Most optical MEMS telecom components operate by moving a reflective surface. wavelength independent optical switches move metal-coated mirrors which are nearly 100% reflective. These include both digital switches, such as the OMM planar switch, and analog beam-steering crossconnects such as the Lucent "LambdaRouter" Another other class of optical MEMS devices move one or more partially reflective surfaces to create controlled interference effects essentially a dielectric filter with an electrically-actuated layer. Examples range from a single-layer digital data modulator to more complex coupled cavity filters such as used in a spectral dispersion compensator.
