Abstract
A method of using an integrated circuit includes monitoring a current between a first photodetector (PD) and an electronic circuit. The method further includes determining whether the monitored current is abnormal. The method further includes controlling a resonant structure to optically couple a first waveguide connected to the first PD to a second waveguide connected to a second PD, different from the first PD, in response to a determination that the monitored current is abnormal.
