“…By placing the phase shift asymmetrically with respect to the grating center, as shown in Fig. 1(c), larger output power is obtained from the shorter end [10], [16]. In this asymmetric design, the maximum output power from the desired end is obtained for a particular phase-shift position and coupling coefficient value .…”

Abstract-The standard distributed feedback (DFB) laser optimization method is critically investigated and a new design approach based on the effective cavity length is presented. By applying this method in an erbium-ytterbium co-doped fiber, the pump-to-signal conversion ratio is increased by 40% for the same total device length and pumping conditions. The laser with the proposed design is produced and the theoretical results are verified by the experimental work.

Four distributed feedback fiber lasers with dual-wavelength operations were studied experimentally in detail. The laser characteristics of these distributed feedback fiber lasers (DFB-FLs) were investigated. The operation conditions for the dual-wavelength output are analyzed and presented. Through this study, the guidance of the design and fabrication of some dual-wavelength distributed feedback fiber lasers are provided.

“…Several types of single polarization DFB fiber lasers have been demonstrated [12,13,14]. For example, single polarization outputs were obtained by employing the slight polarization-dependent phase-shift [12] caused by mechanical deformation [13] or the difference between the grating strengths of the two orthogonal modes of the fiber [14].…”

“…For example, single polarization outputs were obtained by employing the slight polarization-dependent phase-shift [12] caused by mechanical deformation [13] or the difference between the grating strengths of the two orthogonal modes of the fiber [14]. However, these DFB lasers were fabricated by using non-polarization-maintaining phosphosilicate fibers, which are not widely used in conventional silica-based fiber technology.…”

Abstract:We describe a polarization-maintaining (PM) λ/4-shifted DFB Er-doped fiber laser (EDFL), in which optical pulsation effects caused by Er 3+ ion-pairs were successfully removed by co-doping erbium fiber with 12 wt% aluminum. Stable CW operation was realized at a pump power of 100 mW. The laser exhibited single longitudinalmode oscillation with a single polarization. The output power, linewidth of the longitudinal mode, and RIN at the relaxation oscillation frequency were 0.5 mW, 82 kHz, and −79 dB/Hz at a pump power of 100 mW, respectively. Stable operation was also obtained at a pump power of 140 mW, where the above values were improved to 0.8 mW, 43 kHz, and −92 dB/Hz, respectively.
