Abstract:
An optical switch comprising:a plurality of first optical fibers; a plurality of second optical fibers; a first MEMS array optical coupled with the first optical fibers to receive optical signals from the first optical fibers and to direct the optical signals, the first MEMS array defining a first array incidence angle between a normal direction to the first MEMS array and a direction of the received optical signals; a second MEMS array optical coupled with the first MEMS array to receive the directed optical signals and to re-direct the directed optical signals for insertion into the second optical fibers, the second MEMS array defining a second array incidence angle between a normal direction to second MEMS array and a direction of the re-directed optical signals; wherein the first MEMS array include a plurality of rows of MEMS cells and the MEMS cells in adjacent rows are offset by approximately one half cell.
