With the advantages of high speed, small size, and easy integration, silicon photonic resonant ring modulator has gradually become a critical device for emerging integrated optical platforms. Ring modulators are primarily used in communications, computing, artificial intelligence, other fields. In this work, proposed can operate both O- C-bands. The 3 dB electro-optical (EO) bandwidth is 39 GHz 34 at −4 V O-band C-band, respectively. modulation efficiency 0.92 V·cm 0.95 eye diagram an output signal from tested using 100 Gbit/s non-return-to-zero (NRZ) input with 2.5 Vpp C-band. speed reach 140 Gb/s 120 C-band four-level pulse amplitude (PAM-4) formats voltage swing Vpp,
