1. I-MER ibhekisa kwi-Modulator Extinction Ratio. Umlinganiselo wokutshabalala ophunyeziweyo uqhelekile ngumlinganiselo wokuphela kwemodyuli echazwe kwidatha yemodyuli.
2. Nceda uqaphele ukuba i-input optical power ayihambelani namandla okukhanya kwindawo ekhethiweyo ye-bias point. Ibhekisa kumandla okukhanya aphezulu anokuthi imodyuli iwathumele kwisilawuli xa amandla ombane acalanye asuka ku- −Vπ ukuya ku +Vπ.

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.
I-Rofea Optoelectronics ibonelela ngomgca wemveliso yeemodyuli ze-Electro-optic, iimodyuli zeSigaba, imodyuli yokuqina, iiFotodetectors, imithombo yokukhanya kweLaser, ii-laser zeDFB, iiamplifiers zamehlo, i-EDFA, i-SLD laser, i-QPSK modulation, iPulse laser, isitshini sokukhanya, i-Balanced driver photodetector, iLaser. , I-Fiber optic amplifier, imitha yamandla okukhanya, i-Broadband laser, i-laser ye-Tunable, i-Optical detector, i-Laser diode driver, i-Fiber amplifier. Sikwabonelela ngeemodyuli ezininzi zokwenziwa ngokwezifiso, ezinje nge-1 * 4 uluhlu lweemodyuli zesigaba, i-Vpi ephantsi kakhulu, kunye ne-ultra-high extinction ratio modulators, ezisetyenziswa ikakhulu kwiiyunivesithi nakumaziko.
Ndiyathemba ukuba iimveliso zethu ziya kuba luncedo kuwe nakuphando lwakho.
