I-1 MER ibhekisela ku-Intrinsic Modulator Extinction Ratio. Isilinganiso sokuqothulwa esifinyelelwe ngokuvamile siyisilinganiso sokushabalala semodeli esicaciswe kudatha yemoduli.
2VumelaVπ bonisa i-bias voltage ku-180◦ futhiVP isho amandla kagesi okuchema alungiselelwe kakhulu kumaphuzu angama-Quad.
3Sicela uqaphele ukuthi amandla okukhanya okufakwayo awabhekiseli emandleni okubona endaweni ekhethiwe yokuchema. Kungamandla amakhulu okubona imoduli engawathumela kusilawuli lapho i-voltage echema isukela−Vπ kuye +Vπ .

1 I-Polar incike esignali yesistimu ye-RF. Uma ingekho isignali ye-RF ohlelweni, i-polar kufanele ibe iphozithivu. Uma isignali ye-RF ine-amplitude enkulu kuneleveli ethile, i-polar izoshintsha isuke ekubeni iphozithivu iye kwenegethivu. Ngalesi sikhathi, i-Null point ne-Peak point zizoshintshana. Iphoyinti le-Q+ kanye nephoyinti le-Q zizoshintshana futhi. Ukushintshwa kwe-Polar kuvumela umsebenzisi ukuthi ashintshe
polar ngqo ngaphandle kokushintsha izindawo zokusebenza.

1 Kuphela ukukhetha okuzokhethwa phakathi kokusebenzisa i-photodiode yesilawuli noma ukusebenzisa i-modulator photodiode. Kunconywa ukusebenzisa i-photodiode yesilawuli ekuhlolweni kweLab ngezizathu ezimbili. Okokuqala, i-photodiode yesilawuli inezimfanelo eziqinisekisiwe. Okwesibili, kulula ukulungisa amandla okukhanya okokufaka. Uma usebenzisa i-photodiode yangaphakathi yemoduli, sicela wenze isiqiniseko sokuthi ukuphuma kwe-photodiode kuhambisana ngokuqinile namandla okokufaka.
