“…Optical processing of state-of-the-art spectrally-efficient modulation format signals can potentially offer energy and cost reductions over electronic processing when advantage is taken of their ability both to process very broad optical bandwidths and many signals at the same time [1][2][3]. They usually also offer format flexibility and ultra-fast processing speeds.…”

Abstract-We propose and demonstrate simultaneous phase regeneration of six non-return-to-zero (NRZ) binary phase shift keying (BPSK) signals in a single nonlinear medium. The regenerating system which exhibits binary step-like phase transfer functions uses four-wave mixing (FWM) in degenerate dual-pump vector parametric amplifiers implemented in the same nonlinear optical fiber, followed by polarization filtering. Bit-error-ratio (BER) measurements confirm optical-signal-to-ratio (OSNR) improvement and negligible cross-talk across all the regenerated channels, which were impaired at the regenerator input by broadband phase noise.Index Terms-Four wave mixing, nonlinear optics, phase sensitive amplifiers, multi-channel.

“…A LL optical signal processing has been predicted by some to be an essential part of future optical telecommunications networks given its benefits over electronic signal processing in terms of energy and cost scalability with increasing data rate [1], [2]. With the deployment of phase shift keying (PSK) in optical networks, the development of phase regenerators has become particularly desirable and a number of techniques to achieve it have been proposed.…”

Phase regeneration of an M-ary phase shift keyed signal through coherent addition with its (M − 1)th phase harmonic, despite successfully regenerating phase, exhibits a strongly phase-dependent gain. By applying to this scheme, a small alteration that makes use of both the (M − 1)th and conjugated (M + 1)th phase harmonics, this undesirable gain variation may be reduced. We experimentally characterize both systems for the case of four-level phase quantization in terms of their complex transfer profiles and demonstrate a 6.5dB reduction in gain variation using the altered scheme. To perform measurements of the phase transfer profile of each scheme, we synthesize the systems from an optical comb, proposing and implementing a novel method to measure the relative phase between neighboring spectral lines.Index Terms-Four-wave mixing, phase shift keying, optical signal processing, phase sensitive amplification (PSA), phase regeneration, fibre optic parametric amplifier (FOPA).

“…Especially, data rate in the Graphics Double Data Rate 5 (GDDR5), which is used for Ultra High Definition Television (UHDTV), is expected to be exceed 10 Gbps/pin in the near future. With resolution of 7680 x 4320, UHDTV requires high bandwidth for data transmission [1][2]. High bandwidth of UHDTV can be achieved with thousands of number of I/Os, which can be realized by interposer channel.…”

In this paper, crosstalk included eye diagram of high-speed and wide I/O interposer channels are simulated and analyzed. To analyze the crosstalk effect of various substrate channels, silicon, glass, and organic interposers are simulated and compared under the same physical dimensions. In addition, crosstalk included eye diagrams are accurately estimated in short time using 8 worst case input signals. The estimated eye diagrams are investigated at data rate of 10 Gbps.
