Abstract:
The field of optical communication has gained rapid development throughout
the past years. With the exponentially increasing demand for the internet, the
existing transmission bandwidth of fiber optic communication has become insufficient
to meet up with end-user requirements. Hence, it is necessary to increase the
data rate while enhancing the quality of optical communication systems. Due to
the unavailability of high-speed electronics, typical intensity modulation is hard
to improve further. One future proof option is to use phase modulated schemes
or a combination of phase and amplitude modulation schemes. In this scenario,
simultaneous amplitude and phase regeneration schemes are implemented thus
making phase synchronization a major concern during the regeneration process.
This research is intended to extract the carrier signal phase using the principle of
four wave mixing (FWM) and to implement a successful optical carrier recovery
scheme. The noise influences from the signal laser for the recovered carrier have
been investigated both theoretically and experimentally. Also, the dispersion
effects have been analyzed experimentally
