Efficient photon pair sources based on Silicon-on-Insulatormicroresonators

摘要

We present a general quantum-mechanical formalism to describe photon-pair generation via four-wave mixing in a Silicon-on-Insulator (SOI) microresonator. We also provide design principles for efficient photon-pair generation in an SOI microresonator through numerical simulations. Ring-cavity designs are shown to have a much wider dispersion-compensate frequency range than straight-cavity designs. Such on-chip quantum devices are highly promising for future integrated quantum information processing.
