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.

Method of using photonic integrated circuit having redundant light path

A conductive line structure includes: first and second offset sets of long pillars that are substantially coaxial on an intra-set basis; a third set of offset short pillars, the short pillars being: overlapping of long pillars in the first and second sets; and organized into groups of first quantities of the short pillars; each of the groups being overlapping of and electrically coupled between a pair of one of the long pillars in the first set and a one of the long pillars in the second set such that, in each of the groups, each short pillar being overlapping of and electrically coupled between the pair; and each long pillar in each of the first and second sets being overlapped by a second quantity of short pillars in the third set and being electrically coupled to same; and the first quantity being less than the second quantity.
