Abstract
An optoelectronic integrated circuit includes (i) a first back-to-back-junction component (BBJC) and a second BBJC that conform to a first fabrication pattern, where the first BBJC includes a first A-type p-n junction (APNJ) in series with a first B-type p-n junction (BPNJ), where the second BBJC includes a second APNJ in series with a second BPNJ, and (ii) an optical component conforming to a second fabrication pattern that superimposes the first fabrication pattern. The APNJs and BPNJs may be identified based overlapping with separate arms of the optical component. The optical component overlaps the APNJs and BPNJs to provide modulation to optical signals using the modulation voltage from the electrodes. The first APNJ, the first BPNJ, the second APNJ, and the second BPNJ are disposed along respective directions, where metal bridges may be used, to reduce an imbalance in the modulation of the optical signals resulting from a fabrication misalignment.
