Izicelo eziphambili kwi-optics ezikhokelwa zii-optical modulators

Umgaqo weukuguquguquka kokukhanyaayinzima. Ngokuyintloko ifezekisa ukuguquguquka kwe-amplitude, i-phase, i-polarization, i-refractive index, i-absorption rate kunye nezinye iimpawu zokukhanya nge-external stimuli, ukulawula ngokuchanekileyo i-optical signal, njengokuvumela ii-photons ukuba zithwale kwaye zidlulise ulwazi. Izinto ezisisiseko ze-commoni-electro-optic modulatorziquka iindawo ezintathu: iikristale ze-electro-optic, ii-electrode, kunye nezinto ze-optical. Ngexesha lenkqubo yokuguqulwa kokukhanya, izinto ezikwi-optical modulator zitshintsha i-refractive index yazo, izinga lokufunxwa kunye nezinye iimpawu phantsi kwempembelelo yezinto zangaphandle (ezifana namacandelo ombane, amasimi esandi, utshintsho lobushushu okanye amandla oomatshini), ngaloo ndlela zichaphazela indlela eziziphatha ngayo ii-photon njengoko zidlula kwizinto, njengokulawula iimpawu zokusasazeka kokukhanya (amplitude, phase, polarization, njl.njl.). I-electro-optical crystal yintloko yei-modulator yokukhanya, inoxanduva lokuphendula kutshintsho olukwintsimi yombane kunye nokutshintsha isalathisi sayo sokurhawuzelela. Ii-electrode zisetyenziselwa ukusebenzisa amasimi ombane, ngelixa izinto ezibonakalayo ezifana neepolarizers kunye nee-waveplates zisetyenziselwa ukukhokela nokuhlalutya ii-photons ezidlula kwikristale.

Izicelo zeFrontier kwi-Optics

1. Uqikelelo lweHolographic kunye netekhnoloji yokubonisa

Kwi-holographic projection, ukusetyenziswa kwee-spatial optical modulators ukulungisa kakuhle amaza okukhanya okwenzekayo kunokwenza amaza okukhanya aphazamise kwaye aphazamiseke ngendlela ethile, enze usasazo oluntsonkothileyo lwentsimi yokukhanya. Umzekelo, i-SLM esekelwe kwi-liquid crystal okanye i-DMD inokulungisa ngokuguquguqukayo impendulo ye-optical ye-pixel nganye, itshintshe umxholo womfanekiso okanye umbono ngexesha langempela, ivumela ababukeli ukuba babone isiphumo se-three-dimensional somfanekiso kwii-engile ezahlukeneyo.

2. Intsimi yokugcina idatha ye-Optical

Iteknoloji yokugcina idatha ye-optical isebenzisa iimpawu zokukhanya ezisebenza rhoqo kakhulu kunye namandla aphezulu ukuze i-encode kwaye ichaze ulwazi ngokusebenzisa i-modulation yokukhanya echanekileyo. Le teknoloji ixhomekeke kulawulo oluchanekileyo lwamaza okukhanya, kubandakanya ukulungiswa kwe-amplitude, isigaba kunye ne-polarization state, ukugcina idatha kwimidiya efana neediski ze-optical okanye izixhobo zokugcina i-holographic. Ii-optical modulators, ngakumbi ii-spatial optical modulators, zidlala indima ebalulekileyo ekuvumeleni ulawulo oluchanekileyo kakhulu lwe-optical kwiinkqubo zokugcina nokufunda.

Kwiqonga le-optical, ii-photon zifana nabadanisi ababalaseleyo, bedanisa ngobuhle "kwingoma" yezinto ezifana neekristale, iikristale zolwelo kunye neefayibha ze-optical. Banokutshintsha indlela, isantya, baze banxibe "iimpahla ezinemibala" ezahlukeneyo ngoko nangoko, batshintshe iintshukumo zabo kunye ne-rhythm, kwaye babonise ukusebenza okumangalisayo emva komnye. Olu lawulo luchanekileyo lwee-photon luyisitshixo somlingo kwitekhnoloji ye-optical yexesha elizayo, okwenza ihlabathi le-optical lizaliswe ngamathuba angenamkhawulo.
