Linewidth optimization in fiber grating Fabry–Perot laser

Linewidth optimization of a fiber grating Fabry–Perot(FGFP) laser is performed numerically. In addition to the external optical feedback (OFB), the effect of temperature, injection current, cavity volume, gain compression factor, and external cavity parameters [i.e., coupling coefficient (Co) and ex...
