Abstract: PROBLEM TO BE SOLVED: To provide a full optical switching which does not increase the number of micromirrors used to implement a switching function and uses an MEMS device. SOLUTION: Using an imaging system, the optical MEMS device 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.

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: In an all optical switch an imaging system is optically coupled to the moveable micro mirrors of a MEMS device so as to produce an image of the MEMS device at the end of the imaging system which is not coupled to the MEMS device. The image is substantially in a plane with either input or output of the optical switch. The imaging system may be a telecentric 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 mirror. The overall system is arranged to account for any inversions introduced.
