Imodyuli yenqanaba le-bipolar eguquguqukayo

I-bipolar eguquguqukayoimodyuli yesigaba

Kwibala lonxibelelwano olukwisantya esiphezulu kunye netekhnoloji ye-quantum, iimodyuli zemveli zijongene nemiqobo yokusebenza kakhulu! Ukungacoceki komqondiso okwaneleyo, ukulawulwa kwesigaba esingenakuguquguquka, kunye nokusetyenziswa kwamandla okugqithisileyo kwenkqubo - le mingeni ithintela uphuhliso lobuchwepheshe.

I-bipolarimodyuli yesigaba se-electro-opticalinokufezekisa i-modulation eqhubekayo yenqanaba lesigaba sezibonakaliso ze-optical. Babonisa ukudityaniswa okuphezulu, ilahleko ephantsi yokufaka, i-bandwidth ephezulu yokumodareyitha, i-voltage ephantsi yesiqingatha-amaza, kunye nomonakalo omkhulu wamandla okukhanya. Zisetyenziselwa ikakhulu ukulawula i-chirp ye-optical kwi-high-speed optical communication systems kunye nokuveliswa kombuso okubambeneyo kwiinkqubo zokusasaza eziphambili ze-quantum. Ukuveliswa kwee-sidebands kwiinkqubo ze-ROF kunye nokunciphisa i-Brillouin scattering (SBS) ekhuthazwayo kwiinkqubo zonxibelelwano ze-analog optical fiber, phakathi kwezinye iindawo.

Iimodyuli yesigaba se-bipolarifezekisa ulawulo oluchanekileyo lwesigaba sezibonakaliso ze-optical ngokusebenzisa i-modulation yesigaba esiqhubekayo, kwaye ngokukodwa ibonisa ixabiso elikhethekileyo kwi-high-speed optical communication kunye ne-quantum key distribution.

1. Ukuhlanganiswa okuphezulu kunye nomda womonakalo omkhulu: Ithatha idizayini edibeneyo ye-monolithic, i-compact ngobukhulu, kwaye isekela umonakalo omkhulu wamandla optical. Iyakwazi ukuhambelana ngokuthe ngqo kunye nemithombo ye-laser ephezulu kwaye ifanelekile kwisizukulwana esisebenzayo se-millimeter-wave sidebands kwiinkqubo ze-ROF (Optical Wireless).

2. Uxinzelelo lwe-Chirp kunye nolawulo lwe-SBS: Kwisantya esiphezulu sothumelo oluhambelanayo, umgca weukumodareyitha kwesigabainokucinezela ngokufanelekileyo ukuntyiloza kweempawu zamehlo. Kunxibelelwano lwe-analog optical fiber, ngokulungisa ubunzulu bemodulation yesigaba, impembelelo yeBrillouin scattering (SBS) evuselelweyo ingancitshiswa kakhulu, ngaloo ndlela yandisa umgama wothumelo.

Kwi-quantum key distribution (QKD), imeko edibeneyo ye-photon pairs isebenza "njengesitshixo se-quantum" yonxibelelwano olukhuselekileyo - ukuchaneka kokulungiswa kwayo kubeka ngokuthe ngqo ipropati engabonakaliyo yesitshixo. "Ukuguquguquka" kwe-modulator yesigaba se-bipolar kubonakaliswe kwikhono layo lokulungelelanisa ngokuguquguqukayo iiparitha zesigaba ukuze zihambelane nokuphazamiseka kokusingqongileyo kweendlela ezahlukeneyo ze-fiber optical links (ezifana nokutshintsha kweqondo lokushisa kunye nokunyuka kwesigaba okubangelwa ukuxinzezeleka komatshini), ukuqinisekisa ukusebenza kakuhle kwesizukulwana esiphezulu se-photon pairs. "Uzinzo" lufezekiswa ngolawulo oluchanekileyo lobushushu kunye ne-phase-locking frequency technology, ethintela ingxolo yesigaba esingaphantsi komda wengxolo ye-quantum kwaye ithintele ukungahambi kakuhle kweemeko ze-quantum ngexesha lokudluliselwa. Olu phawu luntlu-mbini “lokuguquguquka + uzinzo” aluphuculi nje kuphela umlinganiselo wokusasazwa komgama omfutshane womgama kuthungelwano lwengingqi yemetropolitan (njengesantya esincinci sempazamo esingaphantsi kwe-1% phakathi kweekhilomitha ezingama-50), kodwa ikwaxhasa imfezeko yezitshixo kuthumelo lomgama omde kuthungelwano oludityanisiweyo (ezifana ngaphaya kwekhulu leekhilomitha eziphantsi kolwakhiwo lwezixeko), ikhuselekile” inethiwekhi yonxibelelwano lwequantum.
