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.

Abstract: An optical MEMS devices is imaged to a different location at which a seco nd optical MEMS device is located in a manner that effectively combines the til t angles of at least one micro mirror of each of the first and second optical devices . The imaging system may reproduce the angle of reflection of the light from the first micro mirror. This may be achieved using a telecentric system, also known as a 4 f system, as the imaging system. The physical size of the arrangement may be reduced b y 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 mirror.

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 optical filter apparatus for processing an optical signal comprising a spectrum broadening device for spectrally dividing one or more channels of the optical signal into a discrete set of spectral components for each channel, a collector for collecting the spectral components on a discrete number of corresponding light channels, one or more processors for individually processing one or more of the spectral components on the light channels, and a combiner for recombining the spectral components on the light channels.

Abstract: A programmable optical demultiplexer can independently assign every inp ut optical channel in a WDM optical communications signal to depart from any desired output port. The demultiplexer device can also be operated in the reverse direction, and thus achieve programmable optical multiplexer functionality, by acceptin g different wavelengths at each of multiple input ports and efficiently combining the wavelength channels at the multiplexer output port. The programmable multiplexer/demultiplexer device has an optical arrangement for spatially dispersing the optical wavelengths, and tunable micro-mirrors for beam steering each channel independently. Controlling the beam reflection direction determines the connectivity between the input and output ports at the wavelength level.

Abstract: Using an imaging system, an optical MEMS devices is imaged so that in combination with an actual one or more other optical MEMS devices, or images thereof, a single virtual optical MEMS device is formed that has the size of each of the optical MEMS devices combined. The physical 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 mirror. The imaging system may reproduce the angle of reflection of the light from the micro mirror, e.g., using a telecentric system. A prism m ay be employed to align the various optical MEMS devices, or images thereof.

Abstract: The beams between a MEMS device and an input source or an output, e.g., a fiber bundle, are caused to be closer to each other at the MEMS device than at the fiber bundle. This can be achieved in a variety ways. This may be achieved a) when each fiber is associated with a respective micro lens of a micro lens array, by insuring that there is a different distance between the centers of adjacent micro lenses than there is for the centers of their corresponding adjacent fibers, b) when the fibers a re terminated by collimators, the direction of the collimators is adjusted to point the beams in a converging manner and c) by employing an optical system that changes the direction of various ones of the beams may be interposed between a) the fiber bundle and b) the corresponding MEMS device.
