Wigner functions in optoelectronics: Wave-packet phase-space Monte Carlo solver for waveguide-ring coupling

摘要

Quantum metrology, computing, and sensing are areas generating great interest in photonic devices. Quantum effects in photonic semiconductor devices are, therefore, an area of increasing interest. For short time scales, transient behaviors, and localized interactions, quantum transport solvers are needed to accurately model such behavior. Here, we employ a novel approach to solving the photon quantum Boltzmann equation utilizing a technique similar to particle Monte Carlo for acquiring the photon Wigner function, demonstrating its effectiveness at modeling quantum effects such as entanglement arising from the coupling of a waveguide to a ring resonator.
