Abstract
Embodiments herein describe reverse biasing one or more PIN junctions formed in at least one layer of a PSR. The resulting electric fields in the PIN junctions overlap with the optical path of the optical signal and sweep away photo-generated hole-electron free carriers away. That is, the electric fields in the PIN junctions remove the free carriers from the path of the optical signal and reduces the population of the free carriers, thereby mitigating the negative impact of free-carrier absorption (FCA).
