Abstract

A fiber optic 1xN switch (200) is constructed using a MEMS mirror (204) to accomplish switching. The fiber ends (a, b, c) are magnified onto the mirror (204) to reduce optical power concentration at the mirror (204). The switch has low sensitivity to polarization, due to near normal reflectance at the mirror (204). In addition, the enlarged beam diameter at the mirror surface and the correspondingly enlarged mirror also relaxes manufacturing tolerances to provide a more practical design.
