MEM mirrors application in optical cross-connects

To create a directable beam transmitter or receiver unit, a MEM mirror with two degrees of freedom is required. Due to the diameter of a collimated beam a relatively large mirror area will be required. A beam diameter of 2 to 3 mm is required for an optical cross connect (OXC) sized at 1,024x1,024. A symmetrical design will also be important to handle brightness theorem considerations.
