Abstract

A widely tunable low stimulated Brillouin scattering (SBS) photonic crystal fiber (PCF) based multi-wavelength Brillouin-erbium fiber laser is presented. The fiber laser structure utilizes a pre-amplified Brillouin pump (BP) technique with 100 m of PCF and a tunable band-pass filter within a Fabry-Perot cavity. A total of 14 Brillouin Stokes lines can be tuned over 29 nm from 1540 nm to 1569 nm. The wide tunability was only limited by the bandwidth of the tunable band-pass filter. A constant channel spacing of 0.079 nm and signal to noise ratio (SNR) of more than 20 dB for each Brillouin Stokes lines were also observed.

摘要

本文介绍了一种基于广泛可调谐低受激布里渊散射（SBS）光子晶体光纤（PCF）的多波长布里渊 - 铒光纤激光器。该光纤激光器结构采用了预放大布里渊泵浦（BP）技术，包含100米的光子晶体光纤以及法布里 - 珀罗腔内的可调带通滤波器。总共14条布里渊斯托克斯线可在1540纳米至1569纳米范围内调谐29纳米。宽调谐性仅受可调带通滤波器带宽的限制。还观察到每条布里渊斯托克斯线的恒定信道间距为0.079纳米，信噪比（SNR）超过20分贝。
