A variable optical attenuator, or VOA, for attenuating an optical signal between two photonic components by changing an alignment of a light beam with an output photonic component in at least two dimensions. A first configuration of the invented VOA has an actuator and two optical fibers. The actuator moves one optical fiber to form a light beam trajectory on the remaining optical fiber, wherein the shape of the trajectory has at least two separate dimensional components. A second configuration of the invented VOA includes a mirror that the actuator moves within at least two degrees of freedom and thereby forms a two-dimensional trajectory of the reflected light beam on a photonic component. A third embodiment includes a mirror, a mirror actuator and a dual fiber collimator having a lens and two optical fibers. The VOA may be partially or wholly integrated on a substrate and/or incorporated as a MEMS-based device.
