I-1 MER ibhekisa kwi-intrinsic Modulator Extinction Ratio. I-extinction ratio efunyenweyo idla ngokuba yi-extinction ratio ye-modulator echazwe kwi-datasheet ye-modulator.
2VumelaVπ bonisa i-bias voltage kwi-180◦ kwayeVP ibonisa i-voltage ye-bias engcono kakhulu kwiindawo ze-Quad.
3Nceda uqaphele ukuba amandla okukhanya angenayo akabhekiseli kumandla okukhanya kwindawo ekhethiweyo ye-bias. Ngamandla okukhanya aphezulu anokuthi i-modulator iwathumele kumlawuli xa i-bias voltage isuka kwi−Vπ ukuya ku-+Vπ .

1 I-Polar ixhomekeke kwisignali ye-RF yenkqubo. Xa kungekho signali ye-RF kwinkqubo, i-polar kufuneka ibe ntle. Xa isignali ye-RF inomlinganiselo omkhulu kunomgangatho othile, i-polar iya kutshintsha ukusuka kwi-positive ukuya kwi-negative. Ngeli xesha, i-Null point kunye ne-Peak point ziya kutshintshana. I-Q+ point kunye ne-Q- point ziya kutshintshana. I-Polar switch ivumela umsebenzisi ukuba atshintshe i-
i-polar ngqo ngaphandle kokutshintsha iindawo zokusebenza.
