Abstract

We present the design and fabrication of a broadband all-fiber wavelength-division multiplexing (WDM) filter based on the long-period grating (LPG) technology. By utilizing the improved LPGs, i.e. the LPG with step-changed index modulation, an LPG with a 3-dB flat-bottom stop-band was designed with transfer matrix method. The fabrications of the designed LPG and the broadband WDM filter are also realized by using the point-by-point grating writing technique in the experiments.
