A new type of amplified spontaneous emission (ASE) source in the visible range is proposed and experimentally demonstrated using a novel dye-filled hollow optical fiber (HOF) with a ring core, where optical guiding is provided by silica fiber while the gain is obtained by organic dye to form an organic-inorganic hybrid active device. The pump and signal light intensity distributions in the hybrid structure are theoretically analyzed along with experimental results. ASE near 640 nm with 150 nm bandwidth and peak power level of -52.61 dBm has been achieved.
