1. A waveguide optical modulator, comprising:
- a) a substrate;
b) a waveguide formed in or on the substrate; and
c) a plurality of conductive membranes which define an array wherein each membrane is effective in a first position to be spaced from the waveguide and located along the waveguide, and in a second position to be closer to or to engage the waveguide so that when in the second position, the optical absorption properties of the waveguide change, the individual conductive membranes being arranged along the length of the waveguide and have a distribution of lengths designed to produce a number of discretely addressable optical output levels when a sequence of the membranes of the array are electronically energized.

Abstract
An optical waveguide modulator for modulating an optical beam is described. The modulator includes a substrate and a waveguide formed in or on the substrate. A plurality of conductive membranes which define an array each being effective in a first position to be spaced from the waveguide and located along the waveguide, and in a second position to be closer to or to engage the waveguide so that when in the second position, the optical absorption properties of the waveguide changes.
