Ihinduka rya bipolar icyiciro

Bipolar yorohejeicyiciro

Mu kibuga cyitumanaho ryihuse ryitumanaho hamwe na tekinoroji ya kwant, modulator gakondo zihura nibikorwa bikomeye! Ibimenyetso bidahagije byera, kugenzura ibyiciro bidasubirwaho, hamwe no gukoresha amashanyarazi menshi cyane - izi mbogamizi zibangamira iterambere ryikoranabuhanga.

Bipolaramashanyarazi ya optiqueIrashobora kugera ku byiciro bibiri bikomeza guhinduranya icyiciro cyibimenyetso bya optique. Biranga kwishyira hamwe kwinshi, gutakaza kwinjiza kwinshi, kwaguka kwinshi kwagutse, umuvuduko muke wa voltage, hamwe nimbaraga zangiza cyane. Zikoreshwa cyane muburyo bwo kugenzura chirp optique muri sisitemu yo gutumanaho yihuta ya optique hamwe nibisekuruza bya leta muri sisitemu yo gukwirakwiza kwant. Igisekuru cyuruhande muri sisitemu ya ROF no kugabanya gukwirakwiza Brillouin ikwirakwizwa (SBS) muri sisitemu yo gutumanaho ya fibre optique, mubindi bice.

Uwitekabipolar icyiciroKugera kugenzura neza icyiciro cyibimenyetso bya optique binyuze mubyiciro bibiri bikomeza icyiciro cya modulisiyo, kandi cyane cyane byerekana agaciro kadasanzwe muburyo bwihuse bwitumanaho rya optique hamwe no gukwirakwiza kwant kwinshi.

. Irashobora guhuzwa neza nimbaraga zitanga ingufu za laser kandi irakwiriye kubyara umusaruro mwiza wa milimetero-umurongo wa bande muri sisitemu ya ROF (Optical Wireless).

2. Guhagarika Chirp hamwe nubuyobozi bwa SBS: Mugihe cyihuta cyihuta cohereza, umurongo waicyiciroirashobora guhagarika neza amajwi yibimenyetso bya optique. Mu itumanaho rya optique ya fibre itumanaho, mugutezimbere ubujyakuzimu bwa modulasiyo, ingaruka za Brillouin zikwirakwiza (SBS) zirashobora kugabanuka cyane, bityo bikagura intera yoherejwe.

Mugukwirakwiza urufunguzo rwa kwant (QKD), imiterere ya foton ebyiri ikora nka "kwantum urufunguzo" kugirango itumanaho ryizewe - ubunyangamugayo bwateguwe bugena mu buryo butaziguye imitungo idateze amatwi urufunguzo. "Flexibilité" ya moderi ya bipolar modulaire igaragarira mubushobozi bwayo bwo guhindura imikorere yibice byicyiciro kugirango ihuze n’imihindagurikire y’ibidukikije ihuza fibre optique itandukanye (nk’imihindagurikire y’ubushyuhe na feri igenda iterwa no guhangayikishwa n’imashini), bigatuma imikorere y’ibisekuru ikora neza ya fotoni ebyiri. "Igihagararo" kigerwaho hifashishijwe kugenzura neza ubushyuhe hamwe na tekinoroji yo gufunga ibyuma, ibyo bikaba byerekana urusaku rwicyiciro kiri munsi y’urusaku rw’urusaku kandi bikarinda kwangirika kwa kwant mu gihe cyo kwanduza. Iyi mikorere ibiri ya "flexible + stabilite" ntabwo yongerera gusa igipimo cyo gukwirakwiza intera ngufi mu miyoboro y’akarere ka metropolitani (nkikigereranyo cyo kwibeshya gato kiri munsi ya 1% muri kilometero 50), ariko kandi gishyigikira ubunyangamugayo bwimfunguzo mugukwirakwiza intera ndende mumiyoboro ihuza abantu (nka kilometero zirenga ijana mumijyi), bihinduka igice cyibanze cyo kubaka umuyoboro wogutumanaho "umutekano rwose".
