摘要： An example transmitter includes an encoder, a plurality of modulators and a spatial multiplexer. The encoder is configured to encode one or more input bit streams into a plurality of coded bit streams which are provided as output. Each modulator is configured to receive and modulate a respective one of the plurality of coded bit streams and to provide a modulated output signal. The spatial multiplexer is configured to spatially multiplex the plurality of modulated output signals for insertion on a spatially multiplexing waveguide. A modulated output signal(s) may be inserted onto a mode of a multi-mode fiber or onto a core of a multi-core fiber. In one embodiment, a subset of the plurality of spatially multiplexed modulated output signals which correspond to the one or more input bit streams must be simultaneously and spatially selectively detected in order to recover a first input bit stream.

摘要： An example method includes modulating an optical signal using a Phase Shift Keying (PSK) signal constellation, wherein signal points of the PSK signal constellation are located on at least two rings. The first ring has a first radius r1 and a second ring has a second radius r2, wherein the first radius and second radius differ, and wherein the signal points are not located on a regular n-dimension lattice, where n is an integer. The regular n-dimension lattice is formed from a minimum number of lines parallel to an axis for each of the n-dimensions that connect ones of the signal points of the PSK signal constellation on either side of an origin of the axis. The second radius may be greater than the first radius, with the second radius a non-integer multiple of the first ring radius.

摘要： A method and apparatus for variable duty cycle generation of optical RZ data signals uses a single, NRZ-driven phase modulator followed by a optical delay-line interferometer. If desired, a differential encoder precodes an NRZ data signal before being applied to the data input of a phase modulator arranged to modulate the light emerging from a continuously operating laser. The output of the modulator is then applied to an optical delay interferometer, such that the optical signal is split into first and second optical signals, each of which is applied to a respective one of the two interferometer arms. The interferometer is arranged such that the signal in one of the arms is controllably delayed with respect to the other (a) by a fine delay (on the other of the optical wavelength) to produce destructive interference in the absence of phase modulation by said phase modulator, and (b) by a coarse delay (on the order of a bit period), to produce RZ pulses having the desired duty cycle. The optical signals in each of the arms are then recombined to form the interferometer output, which is the desired optical RZ data signal.

摘要： Method and apparatus for creating a clone relationship between two or more optical-frequency comb sources (OFCSs). In one embodiment, the invention is an apparatus having (i) first and second OFCSs, each adapted to generate a respective frequency comb, and (ii) means for locking the phases of two comb lines of the first OFCS and the phases of the respective two comb lines of the second OFCS to create a full or partial clone relationship between these two OFCSs. In one system configuration, the locking of the phases of the first and second OFCSs is achieved by locking the phases of two selected comb lines generated by each of these OFCSs to the phases of the respective comb lines generated by the same (third, reference) OFCS. In an alternative system configuration, the locking of the phases of the first and second OFCSs is achieved by locking the phases of two selected comb lines generated by the first OFCS to the phases of the respective comb lines generated by the third OFCS, and locking the phases of two selected comb lines generated by the second OFCS to the phases of the respective comb lines generated by the first OFCS.

摘要： A linear optical sampling apparatus, temporally samples a modulated optical signal using the amplitude of the interference of its electric field with the electric field of a laser pulse. The apparatus includes a 90° optical hybrid that combines the optical signal and laser pulse in order to generate two quadratures interference samples SA and SB. A processor compensates for optical and electrical signal handling imperfections in the hybrid, balanced detectors, and A/D converters used in the optical sampling apparatus. The processor numerically scales the two quadratures interference samples SA and SB over a large collection of samples by imposing that the average = =0 and = and then minimizes 2 /( + ) =cos(φB−φA)). This is done by adjusting the phase between the two quadratures (ideally either −π/2 or +π/2) so that cos(φB−φA)) is zero. The processor then generates a demodulated sample signal using the quadratures interference samples SA and SB. According to one feature, the hybrid sets the relative phase between two quadratures of their interferometric component so that the phase sensitivity inherent to linear optics is removed. A variety of hybrid arrangements is disclosed that can be implemented using integrated waveguide technology. The apparatus enables sampling of picosecond pulses up to 640 Gb/s with high sensitivity and temporal resolution.

摘要： An improved multi-channel optical equalizer method and apparatus for intersymbol interference mitigation compensates many wavelength channels simultaneously and requires few adjustable parameters. The equalizer unit has only two control signals, one to control signal magnitude and one to control signal phase, yet it can still compensate many wavelength channels simultaneously. The equalizer includes a coupler with a controllable coupling ratio for splitting the light into two portions and a controllable interferometer means having two arms, one arm having an additional delay which is equal to an integer multiple of 1/&Dgr;f, where &Dgr;f is the channel spacing of the multiwavelength system. The controllable interferometer unit also has a controllable delay in a first or second arm for adjusting the relative phase of the light passing therethrough. A coupler combines the two signal portions from the first and second arms to form the equalized output signal.
