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： 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 apparatus includes a reconfigurable spatial light modulator, a light source, and a transmission filter. The reconfigurable spatial light modulator is capable of producing spatially varying amplitude and/or phase modulations of an incident light wavefront. The light source is configured to direct an illumination light beam towards the reconfigurable spatial light modulator such that the modulator produces a modulated outgoing light beam there from. The transmission filter is configured to spatially filter a light pattern formed by the outgoing light beam and to selectively transmit light from substantially only one diffractive order of the light pattern.

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： An apparatus includes an all-optical transmission line having, at one wavelength, a pair of relatively orthogonal optical propagating modes whose local group velocities differ along a part of the all-optical transmission line. The all-optical transmission line is formed by a sequence of optically end-connected multi-mode fiber segments. The segments include, at least, 80% of the optical path length of the all-optical transmission line. Each segment is configured such that a differential group delay between the pair varies monotonically there along and changes by, at least, 200 pico-seconds thereon.

摘要： An optical coupler for coupling optical-pump power into a multimode fiber configured to transport an optical space-division-multiplexed (SDM) signal, the coupling being performed in a manner that enables amplification of the SDM signal in the multimode fiber via a stimulated-emission process or a stimulated Raman-scattering process. The optical coupler can be a part of an optical transmitter configured for co-directional pumping, an optical receiver configured for contra-directional pumping, or a relay station disposed within an optical communication link and configured for either type of pumping. The optical coupler can advantageously be used, e.g., to offset the different degrees of attenuation to which the SDM-signal components corresponding to different guided modes of the multimode fiber are subjected to therein.
