Ukusetyenziswa kwe-cutting-edge kwi-optics ekhokelwa yi-optical modulators

Umgaqo weukumodareyitha kwamehloayintsonkothanga. Ikakhulu ifezekisa ukumodareyitha kwe-amplitude, isigaba, i-polarization, i-index ye-refractive, izinga lokufunxa kunye nezinye iimpawu zokukhanya ngokusebenzisa i-stimuli yangaphandle, ukulawula ngokuchanekileyo umqondiso we-optical, njengokwenza ukuba iifotoni zithwale kwaye zidlulise ulwazi. Amalungu asisiseko aqhelekileyoimodyuli ye-electro-opticziquka iindawo ezintathu: iikristale ze-electro-optic, i-electrode, kunye nezinto ezibonakalayo. Ngethuba lenkqubo yokuguqulwa kokukhanya, izinto eziphathekayo kwi-modulator ye-optical zitshintsha isalathisi sayo se-refractive, izinga lokufunxa kunye nezinye iimpawu eziphantsi kwefuthe le-stimuli yangaphandle (njengamabala ombane, imimandla yomsindo, utshintsho lwe-thermal okanye amandla omatshini), ngaloo ndlela ichaphazela ukuziphatha kweefotoni njengoko zidlula kwizinto eziphathekayo, ezifana nokulawula iimpawu zokusabalalisa, i-polar, i-polartuation, njl. Ikristale ye-electro-optical ngundoqo weimodyuli yokubona, uxanduva lokuphendula utshintsho kwintsimi yombane kunye nokuguqula isalathisi sayo se-refractive. I-Electrodes isetyenziselwa ukusebenzisa imimandla yombane, ngelixa izinto ezibonakalayo ezifana ne-polarizers kunye ne-waveplates zisetyenziselwa ukukhokela kunye nokuhlalutya kweefotoni ezidlula kwi-crystal.

Ukusetyenziswa kweFrontier kwi-Optics

I-1.Holographic projection kunye neteknoloji yokubonisa

Kwintelekelelo yeholographic, ukusetyenziswa kweemodyuli ze-spatial optical modulators ukumodareyitha kakuhle isiganeko samaza okukhanya kunokwenza ukuba amaza okukhanya aphazamise kwaye aphazamise ngendlela ethile, enze ukuhanjiswa kwentsimi yokukhanya okuntsonkothileyo. Ngokomzekelo, i-SLM esekwe kwikristale yolwelo okanye i-DMD inokutshintsha ngokuguquguqukayo impendulo ye-pixel nganye, itshintshe umxholo womfanekiso okanye imbono ngexesha langempela, ivumela ababukeli ukuba bajonge isiphumo se-dimensional emithathu yomfanekiso kwii-engile ezahlukeneyo.

I-2.Indawo yokugcina idatha ye-Optical

Itekhnoloji yokugcinwa kwedatha ye-Optical isebenzisa i-high-frequency kunye ne-high-energy features of light to encode and decode decode information through the specific modulation light. Le teknoloji ixhomekeke kulawulo oluchanekileyo lwamaza okukhanya, kubandakanywa ukulungiswa kwe-amplitude, isigaba kunye ne-polarization state, ukugcina idatha kumajelo afana neediski ze-optical okanye izinto zokugcina i-holographic. Iimodyuli zamehlo, ngakumbi iimodareyitha zamehlo ezikwisithuba, zidlala indima ebalulekileyo ekuvumeleni ulawulo oluchanekileyo oluchanekileyo kwiinkqubo zokugcina nokufunda.

Kwinqanaba le-optical stage, iiphotons zifana nabadanisi abagqwesileyo, bedanisa ngobubele “kwingoma” yezixhobo ezifana neekristale, iikristale zolwelo kunye neefiber zamehlo. Bangakwazi ukutshintsha indlela, isantya, kwaye ngoko nangoko banxibe "iimpahla ezinemibala", baguqule iintshukumo zabo kunye nesingqisho, kwaye babonise ukusebenza okumangalisayo emva kwenye. Olu lawulo luchanekileyo lweefotoni ngokuchanekileyo sisitshixo somlingo kwi-cut-edge yetekhnoloji ye-optical yexesha elizayo, okwenza umhlaba obonakalayo uzaliswe ngamathuba angenasiphelo.
