ABSTRACT:
An optical modulator/optical switch is disclosed. The modulator/switch includes a reflective zone plate defined in a movable zone plate support. The reflective zone plate focuses an optical signal reflected therefrom. In response to a control signal, a controlled voltage source applies a voltage across the movable zone plate support and a layer spaced from the zone plate support. The applied voltage generates an electrostatic force that causes the zone plate support to move towards the other layer. When the zone plate support moves, the reflective zone plate's orientation to an optical signal incident thereon changes. Such a change in orientation alters the path of the optical signal reflected from the reflective zone plate. The reflected optical signal can be directed to different receiving waveguides by changing the amplitude of the applied voltage.
