The orientation and positioning of pn junctions play a crucial role in the performance of optoelectronic modulators, with vertical pn junctions showing promise in improving energy efficiency. New designs such as double vertical junctions offer increased interaction length and energy efficiency improvements. Comprehensive numerical comparisons demonstrate the potential of these new designs in enhancing power performance characteristics.
One of the most critical elements in a data center transceiver is the optoelectronic modulator. In a silicon-based optoelectronic modulator, the ultimate performance depends on the orientation and positioning of its pn junction(s). In comparison to a conventional, lateral pn junction, a vertical pn junction improves energy efficiency by having a stronger overlap with the resonant optical signal. Adding to this design philosophy, we present two new designs of vertical junction modulators: (i) a double vertical junction, which doubles the interaction length, and (ii) a staggered double vertical junction, which further increases the interaction length by adding a lateral component to the double junction design. In this work, we provide a comprehensive numerical comparison of microring/disk modulators between the conventional, lateral pn junction and our vertical pn junction designs. We demonstrate how our new double vertical junction configurations offer the most promising power performance characteristics, with an energy-efficiency improvement by over a factor of 4. Our work may pave the way for new, energy-efficient silicon modulators in next-generation information processing and communications.
