Abstract
An optical assembly is formed with a silicon substrate having a first surface and a second surface confronting the first surface. A reflective coating is formed over the first surface. Multiple diffraction gratings are formed integrally within the second surface of the silicon substrate. An optical absorber is formed over the second surface between the diffraction gratings.
