Abstract
A micromechanical reflection phase grating may be formed of spring-like ribbon reflectors that are secured to a transparent cover positioned over a substrate such as a silicon substrate. The ribbon reflectors are formed independently of the silicon substrate. If a defect occurs in the phase grating and particularly the ribbon reflectors, the top plate assembly can be reworked or discarded without sacrificing the relatively expensive silicon substrate.
