Abstract

Converting light to a controllable frequency is well-known in traditional non-linear optics [1]. Driven by device miniaturization in modern nanophotonics, light confined in a cavity or waveguide is frequency converted by pump light [2-5]. Literature has it that the physics of nanophotonic frequency conversion differs from traditional non-linear optics, regarding the rate of phase change (no or yes, respectively) and output spectrum (peaked or continuum, respectively) [2]. Here, we will unify these disparate views.
