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. |
