  • Publication number: 20100315647
    Abstract: A Mach-Zehnder MEMS interferometer is achieved using two half plane beam splitters formed at respective edges of a first medium. The first beam splitter is optically coupled to receive an incident beam and operates to split the incident beam into two beams, a first one propagating in the first medium towards the second beam splitter and a second one propagating in a second medium. A moveable mirror in the second medium reflects the second beam back towards the second beam splitter to cause interference of the two beams.

  • Publication number: 20100265382
    Abstract: An optical microscanner achieves wide rotation angles utilizing a curved reflector. The optical microscanner includes a moveable mirror for receiving an incident beam and reflecting the incident beam to produce a reflected beam and a Micro Electro-Mechanical System (MEMS) actuator that causes a linear displacement of the moveable minor. The curved reflector produces an angular rotation of the reflected beam based on the linear displacement of the moveable mirror.

  • Publication number: 20100265512
    Abstract: An optical Micro Electro-Mechanical System (MEMS) device provides an optical path retardation multiplier. The MEMS device includes a moveable corner cube reflector, a fixed minor and a MEMS actuator. The moveable corner cube reflector is optically coupled to receive an incident beam and reflect the incident beam through 180 degrees towards the fixed mirror. The fixed minor is optically coupled to reflect a reflected beam back towards the moveable corner cube reflector along a reverse path of the incident beam. The MEMS actuator is coupled to the moveable corner cube reflector to cause a displacement of the moveable corner cube reflector to extend an optical path length of the reflected beam.

  • Patent number: 6847756
    Abstract: An optical switching matrix, including optical input fibers (12) and optical output fibers (14) oriented substantially perpendicular to each other, moveable mirrors (5, 13) placed at the intersections of the directions defined by the various optical fibers, each mirror (13) being capable of moving in order to reflect a beam coming from an optical input fiber, bound for an optical output fiber, and a set of channels defined between the mirrors, inside which the various beams are propagated before and after having encountered the mirrors. The set of mirrors are made on a first substrate wafer (2) that is covered with a second substrate wafer (20), and the various channels (38) are formed between protruding zones (34) present under the second substrate wafers. The protruding zones include housings (33) inside which the moveable mirrors are able to move.
