Switchable-multi-wavelength fiber laser based on dual-core all-solid photonic bandgap fiber

Frontiers of Optoelectronics 2010年第3期3卷 283-288页

作者： Jiaqi ZHAO Zhi WANG Yange LIU Bo LIU Key Laboratory of Opto-Electronic Information and Technology Ministry of Education Institute of Modern Optics Nankai University

In this paper, we propose and demonstrate a switchable multi-wavelength fiber laser based on a dualcore all-solid photonic bandgap fiber(PBGF) comb-like filter. The transmission properties of the dual-core all-solid PBGF are theoretically and experimentally *** the fiber ring laser based on the PBGF is realized and its wavelength-selective mechanisms are studied. By adjusting the polarization controller(PC), the number and location of the laser wavelength can be tunable.

multi-wavelength Narrow Linewidth fiber laser Based on Distributed Feedback fiber lasers

Photonic Sensors 2016年第3期6卷 256-260页

作者： Jingsheng LV Haifeng QI Zhiqiang SONG Jian GUO Jiasheng NI Chang WANG Gangding PENG Shandong Key Laboratory of Optical fiber Sensing Technologies Laser Institute of Shandong Academy of SciencesJinan 250014 China School of Electrical Engineering & Telecommunications The University of New South Wales NSW 2052 Australia

A narrow linewidth laser configuration based on distributed feedback fiber lasers （DFB-FL） with eight wavelengths in the international telecommunication union （ITU） grid is presented and realized. In this laser configuration, eight phase-shifted gratings in series are bidirectionally pumped by two 980-nm laser diodes （LDs）. The final laser output with over 10-mW power for each wavelength can be obtained, and the maximum power difference within eight wavelengths is 1.2 dB. The laser configuration with multiple wavelengths and uniform power outputs can be very useful in large scaled optical fiber hydrophone fields.
