Codsiga tikniyoolajiyadda eeQalabka elektro-optictic

AQOONSIGA EVRO-OPTICEom modulator) Waa shey xakameyn ah oo xakameyn ah oo adeegsanaya saameynta elektaroonigga ah ee is-beddelka ah si loo yareeyo nambarka iftiinka. Mabda 'shaqadeeda ayaa guud ahaan lagu gaaraa saameynta jeebka (jeebka saamaynta, oo ah kuwa jeebka, oo ka faa'iideysanaya ifafaale in tusmada ugu badan ee qalabka indhaha ee aan tooska ahayn ay isbedelaan tallaabada korantada.

Qaab-dhismeedka aasaasiga ah ee modulator-ka korantada ee elektro-optic waxaa ku jira crystal (jeexan oo ku yaallo) oo leh saameyn elektaroonig ah, iyo maaddada caanka ah waa litheium ninoobate (linbo₃). Korontada loo baahan yahay in lagu dhiirrigeliyo isbedelka wejiga waxaa loo yaqaan koronto nus-mowduuc. Wixii jeebbooyin ah, boqol-hoosaad ama xitaa kumanaan volts ah ayaa sida caadiga ah loo baahan yahay, sidaa darteed baahida loo qabo cottatifers-ka-koranta sare. Wareegtada elektiroonigga ah ee ku habboon ayaa korantada sare u beddeli kara dhawr nanoseconds, oo u oggolaanaya eOM in loo isticmaalo sida ugu wareejinta indhaha ee ugu wanaagsan; Sababo la xiriira dabeecadda bannaanka ee jeebka, darawalladaas waxay u baahan yihiin inay bixiyaan tiro aad u badan oo ah hadda (marka la eego wareejinta degdegga ah ama isbedelka, cufan waa in loo yareeyaa si loo yareeyo lumista tamarta). Xaaladaha kale, sida marka ay kaliya ama isbadal wareysa oo keliya loo baahan yahay, kaliya koronto yar ayaa looga baahan yahay isbedelka. Agabyada kale ee aan tooska ahayn ee aan tooska ahayn ee loo adeegsado ee ku jira modulator-ka indhaha ah (Eom modulator) Ku dar titassium titassium (ktp), beta-barium Bograte (BBO, oo ku habboon celceliska korantada sareeya iyo / ama tittooium tosphate (NH4H2phate), ADP, oo leh guri elektro4 ah.

Modulator elektaroonig ah (EO modulator) Muuji arji muhiim ah oo arji muhiim ah oo ah tiro ka mid ah meelaha teknolojiyada-sare:

1. Xiriirka fiber ee indhaha:EO modulator) Waxaa loo isticmaalaa in lagu habeeyo calaamadaha indhaha, iyadoo la hubinayo gudbinta macluumaadka hufan ee la isku halleyn karo ee masaafada dheer. Iyaga oo si sax ah u xakameynaya wejiga ama iftiinka iftiinka, xadka xawaaraha sare iyo awooda-sare waa la gaari karaa.

2. Si sax ah u eg muraayadda hore ee elektro-optrotic modulator wuxuu kaqeyb qaadanayaa isha iftiinka ee muuqaalka ah si loo wanaajiyo saxsanaanta cabbiraadda. Adigoo si dhakhso leh uqeyb qaadanaya soo noqnoqda ama wajiga calaamadaha indhaha, falanqaynta iyo aqoonsashada qaybaha kiimikada ee isku murugsan waa la taageeri karaa, xallinta iyo xalinta casharka muuqaalka muuqaalka ayaa la hagaajin karaa.

3. Xog-tilmaameedka Wax-ka-qabashada Waxqabadka Sare: Beddelka Electro-Electro-opute ee ku jira xisaabinta iyo nidaamka xog-haynta xogta, iyada oo loo marayo isbadal ku saabsan calaamadaha indhaha si loo wanaajiyo xawaaraha socodka xogta iyo dabacsanaanta. Iyada oo leh dabeecadaha jawaab celinta degdegga ah ee eom, xawaare sare iyo xog-yar-yar oo ku saabsan ka baaraandegista iyo gudbinta xogta indhaha ee hoose iyo faafinta waa la xaqiijin karaa.

4. Teknolojiyadda laser: Qalabka korantada ee elektro-optro-optro waxay xakameyn kartaa wajiga iyo codkarka laseed ee laamiga la denka, iyadoo la siin karo taageero sawirro sax ah, ka baaraandegyada laser iyo codsiyada kale. Iyaga oo si sax ah uqeyb qaadanaya cabbirrada xaraashka laser-ka, oo tayo sare leh oo laser ah ayaa lagu gaari karaa.
