Silicon Photonics for Signal Processing of Tbit/s Serial Data Signals

Regeneration of Phase Unlocked Serial Multiplexed DPSK Signals in a Single Phase Sensitive Amplifier

“…However, to offer energy-efficiency, the regenerator must be compatible with multiplexing techniques, such as serial multiplexing based on increasing the symbol rate by interleaving low speed channels in the time domain, or the parallel multiplexing (WDM) scheme based on increasing the number of wavelength channels. In particular, the serial multi-channel approach with fewer wavelength channels, has the potential to reduce the cost per bit due to the reduced number of components, and the power consumption [3]. Furthermore, it has been shown that a WDM regenerator can be implemented using a single serial signal regenerator through optical Fourier transformations, which can be achieved by intermediately converting the parallel channels to a single serial channel, and then applying serial channel regeneration, followed by serial-to-parallel conversion.…”

Ultra-high-speed All-channel Serial-to-parallel Conversion based on Complete Optical Fourier Transformation

“…Due to the rapid traffic growth in optical communication networks, intensive efforts have been made to develop new technologies for the future high capacity energy-efficient communication systems [1]. Presently, optical serial-toparallel conversion of a high-speed optical signal to several low-speed channels at different wavelengths, has received much attention.…”

Multichannel nonlinear distortion compensation using optical phase conjugation in a silicon nanowire

“…These properties make them very attractive for all-optical signal processing. Ultra-high speed [16] and complex modulation format [17] signals have been successfully processed using silicon nanowires, highlighting their great potential. Furthermore, the use of silicon nanowires as an optical phase conjugator has been demonstrated [18].…”
