    Abstract: In an all optical switch an imaging system is interposed between the micro lens array and the moveable micro mirrors of a MEMS device to which, or from whic h, the light beams are directed. This causes an image of the micro lens array to be formed at the MEMS device, or vice-versa, thus effectively eliminating the distance between the micro lens array and the MEMS device. The imaging system may be a telecentri c system. The size of the arrangement may be reduced by compacting the optical path, e.g., using appropriate conventional mirrors, and/or employing folded arrangements, i.e., arrangements in which there is only one MEMS device stage that does double duty for both input and output through the use of at least one conventional mirro r. The overall system is arranged to account for any inversions introduced.

    Abstract: An opto-isolator incorporating a MEMS device includes an optical signal source and an optical signal detector defining therebeween an optical path for communication of optical signals. A MEMS device having an actuator for controlling a moveable element is disposed between the source and detector for manipulating the optical signals. In one embodiment, the moveable element is a shutter which is operable to selectively allow optical signals to be received by the detector and prevent signals from being detected. In another embodiment, the moveable member is a MEMS tilt mirror for selectively directing optical signals to the detecto r.

    Abstract: A variable optical delay line using MEMS devices. A reflector (16a,16b) on a micro machine linear rack (18) is positioned and spaced from an input source and/or an output to receive and reflect input light waves (12a) toward the output (14a). The distance between the reflector and the input and output is variable and thereby enables selective path delay compensation of the input light wave signals. Other disclosed embodiments utilize pivoting MEMS mirrors and selective adjustment of the mirror pivot angles to provide the selective path delay compensation required in a light wave system.

    Abstract: An optical crossconnect (OXC) fabric including an array of tiltable mirrors, a reflector and a plurality of optical fibers controls the position of the mirrors to optimize the transfer of a signal between an input optical fiber and an output optical fiber by monitoring the optical signal at an optical translation unit in each of the input optical fiber and the output optical fiber. The optical translation units are operable for regenerating the optical signals transmitted through the fibers.
