Abstract
Known semiconductor wafer process technologies are used to manufacture an optical MUX/DeMUX with very precise dimensional control. The manufacturing process eliminates the need to polish optical surfaces of the MUX/DeMUX, which reduces the overall manufacturing costs and the amount of time that is required to manufacture the MUX/DeMUX.
