trigger gating. Hari uburyo bubiri bwo gukora. -
