Theory of optical second-harmonic generation in crystal-cored fibers based on phase matching of Čerenkov-type radiation

Abstract

A general formulation of optical second-harmonic generation in crystal-cored fibers is described. Although pump depletion of the fundamental wave and anisotropy of the core crystal are ignored, the theory and its numerical results provide a practical means of designing frequency doublers that make use of nonlinear-optical fibers. Comparison with previous results is also provided.
