We numerically demonstrate a tri-layer CMOS SiN-plasmonic BTO racetrack modulator for the O-band. The device exhibits 3 dB insertion loss, 66.43 GHz resonance 3dB-bandwidth and an extinction ratio higher than 28 dB for 0.5Vpp voltage.

We present a polymer-based WFE on a low-loss (0.55dB/cm at 1550nm) platform featuring >19dB improvement in radiated power from the InP-based counterpart. This value exceeds the InP/Polymer transition losses advancing the practicality of hybrid scheme
