Dynamic Behavior in the Angular Distribution of Emission from a Micrometer-Sized Asymmetric Liquid Jet

The dynamic behavior in the angular distribution of emission was measured from an asymmetrically distorted liquid jet which was induced by laterally flowing gas. We observed that the intensity pattern was restricted to around φ∼90°,above 2% of the distortion parameter η. The fine structure of the intensity pattern was also restricted to φ∼90°, which is evidence of the directional emission of MDR (morphology-dependent resonance) lights. As η increases, the intensity profile narrows down to φ∼90°and then broadens at η≥5%. We found that a broad peak shifts continuously with a linear relationship to η, which should be related to the detailed shape of deformation. Broad split peaks were observed when the intensity of emission was substantially enhanced for efficient coupling, which is not expected from the ray-optics model for an ideal elliptical microcavity.
