MEMS Mirror Array for a Wavelength Selective 1xK Switch
01 January 2003
We present a new MEMS mirror device that fulfills the requirements needed for its use in a wavelength selective switch. The MEMS device consists of a 1D array of individually controllable tilt micromirrors with almost 100% filling factor. Each mirror in the array is used to manipulate an individual wavelength channel, attenuating or redirecting it into a different output. The mirrors are electrostatically rotated around a fixed pivot and they use a novel concept of angle amplification to increase their out-of-plane angular rotation. A detailed analysis of their mechanical and optical response is presented.
