Abstract: Various embodiments of the present application are directed to a narrow band filter with high transmission and an image sensor comprising the narrow band filter. In some embodiments, the filter comprises a first distributed Bragg reflector (DBR), a second DBR, a defect layer between the first and second DBRs, and a plurality of columnar structures. The columnar structures extend through the defect layer and have a refractive index different than a refractive index of the defect layer. The first and second DBRs define a low transmission band, and the defect layer defines a high transmission band dividing the low transmission band. The columnar structures shift the high transmission band towards lower or higher wavelengths depending upon a refractive index of the columnar structures and a fill factor of the columnar structures.
