Rof Bias Point Controller automatic bias control module of lithium niobate MZ imodyuli

Inkcazelo emfutshane:

I-ROF-ABC-MZ uchungechunge oluzenzekelayo lwemodyuli yokulawula i-bias isetyenziselwa ulawulo oluzenzekelayo lwe-lithium niobate imodyuli ye-MZ, enokwenza imodyuli isebenze ngokuzinzileyo kwindawo ephantsi, inqanaba eliphezulu okanye indawo ye-orthogonal (ummandla womgca). Imodyuli idityaniswe kunye ne-1/99 coupler, enokulawula ukutshintshwa kwendawo yokusebenza ngokusebenzisa i-port ye-serial yangaphandle, kwaye ixhasa imowudi yohlengahlengiso lwe-manual, efanelekileyo kwiimodyuli ezahlukeneyo ze-wavelength kunye nezicelo, kwaye ifaneleke kakhulu. iilabhoratri zeyunivesithi ukwakha imifuniselo yedesktop.

Phawula:

I-1* ibhekisa kuluhlu lwamandla igalelo kwimodyuli xa imveliso yemodyuli iphezulu. Kwinqanaba eliphantsi lolawulo lwemodyuli enomlinganiselo ophezulu wokuphela, amandla okufakwayo kufuneka anyuswe ngokufanelekileyo; Ngeemfuno ezikhethekileyo zokufakwa kwamandla, unokuhlengahlengisa i-coupler yangaphakathi kunye ne-detector gain indicators, nceda uqhagamshelane neentengiso xa ubeka ii-odolo.

I-2 * Xa ubeka umyalelo, nceda ucacise i-wavelength yokusebenza, efuna ukulungiswa ngokuhambelana nobude bokusebenza.

I-3 * yokutshintsha ukutshatyalaliswa komlinganiselo kuxhomekeke kwinqanaba lokutshintsha kokuphela kwemodyuli ngokwayo.

1 Ipolar ixhomekeke kwisignali ye-RF yesixokelelwano. Xa kungekho mqondiso weRF kwisixokelelwano, i-polar kufuneka ibe ntle. Xa isignali yeRF ine-amplitude enkulu kunomgangatho othile, i-polar iya kutshintsha ukusuka ku-positive ukuya ku-negative. Ngeli xesha, i-Null point kunye ne-Peak point iya kutshintshela enye kwenye.Inqaku le-Q + kunye ne-Q-point iya kutshintshela kunye.

ngqo ngaphandle kokutshintsha iindawo zokusebenza.

2Inye kuphela ukhetho oluya kunyulwa phakathi kokusebenzisa isilawuli sefotodiode okanye ukusebenzisa imodyuli yefotodiode. Kuyacetyiswa ukuba usebenzise isilawuli sefotodiode kwimifuniselo yeLab ngezizathu ezibini. Okokuqala, isilawuli se-photodiode siqinisekise iimpawu. Okwesibini, kulula ukunyenyisa igalelo ukukhanya intensity.Ukuba usebenzisa imodyuli yangaphakathi photodiode, nceda uqinisekise ukuba imveliso yangoku ye photodiode ngokungqongqo ngokomlinganiselo amandla igalelo.
