Add-drop optical switches include fixed reflectors, such as fixed mirrors, a nd movable reflectors, such as movable minors, wherein none of the fixed reflectors and none of the movable reflectors are oriented orthogonal to one another on a substrate when the movable reflectors that provide the add-drop functionality are in a radiatio n reflecting position. In preferred embodiments, each of the fixed and movable reflectors is oriented parallel to or at a 70.degree. angle to, the remaining fixed and movable reflectors when the movable reflectors are in the radiation reflecting position. Most preferably, the fixed reflectors and the movable reflectors all are oriented on the substrate in parallel when th e movable reflectors are in the radiation reflecting position. By providing these orientations of fixed and movable reflectors, add-drop optical switches may be fabricated on silic on substrates using wet etching along crystallographic planes. High performance add-drop optical switches thereby may be provided.
