Abstract

A single wavelength ring Brillouin fiber laser (BFL) is demonstrated using a piece of Photonic crystal fiber (PCF) as a gain medium.The BFL has a peak power of more than 0 dBm, a side mode suppression ratio of more than 26 dB and a BP threshold power of approximately 9.4 dBm with 100‐m long PCF. The threshold of the BFL increases with the use of shorter PCFs. The Brillouin gain coefficient was calculated to be 3.2 × 10^−11^ m/W using the measured BP threshold power. A figure of merit of the proposed BFL is calculated to be nearly 76 times larger than the best silica‐based configurations reported to date. The induced time delay is approximately 0.056 (ns/mW/m), which is suitable for slow light‐based applications. © 2011 Wiley Periodicals, Inc.
