这些结果对研制反射式VOA有重要指导意义。

Abstract

The Wavelength Dependent Loss（WDL） formula for the reflection-type Variable Optical Attenuator（VOA） based on Micro-Electro-Mechanical Systems（MEMS） is deduced by using matrix optics in connection with Gauss beam coupling.Such factors that are related to WDL as the air gap length d1 between the dual fiber pigtail and C-Lens

the lens length d2 and the refractive index and the curvature radius of C-Lens are analyzed in detail and numerical simulations performed respectively.The resulted key factors have major significance to the development of the MEMS-based reflection-type VOA.
