Abstract

The opto-electronic assembly receiving optical signals. Two detectors, each with an optically active area, convert optical signals into electrical signals. Two of the detectors are arranged on each other, and the optically active area of one detector is shielded. The opto-electronic assembly receives the optical signals and detects interference signals reliably. The assembly requires little space within an opto-electronic structure and can be produced simply and cost-effectively.
