Naphezu kokusetshenziswa kabanzi kwemigqa yokuxhumana ye-optical nama-transceivers nama-lasers, ukucubungula idatha ye-all-optical kusalokhu kuyimfihlo eqashwe ngokucophelela. Ucwaningo olusha lwethimba lososayensi abavela eRussia naseGreat Britain luzosiza ukuqhubekisela phambili le ndlela. enye yezimfihlakalo eziyisisekelo zokusebenzelana okuqinile phakathi kwama-molecule okukhanya nama-organic.
I-Organics inososayensi abanentshisekelo ngesizathu. Ukuvela kwezinto eziphilayo zasemhlabeni kuxhunyaniswe ngokungenakuhlukaniswa nokusebenzelana nokukhanya. Futhi ixhumeke kakhulu! Ulwazi lwemithetho eyisisekelo yalokhu kuxhumana luzosiza ekwenzeni inqubekelaphambili enkulu ekuthuthukisweni kwezinto zikagesi ezisekelwe ezintweni eziphilayo. Ama-LED, ama-laser kanye nezikrini ze-OLED ezithandwa kakhulu ziyizimboni ezimbalwa ezingasheshisa ukukhula kwazo ngolwazi olusha.
Impumelelo ekuqondeni izenzakalo zokusebenzelana okuqinile kokukhanya nama-molecule ezinto eziphilayo yenziwa ithimba lososayensi abavela e-Skoltech Hybrid Photonics Laboratory kanye naseNyuvesi yaseSheffield (UK). Izimiso zokuhlanganisa okuqinile zinikeza amathuba ayingqayizivele okusebenza kolwazi lwe-optical yonke ngaphandle kokulahlekelwa okuphawulekayo kwesivinini sesignali namandla lapho kuguqulwa kube okwamanje, okwenzeka namuhla. Lolu cwaningo luyisihloko se-athikili ku-Nature Communications Physics (umbhalo ngesiNgisi utholakala mahhala kokuthi ).
Njengezifundo zangaphambilini zokusebenzelana okuqinile kokukhanya (ama-photons) nendaba, ososayensi bafunda "ukuxuba" kwama-photons ne-electronic excitation yama-molecule, noma ama-exciton. Ukusebenzisana kwama-photon nama-quasiparticlesβama-excitonβkuholela ekubonakaleni kwamanye ama-quasiparticlesβama-polaritons. Ama-polariton ahlanganisa isivinini esikhulu sokusakazeka kokukhanya kanye nezakhiwo ze-elekthronikhi zendaba. Kalula nje, i-photon, njengokungathi, yenziwe imizimba futhi ithola izakhiwo eziseduze nalezo ze-electron. Ngalokhu kakade !
Ngokusekelwe ku-polariton, kungenzeka ukudala i-transistor esebenzayo futhi, ngokuzayo, iprosesa. Ikhompiyutha enjalo ngeke idinge izinzwa zokukhipha kanye ne-photoconverting, ezinokusebenza okuphansi nokusebenza okuphansi, futhi ithimba elivela e-Skoltech namuhla liye laqeda imfihlakalo yokusebenzisana kwe-polariton.
"Kuyaziwa kusukela ekuhloleni ukuthi lapho ama-polaritons ehlangene ezintweni eziphilayo, ukuguquguquka okubukhali kwezakhiwo ze-spectral kwenzeka, futhi lokhu kushintshwa kuhlale kuholela ekwandeni kwemvamisa yama-polariton. Lokhu kuyinkomba yezinqubo ezingaqondile ezenzeka ohlelweni, njengesibonelo, ukushintsha kombala wensimbi njengoba ishisa. "
Iqembu lihlaziye idatha yokuhlola futhi lasungula ukuncika okuyinhloko kokushintshwa kwemvamisa ye-polariton kumapharamitha abaluleke kakhulu okusebenzelana kokukhanya nama-molecule ezinto eziphilayo. Ngokokuqala ngqa, kutholwe ithonya elinamandla lokudluliswa kwamandla phakathi kwama-molecule angomakhelwane ezindaweni ezingaqondile zama-polaritons. Lokhu kwembula amandla okushayela ama-polaritons. Ukwazi uhlobo lomshini, kungenzeka ukuthuthukisa ithiyori futhi uyiqinisekise ngokuhlolwa okusebenzayo, isibonelo, ukuxhuma ama-polariton condensates amaningana abe yisifunda esisodwa ukuze kwakhiwe ama-polariton processors.
