Maɓallan mahimmanci naMai daidaita Mach Zehnder
Mach Zehnder Modulator (MZM Modulator) babban na'ura ce ta zamani.na'urar auna ƙarfin lantarki ta lantarki (electro-optical extensive modulator)An haɓaka shi bisa ga ƙa'idar kutse ta gani. Yana cikin wani muhimmin reshe nadaidaitawar lantarkia cikin tsarin fasahar daidaita hasken haske. A halin yanzu, ana shirya manyan samfuran ta amfani da fasahar jagorar hasken haske ta lithium niobate (LiNbO3). Tare da fa'idodin aiki guda uku na ƙarancin chirp, rabon ƙarewa mai yawa, da kuma babban bandwidth na daidaitawa, ya zama samfurin daidaitawa mai ma'ana a fannoni na sadarwa mai nisa na fiber optic, sadarwa mai haɗin kai, samar da tsefe na mitar gani, da tsarin laser mai sauri.
1, Maɓallan mahimmanci:
1.1 Tsawon zangon aiki: 1310nm/1550nm shine babban zaɓi a fannin sadarwa a yanzu
1.2 Ƙarfin wutar lantarki na rabin raƙuman ruwa V π: Samfuran jagorar raƙuman ruwa na kasuwanci gabaɗaya ana sarrafa su a cikin 5V. Ƙasan ƙarfin wutar lantarki na rabin raƙuman ruwa, ƙarancin farashin tuƙi na na'urar da ta dace
1.3 Bawul ɗin daidaitawa: A halin yanzu, samfuran kasuwanci galibi an raba su zuwa matakai daban-daban na 40G/80G/120GHz;
1.4 Rabon Karewa: Rabon Karewa na kayayyaki masu inganci na iya kaiwa sama da 25dB, tare da aiki mafi kyau fiye da EAM
1.5 Asarar shigarwa: Matsakaicin ƙimar yana cikin kewayon 3~4.5dB;
1.6 Chirp Coefficient: Kayayyakin da ke da kyakkyawan aiki za su iya cimma kusan babu chirp, wanda shine babban fa'idarsu ta musamman a cikin yanayin watsawa mai nisa.
2. Rarraba Samfura:
2.1 Ta hanyar yanayin tuƙi: daidaita hannu ɗaya, daidaita turawa da jan hannu biyu (babban tsari a fagen sadarwa, tare da mafi kyawun layi);
2.2 Ta hanyar aiki: Ƙarfin yau da kullunMai Gyaran MZM, Mai Haɗa MZM Mai Haɗa IQ (wanda aka keɓe don sadarwa mai haɗin kai, wanda aka haɗa ta hanyar Mai Haɗa MZM mai haɗin kai biyu.
2.3 Kayayyakin kasuwanci galibi suna dogara ne akan tsarin jagorar raƙuman ruwa da aka haɗa, daidaita aiki da kwanciyar hankali na samar da taro.

3. Yanayin aikace-aikace:
Rufe hanyoyin sadarwa na baya-bayan nan na 400G/800G/1.6T, na'urorin hangen nesa na nesa masu tsari, na'urar gano radar/fiber mai kama da juna, tsarin kullewa/tsarin tsefewar mitar gani mai sauri, sarrafa matakin sadarwa na kwantum da sauran fannoni.
4. Yanayin ci gaba:

Ci gaba zuwa ga rage girman sinadarin lithium niobate mai sirara na MZM modulator da kuma samar da kayan aiki masu haɗakar MZM bisa silicon, cimma rage farashi da inganta inganci, da kuma faɗaɗa ƙarin yanayin aikace-aikace.
