Abstract
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.
