| Zusammenfassung: | An optical matrix switch station (
1
) is shown mounting a plurality of optical switch units (
15, 17
), each of which includes a mirror (
29
), moveable in two axes, for purpose of switching optical beams from one optical fiber to another. A mirror assembly (
41
) includes a single body of silicon comprising a frame portion (
43
), gimbals (
45
), mirror portion (
47
), and related hinges (
55
). Magnets (
53, 54
) and air coils (
89
) are utilized to position the central mirror surface (
29
) to a selected orientation. The moveable mirror and associated magnets along with control LED's (
71
) are hermetically packaged in a header (
81
) and mounted with the air coils on mounting bracket (
85
) to form a micromirror assembly package (
99
) mounted in each optical switch unit. |
