Abstract
In this paper a silicon-on-insulator nanorib waveguide with
reverse-biased p-i-n-junction is used to experimentally demonstrate
phase-sensitive amplification based on four-wave mixing for the
realization of an in-line four-level phase-regenerator. Phase regeneration
of a 14-GBd quadrature phase-shift keying signal is demonstrated for the
first time employing a silicon waveguide as phase sensitive amplifier. The
regenerator is placed in a 1040-km dispersion-managed link and it is shown
that phase noise accumulation in the transmission link can be reduced by
the use of the in-line silicon-based phase-regeneration.
