Xakamaynta eexda IQ Modulator Is haysta oo toos ah Xakamaynta Eexda

Sharaxaad Gaaban:

Xakamaynta eexda modulator Rofea' waxaa si gaar ah loogu talagalay modulators Mach-Zehnder si loo hubiyo xaalad hawlgal oo xasiloon oo ka jirta jawiga hawlgalka ee kala duwan.Iyada oo ku saleysan habka hab-samaynta calaamadaha digitized oo dhamaystiran, koontarooluhu waxa uu bixin karaa hawl qabad aad u deggan.

Kantarooluhu waxa uu isku duraa soo noqnoqoshada hooseeya, calaamada ballaadhinta hoose oo ay weheliso danab eex ah modulator-ka.Waxay sii akhrinaysaa wax-soo-saarka modulator-ka waxayna go'aamisaa xaaladda korantada eexda iyo khaladka la xiriira.Danab eexeed cusub ayaa lagu dabaqi doonaa kelmado ka dib iyadoo loo eegayo cabbirkii hore.Sidan, modulator-ka ayaa la hubiyaa inuu ku shaqeynayo korantada eexda ee habboon.

1. MER waxaa loola jeedaa Modulator Extinction Ratio.Saamiga dabar goynta la gaarey waa sida caadiga ah saamiga baabi'inta modulator-ka ee lagu qeexay xaashida xogta modulator-ka.
2. Fadlan la soco in galinta awooda indhaha aanu u dhigmin awooda indhaha ee barta eexda la doortay.Waxay tilmaamaysaa awoodda indhaha ee ugu badan ee modulator-ku u dhoofin karo kantaroolaha marka korantada eexdu u dhexayso -Vπ ilaa +Vπ .

1 Polar waxay kuxirantahay nidaamka RF signal.Marka aysan jirin calaamadda RF ee nidaamka, cirifku waa inuu noqdaa mid togan.Marka signalka RF uu leeyahay baaxad weyn oo ka weyn heer cayiman, dabaysha ayaa ka beddeli doonta togan una beddelmi doonta taban.Waqtigan xaadirka ah, Null point iyo dhibicda ugu sarreysa ayaa midba midka kale isweydaarsan doona. Q+ dhibic iyo Q- dhibic sidoo kale way isweydaarsanayaan.

si toos ah iyada oo aan la beddelin dhibcaha hawlgalka.

2Kaliya hal doorasho ayaa la doortaa inta u dhaxaysa isticmaalka kontoroolka photodiode ama isticmaalka modulator photodiode.Waxaa lagu talinayaa in loo isticmaalo kontoroolka photodiode ee tijaabooyinka shaybaadhka laba sababood dartood.Marka hore, kontaroolaha photodiode ayaa xaqiijiyay tayada.Marka labaad, way sahlan tahay in la hagaajiyo xoogga iftiinka wax gelinta. Haddii la isticmaalayo modulator's photodiode gudaha, fadlan hubi in hadda soo-saarka photodiode uu si adag u siman yahay awoodda wax-gelinta.
