Modulator-ka elektiroonigga ah (EOM) ayaa koontaroolaya awoodda, marxaladda iyo polarization ee laydhka laysarka isaga oo si elektaroonig ah u xakameynaya calaamadda.
Modulator-ka ugu fudud ee korantada-optic-ga waa modulator-ka wejiga oo ka kooban hal sanduuq oo Pockels ah, halkaas oo beer koronto (oo lagu dabaqay crystal by electrode) uu beddelo daahitaanka wajiga laysarka ka dib marka uu galo crystal. Xaaladda kala-soocidda ee iftiinka dhacdada badanaa waxay u baahan tahay inay la mid noqoto mid ka mid ah faashashka indhaha ee crystal si xaaladda polarization ee laydhka uusan isbeddelin.
Xaaladaha qaarkood waxa loo baahan yahay oo kaliya habaynta wajiga aadka u yar (muddo ama xilliyeed) Tusaale ahaan, EOM waxaa badanaa loo isticmaalaa in lagu xakameeyo oo lagu dejiyo inta jeer ee soo noqnoqda ee resonators indhaha. Modulators resonance waxaa inta badan loo isticmaalaa xaaladaha habaynta xilliyeedka loo baahan yahay, iyo qoto dheer modulation waxaa lagu heli karaa oo kaliya korontad dhexdhexaad ah wadista. Mararka qaarkood qoto-dheeraanta qaabeynta ayaa aad u weyn, iyo dhinacyo badan oo dhinac ah (dhaliye shanlo fudud, shanlo iftiin) ayaa lagu soo saaraa spectrum.
Modulator-ka polarization
Iyadoo ku xiran nooca iyo jihada kristanta aan tooska ahayn, iyo sidoo kale jihada korantada dhabta ah, dib u dhigista marxaladda ayaa sidoo kale la xiriirta jihada polarization. Sidaa darteed, sanduuqa Pockels wuxuu arki karaa taarikada mowjadaha badan ee korantada ee kontaroolada, waxaana sidoo kale loo isticmaali karaa in lagu beddelo dawladaha polarization. Iftiinka gelinta toosan (sida caadiga ah xagal 45° ka soo jeeda dhidibka crystal), polarization of beam soosaarku waa caadi ahaan elliptical, halkii si fudud uu ugu rogi lahaa xagal ka yimid iftiinka toosan ee asalka ah.
Modulator weyn
Marka lagu daro walxaha kale ee indhaha, gaar ahaan polarizers, sanduuqyada Pockels waxaa loo isticmaali karaa noocyada kale ee wax-ka-beddelka. Modulator-ka weyn ee Jaantuska 2 wuxuu adeegsadaa sanduuqa Pockels si uu u beddelo xaaladda polarization-ka, ka dibna wuxuu adeegsadaa polarizer si uu isbeddelka gobolka polarization ugu beddelo isbeddel ku yimaadda baaxadda iyo awoodda iftiinka la kala qaado.
Qaar ka mid ah codsiyada caadiga ah ee modulators electro-optic waxaa ka mid ah:
Wax ka beddelka awoodda laydhka laysarka, tusaale ahaan, daabacaadda laysarka, duubista xogta xawaaraha sare leh, ama isgaadhsiinta indhaha xawaaraha sare leh;
Loo isticmaalo hababka xasilinta inta jeer ee laysarka, tusaale ahaan, iyadoo la adeegsanayo habka Pound-Drever-Hall;
Q waxay ku bedeshaa laysarka gobolka adag (halka EOM loo isticmaalo in lagu xidho resonator laser ka hor shucaaca garaaca);
Qaabka firfircoon ee quful (EOM modulation cavity luminta ama wajiga iftiinka safarka wareega, iwm.);
Bedelida garaaca garaaca garaaca garaaca wadnaha, cod-weyneyaasha jawaab celinta togan iyo leysarka leexleexa.
