Abstract

We report the fabrication of extremely short linear-cavity distributed Bragg reflector fiber lasers (DBR-FLs). It has a total length of 7 mm, with the nominal cavity of only 0.4 mm. The FL has a linewidth and polarization beat frequency of 220 Hz and 18.9 MHz, respectively. The relaxation oscillation frequency and its relative peak are 120 kHz and -75dB/Hz, respectively. The FL exhibited low-noise characteristics, with an intensity noise of -107 dB/Hz at 1 MHz. We constructed a FL sensor array that has great potentials for large-scale, high sensitivity sensing applications.
