“…In the first instance, space-division multiplexing is used to allow each of the channels to be processed in separate but identical regenerators, see Fig.1 (a) [14][15][23][24][25][26]. After regeneration, the channels are then recombined together through a wavelength multiplexer into a single fiber for further transmission.…”

“…After regeneration, the channels are then recombined together through a wavelength multiplexer into a single fiber for further transmission. This implementation has been demonstrated exploiting several nonlinear systems, including Mach-Zehnder modulators [23], saturable absorbers [14][15] and fiber-based nonlinear optical loop mirrors [24][25][26]. In more detail, O. Leclerc et al reported in [23] the very first demonstration in a transmission loop of simultaneous optical regeneration of four RZ OOK 200 GHz spaced 40Gbit/s channels, allocating a soliton compression regenerator [26] to each channel followed by a common InP Mach-Zehnder modulator to achieve full 3R regeneration.…”

Using the same approach, K. Cvecek et al have more recently demonstrated a phase preserving amplitude regenerator for two 10Gbit/s RZ differential phase shift keying (DPSK) signals using a nonlinear amplifying loop mirror with a penalty less than 0.2dB in the receiver input power between single-and multi-channel operation [26].…”

Abstract-Multi-wavelength all-optical regeneration has the potential to substantially increase both the capacity and scalability of future optical networks. In this paper we review recent promising developments in this area. First we recall the basic principles of multi-channel regeneration of high bit rate signals in optical communication systems before discussing the current technological approaches. We then describe in detail two fiber-based multi-channel 2R regeneration techniques for RZ-OOK based on (a) dispersion managed systems and (b) direction and polarization multiplexing. We present results illustrating the levels of performance so far achieved and discuss various practical issues and prospects for further performance enhancement.Index Terms-Nonlinear optical, devices; Kerr effect; signal regeneration; nonlinear optical signal processing; ultrafast processes in fibers.

“…To improve fabrication yields, they are typically constructed from y-junction couplers so that there is usually only single input (E in1 ) and output ports (E out1 )-with the secondary input and output ports being unguided waste ports. MZMs are also fabricated in semiconductor materials such as GaAs [143], InP [291,292], Si [293,294], and optical polymers [295]. For ultra-fast applications, nonlinear interferometric switches constructed from fibers, semiconductor optical amplifiers, and other nonlinear materials [296][297][298][299][300][301][302], have demonstrated 100 GHz class all-optical logic, wavelength conversion, and clock-recovery.…”

Free-space laser communication systems have the potential to provide flexible, high-speed connectivity suitable for long-haul intersatellite and deep-space links. For these applications, power-efficient transmitter and receiver designs are essential for cost-effective implementation. State-of-the-art designs can leverage many of the recent advances in optical communication technologies that have led to global wideband fiber-optic networks with multiple Tbit/s capacities. While spectral efficiency has long been a key design parameter in the telecommunications industry, the many THz of excess channel bandwidth in the optical regime can be used to improve receiver sensitivities where photon efficiency is a design driver. Furthermore, the combination of excess bandwidth and average-power-limited optical transmitters has led to a new paradigm in transmitter and receiver design that can extend optimized performance of a single receiver to accommodate multiple data rates. This paper discusses state-of-the-art optical transmitter and receiver designs that are particularly well suited for average-power-limited photon-starved links where channel bandwidth is readily available. For comparison, relatively simple direct-detection systems used in short terrestrial or fiber optic links are discussed, but emphasis is placed on mature high-performance photon-efficient systems and commercially available technologies suitable for operation in space. The fundamental characteristics of optical sources, modulators, amplifiers, detectors, and associated noise sources are reviewed along with some of the unique properties that distinguish laser communication systems and components from their RF counterparts. Also addressed is the interplay between modulation format, transmitter waveform, and receiver design, as well as practical tradeoffs and implementation considerations that arise from using various technologies.

“…Promising components for all-optical signal regeneration include interferometric wavelength converters, in which semiconductor optical amplifiers (SOAs) are used as optical phase shifters [1]. The noise redistribution capabilities of these wavelength converters, which have been demonstrated experimentally [2], [3], can be described through the transfer function, which should exhibit a nonlinear thresholding characteristic. With increasing data rates of 40 and 160 Gb/s, the devices are influenced by pattern effects, which will decrease the regeneration performance.…”

Abstract-An efficient method is presented for the estimation of the bit-error rate (BER) of a system employing all-optical regenerators influenced by pattern effects. We theoretically study noise accumulation and noise redistribution in long distance transmission systems employing a delayed interference signal wavelength converter for all-optical regeneration. The BER is studied for return-to-zero signals at bit rates of 2.5 Gb/s (no patterning) up to 40 Gb/s (strong patterning). The calculation of the BER is based on pattern dependent transfer functions, which may be obtained numerically or measured.
