    "abstract": "Motivated by the recent observation of periodic filter characteristics of an\noval-shaped micro-cavity, we study the possible interference of multiple beams\nin the far field of a laser-illuminated quadrupolar glass fiber. From numerical\nray-tracing simulations of the experimental situation we obtain the\ninterference-relevant length-difference spectrum and compare it with data\nextracted from the experimental filter results. Our analysis reveals that\ndifferent polygonal cavity modes being refractively output-coupled in the\nhigh-curvature region of the fiber contribute to the observed far-field\ninterference.",
