Abstract:
A method of mirror layout inside a multi-level optical switch having a plurality of input terminals and a plurality of output terminals, comprising the steps of:installing a first fixed single-sided reflecting mirror and a second fixed single-sided reflecting mirror such that reflecting surfaces of the first and the second fixed single-sided reflecting mirrors face each other and are parallel to each other, and such that a layout region for accommodating a plurality of double-sided reflecting mirrors is formed between the first and the second reflecting mirror; dividing the input terminals into an odd group and an even group; computing a plurality of optical path cross-points by feeding a plurality of input optical paths from the odd group and the even group using a network exchange algorithm; and installing the double-sided reflecting mirrors at the corresponding optical path cross-points in the layout region of the multi-level optical switch.
