Abstract

Optical filters with ultranarrow wavelength spacing of 0.068, 0.052, and 0.032 nm, are designed and fabricated on uniform fiber Bragg grating (FBG). Moreover, triple‐, and quadruple‐transmission bands with wavelength spacing of 0.050, 0.046 nm, respectively, are achieved through introducing three and four phase shifts along the fiber Bragg grating. These filters can be applied in the ultranarrow wavelength spacing filtering, photonic generation of microwave signal, multiwavelength distributed feedback Bragg lasing, etc. © 2007 Wiley Periodicals, Inc.

## Abstract Phase sampling and phase shift techniques are introduced in a uniform fiber Bragg grating structure to achieve a multi‐bandpass filter with ultranarrow transmission bandwidth. A pair of dual‐bandpass transmission windows are opened at 1542.32, 1542.36, and 1542.66, 1542.71 nm, respectiv
