Xuduudaha muhiimka ah ee modulator-ka Mach Zehnder

Xuduudaha muhiimka ah eeMach Zehnder modulator
Mach Zehnder Modulator (MZM Modulator) waa qalab casri ah oo casri ah oo loogu talagalay in lagu kordhiyo waxqabadka qalabka.modulator xoojinta elektaroonigga ahWaxaa lagu sameeyay mabda'a faragelinta indhaha. Waxay ka tirsan tahay laan muhiim ah oohabaynta elektaroonigga ahnidaamka tiknoolajiyada isbeddelka indhaha. Waqtigan xaadirka ah, alaabada caadiga ah waxaa lagu diyaariyaa iyadoo la adeegsanayo tiknoolajiyada hagaha hirarka indhaha ee lithium niobate (LiNbO3). Iyada oo leh saddexdeeda faa'iido ee waxqabadka asaasiga ah ee jajabka aadka u hooseeya, saamiga baabi'inta aadka u sarreeya, iyo baaxadda isbeddelka aadka u weyn, waxay noqotay badeecad wax-ka-beddel halbeeg ah oo la aqoonsan yahay oo ku saabsan isgaarsiinta fiber optic ee laf-dhabarta fog, isgaarsiinta indhaha ee isku-dhafan, soo saarista shanlada soo noqnoqda ee indhaha, iyo nidaamyada laysarka aadka u degdega ah.
1, Xuduudaha Muhiimka ah:
1.1 Mowjadda shaqada: 1310nm/1550nm hadda waa doorashada ugu weyn ee dhinaca isgaarsiinta
1.2 Danabka badh-hirka V π: Badeecadaha hagaha ganacsiga waxaa guud ahaan lagu xakameeyaa gudaha 5V. Danabka badh-hirka ee hooseeya, ayaa kharashka wadista ee qalabka u dhigma uu hoos u dhacayaa
1.3 Baaxadda isbeddelka: Waqtigan xaadirka ah, badeecadaha ganacsiga waxaa inta badan loo qaybiyaa heerar kala duwan oo ah 40G/80G/120GHz;
1.4 Saamiga dabar-goynta: Saamiga dabar-goynta ee alaabada tayada sare leh waxay gaari kartaa in ka badan 25dB, iyadoo waxqabadku aad uga sarreeyo EAM
1.5 Lumitaanka gelinta: Qiimaha caadiga ah wuxuu ku jiraa xadka 3~4.5dB;
1.6 Chirp Coefficient: Badeecadaha leh waxqabad aad u wanaagsan waxay gaari karaan ku dhawaad ​​eber chip, taas oo ah faa'iidada ugu weyn ee gaarka ah ee xaaladaha gudbinta masaafada dheer.
2. Kala soocidda Badeecada:
2.1 Habka wadista: habaynta hal gacan, habaynta riix-jiidista laba-geesoodka ah (dhexdhexaadka goobta isgaarsiinta, oo leh qaab toosan oo wanaagsan);
2.2 Shaqada: Xoogga caadiga ahMZM Modulator, IQ-ga isku-dhafan ee MZM Modulator (oo loogu talagalay isgaarsiinta isku-dhafan, oo ay isku-dhafan yihiin Modulator MZM dual orthogonal.
2.3 Badeecadaha ganacsiga waxay inta badan ku salaysan yihiin habaynta hagaha hirarka ee isku dhafan, dheellitirka waxqabadka iyo xasilloonida wax soo saarka tirada badan.

3. Xaaladaha codsiga:
Daboolida shabakadda laf-dhabarta 400G/800G/1.6T modules-ka indhaha ee masaafada dheer, dareemaha radar-ka indhaha ee isku-dhafan/fiber-ka, qufulka qaabka laysarka ee aadka u degdega badan/diyaarinta shanlada soo noqnoqoshada indhaha, xakamaynta wejiga isgaarsiinta quantum iyo meelaha kale.
4. Isbeddelka horumarinta:

Horumarinta yareynta lithium niobate-ka filimka khafiifka ah ee MZM modulator iyo soo saarista tirada badan ee modulators-ka MZM ee ku salaysan silicon, gaarista dhimista kharashka iyo horumarinta hufnaanta, iyo ballaarinta xaalado codsi oo badan.
