“…difference frequency generation. The application of cascaded quadratic nonlinear processes offers a number of potential advantages, such as broadband operation, low-latency, no intrinsic frequency chirp and SBS resilience [93][94][95][96][97][98][99][100]. However, such devices are ultimately limited by power transfer to the third harmonic wavelength, infrared absorption and subsequent temperature instability.…”

Summary:In this Chapter we review the need, general principles and approaches used to regenerate phase encoded signals of differing levels of coding complexity. We will describe the key underpinning technology and present the current state-of-the-art, incorporating an appropriate historic perspective throughout. The chapter finishes with a discussion of emerging research trends and broader future perspectives.

“…Optical regeneration could extend the transmission reach of ultra-high-speed serial data, and it is therefore an important but also challenging functionality. So far, reports include amplituderegeneration of 640 Gbit/s data in PPLN 19 (with wavelength conversion) and of 160 Gbit/s data in HNLF 20 .…”

“…All-optical regenerators have the capability of signal processing at ultra-high speeds and potentially lower power consumption. The highest data rate achieved for single channel all-optical regeneration is 640-Gbit/s in a periodically poled lithium niobate waveguide (PPLN) [2]. As most transmission today is based on multi-channels systems, it would be beneficial if such a high speed optical regenerator could deal with multi-channel signals, but this has so far proven difficult, because of detrimental inter-channel cross-talk due to effects such as XPM, cross gain modulation (XGM) and four-wave mixing (FWM).…”

Simultaneous regeneration of four high-speed (160 Gbit/s) wavelength-division multiplexed (WDM) and polarization-division multiplexed (PDM) signals in a single highly nonlinear fiber (HNLF) is demonstrated. The regeneration operation is based on four-wave mixing in HNLF, where the degraded data signals are applied as the pump. As a result, the noise on both '0' and '1' levels can be suppressed simultaneously in our scheme. The stimulated Brillouin scattering (SBS) from the continuous wave (CW) is suppressed by cross-phase modulation (XPM) from the data pump, relieving the requirement of external phase modulation of the CW light. Mitigation of the inter-channel nonlinearities is achieved mainly through an inter-channel 0.5 bit slot time delay. Bidirectional propagation is also applied to relieve the inter-channel four-wave mixing. The multi-channel regeneration performance is validated by bit-error rate (BER) measurements. The receiver powers at the BER of 10 −9 are improved by 1.9 dB, 1.8 dB, 1.6 dB and 1.5 dB for the four data channels, respectively. ©2014 Optical Society of America
