摘要：
The use of microelectromechanical systems (MEMS) in optical networks was presented. This system uses the wave aspect of light-interference and diffraction. MEMS uses the Stanford approach in which an array of ribbons suspended one wavelength (λ) above a silicon substrate, it has several advantages over other MEMS- it requires very small movements, provides high resolution frequency, fast response time and is reliable. Its problem of wavelength-dependent loss (WDL) was removed by creating a granting structure perfectly symmetrical in two directions. The achromatic aspect is also included in the design.
