Application: Method of using photonic integrated circuit having redundant light path (Patent ID: US20240077680A1)
The patent filed by Taiwan Semiconductor Manufacturing Co Ltd describes a method for using an integrated circuit that involves monitoring the current between photodetectors and an electronic circuit to determine abnormalities. If an abnormality is detected, a resonant structure is controlled to optically couple different waveguides connected to different photodetectors. The method includes altering the temperature or electrical field of the resonant structure to achieve this optical coupling.
Additionally, the method involves receiving optical signals through waveguides, converting them to electrical signals using photodetectors, and transferring the signals between waveguides using resonant structures in response to abnormal signals. The patent also covers scenarios where optical signals are split, transferred to different waveguides using various resonant structures, and where the resonant structures are controlled to minimize optical coupling in the case of normal current monitoring. The use of resistors and inductors for transferring optical signals is also mentioned in the claims.
