Simulation results of the proposed structure. a The phase of Tx, Ty and there difference when Wx = 100 nm. b Transmittance T, Tx and Ty, and the phase difference of the two transmission lights. c Tx and Ty curves when Wx changes. The small image is the detailed diagram near 1550 nm. It shows the variation trends of Tx, Ty, total transmittance T, and phase difference at the communication wavelength
