Dispersion and Modal Behavior of Different Optical Fiber Materials at Different Temperatures

We have the pleasure, at this final stage of our thesis, to thank some of the exceptional people who helped us throughout the thesis. Firstly, we would like to thank our supervisor Dr. Md. Shah Alam, professor, department of EEE, Bangladesh Engineering University and Technology (BUET), whose emphatic guidance, instruction and supervision motivated us to work on this subject. It is he who persuaded our intrusive mind to bring out some dynamic result of our work. Without his sensible and prudent judgment and observation, we could hardly fulfill our job. We are grateful to Dr. Satya Prasad Majumder, Professor in the selection grade, Department of Electrical, Electronic and Communication Engineering (EECE), Military Institute of Science and Technology (MIST), for his immense help throughout the whole work. We would, however like to thank MIST authority and the faculty members of EECE for broadening their supporting hands throughout the work. iii
