title: Effects of curved mirror misalignment in a folded waveguide.
abstract: We have previously discussed the transmission and coupling losses of a Gaussian beam in a folded waveguide structure made of two hollow square waveguides placed symmetrically above a spherical mirror with a nonzero on-axis angle between. Here we investigate the additional loss due to the misalignment of the mirror (axial displacement and/or angular tilt). The theoretical results are in good agreement with experiment and provide alignment tolerances for folded waveguide design.
