Abstract
A liquid core optical fiber (LCOF) composed of hollow fiber and a solution of (-thenoyltrifluoroacetone, , 10-phenanthroline) in dimethyl sulfoxide (DMSO) has been fabricated, in which the concentration of in DMSO is , the core diameter of the LCOF is , and the fiber length is . By the end pumping with a diode-pumped solid-state laser at , a small optical signal at was amplified with a gain of at a pump power of . Based on this experimental result, a liquid core optical fiber amplifier can be realized by the LCOF, which has wide potential applications in many optical devices.
