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.
