Ho ferekana kelellongmodulator ea mohato
Lebaleng la puisano e phahameng ea optical le theknoloji ea quantum, li-modulator tsa setso li tobane le mathata a matla a ts'ebetso! Bohloeki bo sa lekaneng ba matšoao, taolo ea mekhahlelo e sa fetoheng, le tšebeliso e feteletseng ea matla a sistimi - liphephetso tsena li sitisa nts'etsopele ea theknoloji.
Bipolarelectro-optical phase modulatore ka finyella mekhahlelo e 'meli e tsoelang pele ea modulation ea mohato oa lipontšo tsa optical. Li na le kopanyo e phahameng, tahlehelo e tlase ea ho kenya, bandwidth e phahameng ea modulation, voltage e tlase ea halofo ea maqhubu, le matla a matla a optical a senyang haholo. Li sebelisoa haholo-holo bakeng sa taolo ea optical chirp lits'ebetsong tsa puisano tsa optical tse lebelo le holimo le tlhahiso e kentsoeng ea mmuso litsamaisong tsa kabo ea bohlokoa ea quantum. Ho hlahisa li-sidebands ho litsamaiso tsa ROF le phokotso ea ho hasanya ha Brillouin (SBS) ho li-analog optical fiber communication systems, har'a likarolo tse ling.
Thebipolar phase modulatore finyella taolo e nepahetseng ea mohato oa lipontšo tsa optical ka ho feto-fetoha ha mekhahlelo e 'meli e tsoelang pele,' me ka ho khetheha e bontša bohlokoa bo ikhethang ba puisano ea optical e potlakileng le kabo ea bohlokoa ea quantum.
1. Ho kopanya ho phahameng le moeli o phahameng oa tšenyo: E amohela moralo o kopantsoeng oa monolithic, o kopane ka boholo, 'me o tšehetsa matla a maholo a ho senya matla a optical. E ka tsamaellana ka kotloloho le mehloli ea laser ea matla a phahameng 'me e loketse tlhahiso e sebetsang ea li-sidebands tsa millimeter-wave ho litsamaiso tsa ROF (Optical Wireless).
2. Khatello ea li-Chirp le tsamaiso ea SBS: Phetisong e kopanetsoeng ka lebelo le phahameng, moeli oaho feto-fetoha ha maemoe ka thibela ka katleho ho lla ha matšoao a optical. Puisanong ea analog optical fiber, ka ho ntlafatsa botebo ba modulation ea mohato, phello e khothaletsoang ea Brillouin scattering (SBS) e ka fokotsoa haholo, ka hona, ea atolosa sebaka sa phetisetso.
In quantum key distribution (QKD), boemo bo kentsoeng ba photon pairs bo sebetsa e le "quantum key" bakeng sa puisano e sireletsehileng - ho nepahala ha ho lokisoa ha eona ho khetholla ka ho toba thepa e sa utloisiseheng ea senotlolo. "Ho feto-fetoha ha maemo" ea modulator ea bipolar phase modulator e bonahala ka bokhoni ba eona ba ho fetola mekhahlelo ea mekhahlelo ho ikamahanya le litšitiso tsa tikoloho ea li-link tse fapaneng tsa optical fiber (joalo ka ho fetoha ha mocheso le ho phalla ha karolo ho bakoang ke khatello ea mochine), ho netefatsa katleho e phahameng ea moloko oa lipara tsa photon tse kentsoeng. "Botsitso" bo finyelloa ka ho laola mocheso o nepahetseng le theknoloji ea maqhubu a ho koala phasewete, e thibelang lerata la mohato ka tlase ho moeli oa lerata la quantum le ho thibela ho se lumellane ha linaha tsa quantum nakong ea phetisetso. Karolo ena e habeli ea "flexibility + stability" ha e ntlafatse feela sekhahla sa phetisetso ea sebaka se sekhuts'oane ho marang-rang a libaka tsa litoropo (joalo ka sekhahla sa phoso se ka tlase ho 1% ka har'a lik'hilomithara tse 50), empa hape se ts'ehetsa ts'ebetso ea linotlolo tsa phetisetso ea sebaka se selelele ho marang-rang a marang-rang (joalo ka lik'hilomithara tse fetang lekholo ho theosa le teropo e tlase). safe” quantum communication network.
