Ososayensi nonjiniyela bathuthukise ubuchwepheshe obusha obuthembisa ukuguqula izinhlelo zokuxhumana zasemkhathini. Besebenzisa ama-modulators asezingeni eliphezulu angu-850nm electro-optic asekela i-10G, ukulahlekelwa okuphansi kokufakwa, i-voltage ephansi, kanye nokuzinza okuphezulu, ithimba lithuthukise ngempumelelo uhlelo lokuxhumana lwe-optical lwesikhala kanye nesistimu yemvamisa yomsakazo ebizayo engadlulisa idatha ngesivinini esikhulu kakhulu ngaphandle kobukhulu obukhulu. Ngalobu buchwepheshe obuthuthukisiwe, ama-space probe nama-satellite angadlulisa idatha eningi ngesivinini esisheshayo, okwenza kube nokuxhumana ngesikhathi sangempela noMhlaba kanye nokwabelana ngedatha okusebenzayo phakathi kwe-spacecraft. Lokhu kuyintuthuko ebalulekile yokuhlola isikhala, njengoba ukuxhumana ne-spacecraft bekulokhu kuyisithiyo esikhulu ocwaningweni lwesayensi. Uhlelo lwakhiwe phezu kwesisekelo sesikhathi se-cesium atomic esizinzile kakhulu, okuqinisekisa isikhathi esinembile sokudluliselwa kwedatha ngakunye. Ngaphezu kwalokho, kufakwe i-pulse generator ukuqinisekisa ukuguqulwa okunembile kwesignali ye-optical. Ithimba liphinde lafaka izimiso ze-quantum optics ukuze lithuthukise amakhono esistimu. Ngokusebenzisa izakhiwo ze-quantum zokukhanya, bakwazile ukukhiqiza uhlelo lokuxhumana oluphephile kakhulu olumelana nokulalela nokugenca. Ukusetshenziswa okungenzeka kwalolu buchwepheshe kukhulu futhi kusakazeke kabanzi. Kusukela ekuxhumaneni kwesathelayithi okusheshayo nokuthembekile kuya ekuqondeni nasekuqondeni indawo yonke yethu, lobu buchwepheshe bunamandla okuguqula ukuhlola isikhala njengoba sibazi. Ithimba manje lisebenza ukuze lithuthukise ubuchwepheshe futhi lihlole izinhlelo zokusebenza zezentengiselwano ezingaba khona. Ngamakhono alo okudlulisa idatha ngesivinini esikhulu kanye nezici zokuphepha ezithuthukisiwe, lolu hlelo olusha lokuxhumana isikhala luzodingeka kakhulu eminyakeni ezayo.
I-modulator ye-electro optic intensity engu-850 nm 10G
Incazelo emfushane:
I-ROF-AM 850nm lithium niobate optical intensity modulator isebenzisa inqubo yokushintshana kwe-proton ethuthukisiwe, enokulahlekelwa okuphansi kokufakwa, i-bandwidth ephezulu yokuguquguquka, i-voltage ephansi ye-half-wave, nezinye izici, ikakhulukazi ezisetshenziselwa uhlelo lokuxhumana lwe-space optical, isisekelo sesikhathi se-cesium atomic, amadivayisi akhiqiza i-pulse, i-quantum optics, nezinye izinkambu.
Isebenzisa inqubo yokushintshana kweprotoni ethuthukisiwe, enokulahlekelwa okuphansi kokufakwa, i-bandwidth ephezulu yokuguquguquka, i-voltage ephansi ye-half-wave, nezinye izici, esetshenziselwa kakhulu uhlelo lokuxhumana lwe-space optical, isisekelo sesikhathi se-cesium atomic, amadivayisi akhiqiza i-pulse, i-quantum optics, nezinye izinkambu.
