1. A light modulator, comprising:
a mirror having first and second surfaces suspended over a cavity arranged under the first surface;
supports attached to the second surface of the mirror;
support posts suspending the mirror over the cavity by the supports, the support posts and supports being formed from a same layer of material; and
an electrode and an optical stack positioned opposite the first surface across the cavity from the mirror such that activation of the electrode causes the mirror to move towards the electrode, changing dimension and interference properties of the cavity.
