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: 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 ditstance between the reflector and the input and output is variable and thereby ennables 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.

Abstract: Methods and apparatus are described for generating and receiving amplitude and differential-phase encoded signals in which the number of phase states at a given amplitude level is always less than or equal to that at a higher amplitude level and at least two amplitude levels have different numbers of phase states.

Abstract: An optical device for routing a plurality of optical signals between a first port and a second port is disclosed. The optical device includes a mirror array having a plurality of reflective elements. Each optical input signal is directed by a reflective element in a direction designated by a control signal. The optical device further includes a curved mirror for receiving each directed optical signal from the respective reflective element, and for reflecting each directed optical signal to the first or second port.

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: A communication system adapted to use wavelength (frequency) division multiplexing for quantum-key distribution (QKD) and having a transmitter coupled to a receiver via a transmission link. In one embodiment, the receiv er is adapted to (i) phase- shift a local oscillator (LO) signal generated at t he receiver, (ii) combine the LO signal with a quantum-information (QI) signal received via the transmission link from the transmitter to produce interference signals, (iii) measure an intensity difference for these interference signals, and (iv) phase-lock the LO signal to the QI signal bas ed on the measurement result, hi one configuration, the QI signal has a plurali ty of pilot frequency components, each carrying a training signal, and a plurality of QKD frequency components, each carrying quantum key data. Advantageously, the system can maintain a phase lock for the QKD frequency components of the QI and LO signals, while the QKD frequency components of t he QI signal continuously carry quantum key data.
