Title: | Ultra-short distributed Bragg reflector fiber laser for sensing applications | Authors: | Zhang, Y Guan, BO Tam, HY |
Issue Date: | 8-Jun-2009 | Source: | Optics express, 8 June 2009, v. 17, no. 12, p. 10050-10055 | Abstract: | We present an ultra-short distributed Bragg reflector fiber laser written in Er/Yb co-doped fiber. The entire laser is only 8.4 mm in length. The lasing threshold is less than 1 mW. The optical signal-to-noise ratio of the laser output is better than 70 dB. The laser emits two orthogonal polarization modes and generates a beat signal with signal-to-noise ratio of ~70 dB and 3-dB linewidth of ~3 kHz. The laser has longitude mode spacing comparable to the grating bandwidth. This obviates the possibility of mode hopping when the laser is subjected to any external perturbations. | Keywords: | Acoustic intensity Bragg cells Distributed Bragg reflectors Fiber lasers Optical signal processing Reflection Signal to noise ratio |
