Intense directional light emission from a deformed square-shaped organic light-emitting micro-ring-cavity was observed. The ring-cavity was a dye-doped organic/inorganic hybrid glass film coated on a square-shaped fiber. From the near-field and far-field emission patterns and their emission spectra, both the chaotic whispering-gallery modes and the four-bounce-reflection modes were identified.
