Abstract
This Study has presented optical interference filters transmission performance under
thermal temperature effects. Different materials are deeply studied to show the best materials
for optical filtering. As well as we there deeply investigated the optical signal processing of
optical delay line filter for high speed optical transmission network applications. We have
developed this model to include user defined bit sequence generator which is provided to the
amplitude modulator instead of electro-optical modulator. Rectangular optical filter at line
transmission is employed with low pass Chebyshev filter instead of low pass Bessel filter in
this model. Maximum quality factor and minimum bit error rates are the major interesting
performance parameters in our comparison for different network applications using optiwave
simulation version 13.
The modified and proposed model based optical wireless communication channel for
different optical filters are implemented and compared with the previous model. Different
optical filters can be used that namely Bessel, Trapezoidal, Gaussian and Fabry Perot Optical
Filters in our simulation. Our results has presented maximum quality factor in compared with
the previous model in terms of both optical range and beam divergence. The proposed model
has achieved maximum quality factor with different optical filters in terms of optical range,
transmitter and receiver aperture diameters. It is found that maximum quality factor can be
enhanced with using Gaussian optical filters in comparison with different optical filters.
