摘要： 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 may be employed to align the various optical MEMS devices, or images thereof.

摘要： An optical system may be configured as a receiving or as a transmitting system. As a receiving system, it is configured to receive at least one incident laser beam and project the beam into a spot on an array of actuable elements. The position of the spot is determined by the incident angular direction of the beam. The array is configured to track the position of the spot and at each tracked position of the spot to direct the beam onto an actual element. The actuable element tracks the spot so as to direct the beam onto a fixed path toward an optical receiver. As a transmitting system, it includes an actuable element configured to direct the light output from a laser into a spot on an array of actuable elements. The array is configured to track the position of the spot and at each tracked position of the spot to direct the light into a beam-forming system. The beam-forming system is configured to project the light in a transmitted beam having a variable angular direction. The beam angular direction is determined by the position of the spot on the array.

摘要： 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 which, 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 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.

摘要： Signal losses in an optical cross-connect having steerable switching elements for routing optical signals are substantially reduced by controllably and selectively training the steerable switching elements as a function of measured input and output power of a cross-connected optical signal. More specifically, adjustments to the alignment of one or more steerable switching elements associated with a particular cross-connection are performed in a non-intrusive manner to increase the optical signal power in an optical signal while maintaining an active cross-connection of the optical signal. In one illustrative embodiment, optical monitoring arrangements monitor the optical signal power of optical signals coupled to the cross-connect inputs and outputs. The cross-connect includes a switching fabric comprising a plurality of steerable MEMS mirror elements used as switching elements for controllably and selectively directing the light beams within the cross-connect. By comparing the measured optical signal power with a previously stored value representing the expected optical signal power for that cross-connection, small adjustments can then be made, as appropriate, to optimize the alignment of the mirrors associated with the cross-connection. For example, if the difference between the measured and expected optical signal power exceeds a prescribed threshold, then a dithering process is initiated whereby individual mirrors are “walked through” alternate tilt positions until the measured optical signal power has been optimized, e.g., increased.

摘要： A variable optical delay line using MEMS devices. A reflector on a micro machine linear rack is positioned and spaced from an input source and/or an output to receive and reflect input light waves toward the output. 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.

摘要： A variable attenuator device is disclosed that may be magnetically and latchably controlled such that it does not require a continuous power supply to maintain a particular loss level. The variable attenuator comprises two optical components disposed in spaced apart relation to define a gap between them and a magnetic shutter positioned within the gap. The shutter is movable, due to its magnetic properties, from a first position to at least a second position, where the second position may be within, partially within, or outside of the gap. A mechanism is provided for magnetizing or actuating the shutter to cause it to move from the first position to the at least second position. When the shutter is in the first position, it causes a certain amount of attenuation in the signal being transmitted between the two optical components, and when it moves to the at least second position, a different amount of attenuation is caused, such that movement of the shutter causes a variation in the attenuation. With this attenuator, the variation in attenuation may be achieved via coupling loss while the optical components (e.g., mating fibers), are maintained in a fixed position, thereby avoiding difficulties associated with fiber movement.
