An adjustable compound optical microlens apparatus comprises first and second microlenses that are separated from one another along their optical axes. At least one of the microlenses is movable relative to the other. In a preferred embodiment, one microlens is stationary, the other movable. A MEMS controller electrically controls the position of the movable microlens relative to the stationary microlens, or the positions of at least two movable microlenses relative to one another. In accordance with one embodiment of our invention, an array of such microlens apparatuses is also contemplated, especially for applications such optical switches and routers. In accordance with another embodiment of our invention, the apparatus functions as an optical filter or dispersion compensator. Also described is method of compensating for variations in an optical parameter (e.g., effective focal length) of such an apparatus in an array.
