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.
