Abstract
An optical element such as an interference filter will have adjacent layers of different indexes of refraction but formed of the same optical material. An optical element such as a diffraction grating or beam-splitter will have adjacent sections of different indexes of refraction in the same optical material layer. An optical element such as a waveguide will have a core layer of a higher index of refraction partially or completely surrounded by a cladding layer of a lower index of refraction formed of the same optical material.
