title: Modal analysis for optimization of single-mode waveguide pigtailing and fiber splicing.
abstract: We examine the waveguide dimension and refractive-index difference space for the optimization of single-mode channel waveguide pigtails and optical fiber splices, and we explain these results using modal analysis. We present closed-form equations for the evaluation of the optimal index difference and the allowable variation in its value in any material. We provide a novel way of viewing common waveguide physical parameters and translating them into information that determines the efficacy of a fiber connection.
