Optical resonant filters represent an important alternative to achieve optical notch filtering. Enhancing the filtering properties by new designs for these filters is an essential aspect because they can be a key component in important systems, such as optical communications, bio-photonics applications, and optical sensors. The proposed designs depend on a multilayer waveguide that can function as a confining medium and an antireflection coating as well, which are not achieved simultaneously by a single-layer waveguide. Zeroing the Fresnel reflection, which is the background reflection in the reflection spectra of the optical resonant filter, is highly desirable for better filtering properties.
