Izinhlelo zokusebenza ezisezingeni eliphezulu kuma-optics aholwa ama-optical modulators
Umgomo weukuguqulwa kwe-opticalayiyona inkimbinkimbi. Ngokuyinhloko ifinyelela ukuguquguquka kwe-amplitude, isigaba, i-polarization, inkomba ye-refractive, izinga lokumunca nezinye izici zokukhanya ngokusebenzisa izisusa zangaphandle, ukulawula ngokunembile isignali ye-optical, njengokwenza ama-photon akwazi ukuthwala nokudlulisa ulwazi. Izingxenye eziyisisekelo ze-commoni-electro-optic moduleIhlanganisa izingxenye ezintathu: amakristalu e-electro-optic, ama-electrode, nezinto ezibonakalayo. Phakathi nenqubo yokuguqulwa kokukhanya, izinto eziku-modulator ye-optical zishintsha inkomba yayo ye-refractive, izinga lokumunca nezinye izakhiwo ngaphansi kwethonya le-stimuli yangaphandle (njengamasimu kagesi, izinkundla zomsindo, izinguquko ezishisayo noma amandla omshini), ngaleyo ndlela kuthinte ukuziphatha kwama-photons njengoba edlula ezintweni, njengokulawula izici zokusabalalisa, isigaba sokukhanya, njll. Ikristalu ye-electro-optical iwumgogodla we-imoduli ye-optical, enesibopho sokuphendula izinguquko endaweni kagesi kanye nokuguqula inkomba yayo ye-refractive. Ama-Electrode asetshenziselwa ukusebenzisa izinkambu zikagesi, kuyilapho izakhi zokukhanya ezifana nama-polarizer nama-waveplates asetshenziselwa ukuqondisa nokuhlaziya ama-photon adlula kukristalu.
Izicelo ze-Frontier ku-Optics
1.I-Holographic projection kanye nobuchwepheshe bokubonisa
Ku-holographic projection, ukusetshenziswa kwamamoduli okukhanya kwendawo ukuze kulungiswe kahle amaza okukhanya kwesigameko kungenza amaza okukhanya aphazamise futhi aphazamise ngendlela ethile, enze ukusabalalisa kwensimu yokukhanya okuyinkimbinkimbi. Isibonelo, i-SLM esekelwe ku-liquid crystal noma i-DMD ingashintsha ngokushintshashintshayo impendulo yokubona kwephikseli ngayinye, iguqule okuqukethwe kwesithombe noma umbono ngesikhathi sangempela, ivumele ababukeli ukuthi babone umphumela wesithombe-ntathu wesithombe ngama-engeli ahlukene.
2.Indawo yokugcina idatha ye-Optical
Ubuchwepheshe bokugcinwa kwedatha obubonakalayo busebenzisa izici zokukhanya zemvamisa ephezulu namandla aphezulu ukuze kuhlanganiswe futhi kuqondwe ulwazi ngokushintshashintsha kokukhanya okunembile. Lobu buchwepheshe buncike ekulawuleni okunembile kwamaza okukhanya, okuhlanganisa ukulungiswa kwe-amplitude, isigaba kanye nesimo se-polarization, ukugcina idatha kumidiya efana nama-optical discs noma izinto zokugcina i-holographic. Amamojula abonakalayo, ikakhulukazi amamojula okukhanya kwendawo, adlala indima ebalulekile ekuvumeleni ukulawula okunembe kakhulu kwezinqubo zokugcina nokufunda.
Esiteji se-optical, ama-photon afana nabadansi abahle, abadansela ngomusa "umculo" wezinto ezinjengamakristalu, amakristalu angama-liquid nama-optical fibers. Bangakwazi ukushintsha kahle indlela, isivinini, futhi bagqoke ngokushesha "izingubo ezinemibala", baguqule ukunyakaza kwabo nesigqi, futhi bethule ukusebenza okumangalisayo ngemva kokunye. Lokhu kulawula okunembile kwama-photons kuwukhiye womlingo wokuphela kobuchwepheshe besikhathi esizayo, okwenza umhlaba obonakalayo ugcwale amathuba angapheli.
