This paper compares the scalability and energy consumption of switch fabrics for optical and electronic packet switching. In particular, arrayed-waveguide-grating (AWG)-based switches, semiconductor optical amplifier (SOA) gate arrays, electro-optic phased-array switches, and microresonator-based switches are compared with state-of-the-art electronic switch fabrics. The analysis includes the key contributors to energy consumption and the scaling capabilities of each technology. To provide a fair comparison, the analysis takes into account the optical-to-electronic and electronic-to-optical converters and the multiplexers and demultiplexers needed in electronic packet switches. We show that o..View full abstract
