  • Publication number: 20220221743
    Abstract: Techniques for termination for microring modulators are disclosed. In the illustrative embodiment, a microring modulator on a photonic integrated circuit (PIC) die is modulated by radiofrequency (RF) signals connected to electrodes across the microring modulator. A resistor is connected to each of the electrodes. The resistors both provide termination for the RF signals, preventing or reducing reflections, as well as forming part of a bias tee, allowing for a DC bias voltage to be applied across the electrodes.
