Paper Abstract

Broad band-rejection all fiber filters based on Long Period Fiber Gratings were fabricated by a novel method. Adopting the grating period (Lambda) equals 550 micrometer, and (Lambda) equals 610 micrometer, number of periods N equals 15 and different heating condition, the two kinds of devices are obtained with different band-rejection peak wavelengths at 1310 nm and 1550 nm, respectively. The isolation is more than 25 dB. The bandwidth at the 10 nm isolation point is over 20 nm. The insertion loss is less than 1.2 dB and backward reflection loss is less than -70 dB.
