WAFER-LEVEL ALIGNMENT OF OPTICAL ELEMENTS

摘要

Methods are disclosed of fabricating an optical assembly An active optical element is disposed near or on a first surface of a slab of optical material (104) A passive optical element is formed on a second surface of the slab, with the second surface being substantially parallel to the first surface (108) An optical axis of the passive optical element is aligned with an optical path between the passive optical element and an active region of the active optical element using a lithographic alignment process (112).
