     generic model and thorough investigation are proposed for a novel 1×2 polymer electro-optic (eo) switch based on one-group 2n+1 vertical-turning serial-coupled microrings. for realizing boxlike flat spectrum as well as low crosstalk and insertion loss, resonance order and coupling gaps are optimized. the mrr switches with n≥1 reveal favorable boxlike spectrum as when compared with the simple device with only one microring ( n=0 ). for obtaining <−30 db  crosstalk under through-state, the dependency of switching voltage on n is determined as 7.19× exp (−n/0.72)+1.72( v ) . under the operation voltages of 0 v (drop state) and the predicted switching voltages (through state), the device performances are analyzed, and 1≤n≤10 is required for dropping the insertion loss (drop state) below 10 db. the crosstalk of the ten devices ( n=1−10 ) are <−19.5 db  under drop state and <−28.7 db  under through state, and the insertion losses of the devices ( n=1−10 ) are <9.715 db  under drop state and <1.573 db  under through state. the device also has ultra-compact footprint size of only 0.33–1.06 mm, which is only 1/10–1/3 of those of our previously reported polymer eo switches based on directional coupler or mach–zehnder interferometer structures. therefore, the proposed device is capable of highly integration onto optical networks-on-chip.
