A family of optical switches. Each switch (400) includes a holder block (402) to hold optical fibers (410, 412) and ferrules (414) in alignment with a micromirror array (406). The holder block 402 has a reflective bottom surface (404). The bottom surface (404) functions as a retro-reflector when the optical switch (400) is assembled. The micromirror array (406) has a substrate on which rows of micromirrors have been fabricated. The ferrules (414) are held at an angle relative to the micromirror array (406). This angle allows the light emitted from the input fiber (410) to traverse the array of micromirrors (406) to the output fiber (412). Light from the input fiber (410) is reflected between a series of mirrors (408) and the retro-reflective surface (404) until reaching the output fiber (412). The rotation of the mirrors determines the path of light across the mirror array (406) and which output fiber (412) the light reaches.
