I-MER engu-1 ibhekisela ku-intrinsic Modulator Extinction Ratio. I-extinction ratio efinyelelwayo ngokuvamile iyi-extinction ratio ye-modulator echazwe kudatha ye-modulator.
2AkeVπ bonisa i-voltage ye-bias ku-180◦ futhiVP bonisa i-voltage ye-bias elungiselelwe kakhulu kuma-Quad points.
3Sicela uqaphele ukuthi amandla okukhanya okufakwayo awabhekiseli emandleni okukhanya endaweni ekhethiwe ye-bias. Amandla okukhanya aphezulu kakhulu i-modulator engawathumela kumlawuli lapho i-bias voltage isukela ku-−Vπ kuya ku-+Vπ .

1 I-Polar incike esignalini ye-RF yesistimu. Uma kungekho signali ye-RF ohlelweni, i-polar kufanele ibe yinhle. Uma isignali ye-RF inobukhulu obukhulu kunezinga elithile, i-polar izoshintsha isuka kokuhle iye kokubi. Ngalesi sikhathi, iphuzu le-Null kanye nephuzu le-Peak zizoshintshana. Iphuzu le-Q+ kanye nephuzu le-Q nazo zizoshintshana. I-Polar switch ivumela umsebenzisi ukushintsha
i-polar ngqo ngaphandle kokushintsha amaphuzu okusebenza.

1 Kuzokhethwa ukhetho olulodwa kuphela phakathi kokusebenzisa i-photodiode yokulawula noma ukusebenzisa i-photodiode yokulawula. Kunconywa ukusebenzisa i-photodiode yokulawula ekuhlolweni kwelebhu ngezizathu ezimbili. Okokuqala, i-photodiode yokulawula iqinisekisile izimfanelo. Okwesibili, kulula ukulungisa ubukhali bokukhanya kokufaka. Uma usebenzisa i-photodiode yangaphakathi yomlawuli, sicela uqiniseke ukuthi ugesi wokukhipha we-photodiode ulingana ngokuphelele namandla okufaka.
