<p>A photogenic switch includes an array of waveguides 'optical fibers' (20a, 20b, 20c) that are rigidly mounted together and arranged as a matrix (22). One waveguide acts as an input for the switch, and is used to transmit a light beam (44) into free space. The other waveguides then function individually as outputs for the switch. Operationally, a switch connection is made by moving a steering mirror (12) to direct the light beam from the input waveguide to a selected output waveguide. For one embodiment, the mirror is flat. For this embodiment the switch incorporates a collimating lens (16) positioned between the array and the mirror, with the mirror at the telecentric stop of the lens. In another embodiment, the mirror has a concave surface.</p> |
