Dissipative soliton resonances in normal and anomalous dispersion regimes by using a CFBG for dispersion management

We have experimentally demonstrated the generation of DSR in normal and anomalous dispersion regimes by using a chirped fiber Bragg grating (CFBG) for dispersion management. The dispersions of our proposed laser are calculated to be around +5.34 ps2 and -2.66 ps2 with different directions of CFBG. By properly adjusting the polarization state and pump power, we can achieve two kinds of square pulses with different shapes at the fundamental frequency of 3.58 MHz and 3.583 MHz, respectively. The width of square pulse can be tuned from 1.65 ns to 5.43 ns in normal dispersion regime. The width of square pulse can be tuned from 1 ns to 2.7 ns in anomalous dispersion regime.
