Abstract
We developed and fabricated an all-fiber add–drop filter by recording a Bragg grating in the waist of an asymmetric mode converter–coupler formed by adiabatic tapering and fusing of two locally dissimilar, single-mode optical fibers. The insertion loss of the device was . A narrow spectral bandwidth and a large add–drop efficiency were also demonstrated. In addition, the filter was polarization independent.
