Izinhlelo zokusebenza ezisezingeni eliphezulu kuma-optics eziholwa ama-modulators optical
Isimiso se-ukuguqulwa kokukhanyaakuyona inkimbinkimbi. Ngokuyinhloko ifinyelela ekuguqulweni kwe-amplitude, isigaba, i-polarization, i-refractive index, izinga lokumuncwa kanye nezinye izici zokukhanya ngokusebenzisa izinto zangaphandle, ukulawula ngokunembile isignali yokukhanya, njengokuvumela ama-photon ukuthi athwale futhi adlulisele ulwazi. Izingxenye eziyisisekelo ze-commoni-electro-optic modulatorzifaka izingxenye ezintathu: amakristalu e-electro-optic, ama-electrode, kanye nezinto ezibonakalayo. Ngesikhathi senqubo yokuguqulwa kokukhanya, izinto eziku-optical modulator zishintsha inkomba yazo yokukhanya, izinga lokumuncwa kanye nezinye izakhiwo ngaphansi kwethonya lezinto zangaphandle (njengezinkundla zikagesi, izinkundla zomsindo, izinguquko zokushisa noma amandla omshini), ngaleyo ndlela zithinta ukuziphatha kwama-photon njengoba edlula ezintweni, njengokulawula izici zokusabalala kokukhanya (ubukhulu, isigaba, ukwahlukana, njll.). I-electro-optical crystal iyingqikithi yei-modulator yokukhanya, inesibopho sokuphendula ezinguqukweni ensimini kagesi kanye nokushintsha inkomba yayo yokukhanya. Ama-electrode asetshenziselwa ukusebenzisa amasimu kagesi, kuyilapho izingxenye ezibonakalayo ezifana nama-polarizers nama-waveplate zisetshenziselwa ukuqondisa nokuhlaziya ama-photon adlula kukristalu.
Izicelo ze-Frontier ku-Optics
1. Ubuchwepheshe bokuphrojektha kwe-Holographic kanye nokubonisa
Ekuboniseni i-holographic, ukusetshenziswa kwama-modulators e-spatial optical ukulungisa kahle amaza okukhanya okwenzekayo kungenza amaza okukhanya aphazamise futhi aphazamiseke ngendlela ethile, akhe ukusatshalaliswa kwensimu yokukhanya okuyinkimbinkimbi. Isibonelo, i-SLM esekelwe ku-liquid crystal noma i-DMD ingalungisa ngokuguquguqukayo impendulo ye-optical yephikseli ngayinye, ishintshe okuqukethwe kwesithombe noma umbono ngesikhathi sangempela, okuvumela ababukeli ukuthi babone umphumela wesithombe onezinhlangothi ezintathu kusuka kuma-engeli ahlukene.
2. Insimu yokugcina idatha ye-Optical
Ubuchwepheshe bokugcina idatha ye-optical busebenzisa izici zokukhanya ezivame kakhulu nezinamandla aphezulu ukuze bufake ikhodi futhi buhlukanise ulwazi ngokusebenzisa ukuguqulwa kokukhanya okunembile. Lobu buchwepheshe buthembele ekulawulweni okunembile kwamagagasi okukhanya, okuhlanganisa ukulungiswa kwe-amplitude, isigaba kanye nesimo se-polarization, ukugcina idatha kuma-media afana nama-optical disc noma izinto zokugcina i-holographic. Ama-optical modulators, ikakhulukazi ama-spatial optical modulators, adlala indima ebalulekile ekuvumeleni ukulawula okunembile kakhulu kwezinqubo zokugcina nokufunda.
Esiteji sokukhanya, ama-photon afana nabadansi abahle kakhulu, edansa ngomusa “emculweni” wezinto ezifana namakristalu, amakristalu oketshezi kanye nemicu yokukhanya. Angashintsha isiqondiso, isivinini, futhi agqoke “izingubo ezinemibala” ehlukene ngokumangalisayo, aguqule ukunyakaza kwawo kanye nemisindo, futhi aveze ukusebenza okumangalisayo ngemva komunye. Lokhu kulawulwa okunembile kwama-photon kuyisihluthulelo somlingo esiphambili sobuchwepheshe be-optical besikhathi esizayo, okwenza umhlaba we-optical ugcwale amathuba angenamkhawulo.
