Patent ID: 11899334
Assignee: KOREA ADVANCED INSTITUTE OF SCIENCE AND TECHNOLOGY
Field: Optics (Instruments)
Classification: CPC G | IPC G

Claim 14:
15. A silicon photonics-based optical modulator comprising:
radio frequency (RF) metal electrodes for receiving RF electrical signals from a driving driver located outside of the optical modulator;
phase shifters disposed between the RF metal electrodes for and optically modulating optical signals transmitted along optical waveguides;
a bias metal electrode for receiving a bias voltage through one end thereof from a bias power source located outside of the optical modulator;
a resistor-inductor (RL) connecting one ends of the RF metal electrodes to each other; and
silicon capacitors disposed in front of the RF metal electrodes to perform alternating current (AC) coupling on the RF electrical signals received from the driving driver.
