Abstract
A photonic integrated circuit (PIC) device has photonic devices arranged in an array with respect to control and common conductors. Each of the photonic devices has a photonic component (e.g., photodiode, thermo-optic phase shifter, etc.) and a switching diode connected in series with one another between a control connection and a common connection. The photonic component has at least one optical port, which can be coupled to a waveguide in the PIC device. The switching diode is configured to switch between reverse and forward bias in response to the electrical signals. In this way, control circuitry for providing control and monitoring signals to the conductors can be greatly simplified, and the PIC device can be more compact.
