Abstract
The present disclosure describes systems and methods for detecting temperature in an electro-optical circuit (e.g., an electro-optical transceiver). According to an embodiment, an electro-optical circuit includes a photonic integrated circuit and an electronic integrated circuit. The photonic integrated circuit includes an optical component and a first resistor positioned by the optical component. The electronic integrated circuit determines a temperature for the optical component based on a first resistance of the first resistor.
