Mashandisirwo epamusoro-soro mu optics anotungamirwa nema optical modulators

Nheyo yemodulation yemazisoHazvina kuoma. Inonyanya kuita kuti chiedza chikwanise kuchinja amplitude, phase, polarization, refractive index, absorption rate nezvimwe zvinhu zvinoita kuti chiedza chishande kuburikidza ne external stimuli, kuti chitonge ma optical signal nemazvo, zvakaita sekugonesa ma photon kutakura nekutumira ruzivo. Zvinhu zvikuru zve common commonmodulator yemagetsi-opticzvinosanganisira zvikamu zvitatu: makristaro emagetsi, maerekitirodhi, uye zvinhu zvemaziso. Munguva yekugadziriswa kwechiedza, chinhu chiri mu optical modulator chinoshandura refractive index yaro, mwero wekunyudzwa kwechiedza nezvimwe zvinhu zvichikanganiswa nezvinokonzeresa zvekunze (zvakadai semagetsi, ruzha, shanduko dzekupisa kana masimba emakanika), nokudaro zvichikanganisa maitiro emaphoton sezvaanopfuura nepakati pechinhu, zvakaita sekudzora hunhu hwechiedza (amplitude, phase, polarization, nezvimwewo). Electro-optical crystal ndiyo musimboti wemodulator yemaziso, ine basa rekuita shanduko mumunda wemagetsi uye kuchinja refractive index yawo. Maelectrode anoshandiswa kuisa magetsi, nepo zvikamu zve optical zvakaita se polarizers nema waveplates zvichishandiswa kutungamira nekuongorora ma photon achipfuura nemukristaro.

Mashandisirwo eFrontier muOptics

1. Kufungidzira kweHolographic uye tekinoroji yekuratidza

Mukuongorora kwehorographic, kushandiswa kwema "spatial optical modulators" kugadzirisa zvakanaka mafungu echiedza chechiitiko kunogona kugonesa mafungu echiedza kupindira nekuparadzanisa nenzira chaiyo, zvichigadzira kugoverwa kwakaoma kwechiedza. Semuenzaniso, SLM yakavakirwa pa liquid crystal kana DMD inogona kugadzirisa mhinduro ye optical ye pixel yega yega, kuchinja zviri mukati memufananidzo kana maonero panguva chaiyo, zvichibvumira vaoni kuona mhedzisiro yemufananidzo kubva kumativi akasiyana.

2. Munda wekuchengetera data reOptical

Tekinoroji yekuchengetedza data reOptical inoshandisa hunhu hwechiedza hune mafrequency akawanda uye simba rakawanda kuti inyore uye inzwisise ruzivo kuburikidza nekuchinja kwechiedza kwakaringana. Tekinoroji iyi inotsamira pakudzora kwakaringana kwemafungu echiedza, kusanganisira kugadzirisa amplitude, phase uye polarization state, kuchengetedza data pane media dzakadai sema optical discs kana holographic storage materials. Ma optical modulators, kunyanya spatial optical modulators, anoita basa rakakosha mukubvumira kudzora kwakaringana kwe optical pamusoro pemaitiro ekuchengetedza nekuverenga.

Pachikuva chemaziso, maphoton akafanana nevatambi vakanaka, vachitamba zvine runako vachitevedzera "rwiyo" rwezvinhu zvakaita semakristaro, makristaro emvura uye mafiber emaziso. Vanogona kuchinja divi, kumhanya, uye kutopfeka "zvipfeko zvemavara" zvakasiyana, vachichinja mafambiro avo nemitinhimira, uye vachiratidza mashandiro anoshamisa mushure meimwe. Kudzora uku kwakarurama kwemaphoton ndiyo kiyi yemashiripiti yehunyanzvi hwemazuva ano hwemaoptical, zvichiita kuti nyika yemaziso izere nemikana isingaperi.
