| description |
This thesis focuses on investigation of self phase modulation (SPM) and cross phase
modulation (XPM) in semiconductor optical amplifier nonlinear optical loop mirror
(SOA-NOLM) and its application in wavelength conversion. An improved architecture
for realization the nonlinear effect using SOA is presented. The objective of this
research is divided into two major parts: first, the investigation of SPM and XPM in
SOA based NOLM and second, its application in wavelength conversion. In this setup,
the control pump wavelength is 1540 nm and the signal wavelength is 1555 nm. The
simulation setup is based on Sagnac interferometer. The gain level is obtained by setting
the injection current of the SOA to 0.2 A. Three different signal repetition rates are used
in the simulation; 2.5 Gbs-1, 5 Gbs-1 and 10 Gbs-1. At low input power, it is noticed that
the signal encountered very small phase change, irrespective of the gain setting of the
SOA. However, as the power increased the phase curve began to diverge. This implied
that in order to achieve a large phase shift at low input signal power, the gain level at
the SOA must be set to a higher value. In this research, the results obtained are the
optimum operation parameters such as the variable injection current for the SPM and
XPM effects in OptSim environment. This system can be used for future research in
other photonic devices and also application in optical signal processing, optical
switching and wavelength conversion. The research also gives knowledge enhancement
and techniques to develop other photonic devices. |
