【Abstract】 This paper studied and manufactured the filter of fiber biconical taper. The relationship between the filter performance and total phase difference of couple-mode was presented. The influence of the taper symmetry on filter peak transmission power was discussed. The spectral chracteristics of tapers with different structures were numerically calculated in order to prove analytic results and were compared with experimental results.更多还原
