Abstract

We report on a tunable optical wavelength deinterleaver based on a microelectromechanical system micromirror array in a modified Gires-Tournois interferometer. Continuous wavelength tuning and switching of the deinterleaver outputs are achieved by vertical micromirror motion of less than 1 μm. Control of the channel spacing, or free spectral range of the device, is also experimentally demonstrated.
