Abstract: Provided is a resonant reflective filter including a substrate and a grating layer, wherein the substrate is formed of a material having a lower reflective index than that of a material forming the grating layer Thus, the resonant reflective filter can form a resonant spectrum having good symmetry and a sharp shape. Accordingly, the resonant reflective filter can have improved sensitivity and can be applied to optical systems that require a small linewidth.
