optical filterThe potential was investigated of using distributed feedback fiber lasers (DFB-FLs) with different apodizations for C-band optical filtering. Design optimizations were carried out, to mainly target ultra-dense wavelength division multiplexing (UDWDM) filtering specifications. Optimization led...

Enhanced side-mode suppression in a distributed-feedback (DFB) structure with gain which is optically pumped to produce lasing action can be achieved when the structure is apodized. Side-mode suppression exceeding 50 dB in a phase-shifted apodized DFB fiber laser is experimentally observed....
