| description | The authors would like to thank Dr. Md. Shah Alam for his coordination, patience and advices through the research. This thesis would not have been completed without his kind support and guidance. We would like to express my gratitude and gratefulness for his instructions, continuous encouragement, valuable discussions, and careful review during the period of this research. His perpetual motivation gave the confidence to carry out this work. We are thankful to him for providing all the necessary information, meaningful discussions and proper guidance.
Our sincere gratitude to the authority of MIST for providing with necessary assistance and allowing to use the university's computers and library resources.
We would also like to pay our solemn regards to our family and friends who supported us generously and encouraged us enormously to complete this job.
Last but not the least we are grateful to the Almighty, without his mercy and help, it would not be possible to complete the job properly and in time. |

In our thesis we have analyzed different types of PCF namely, hexagonal, rectangular and terahertz photonic crystal fibers by a special method known as the finite element method. Photonic Crystal Fibers are promising novel technology with several possible applications in wave guides, nonlinear optics, fiber lasers, sensory systems, ultra-wide-band transmission, supercontinuum generation, high power delivery, optical amplifiers, and other functional devices. Due to these advantages during the last decade, photonic crystal fibers (PCFs) have been extensively studied for these applications utilizing their unique capabilities such as endless single mode operation, modifiable & anomalous dispersion, large mode area, non-linear effects, solitons propagation, high birefringence, and enhanced or suppressed optical nonlinearity. These unique characteristics come from the fact that optical properties of the guided modes in the core can be easily manipulated by changing the structure of PCF. The H-PCF and R-PCF have frequency located in the communication band region and the THz-PCF has frequency located in the THz region. We have discussed about the structure like how the different model are made of; characteristic properties like dispersion, confinement loss, v parameter; their construction etc. For the construction of these models we have used a special software named Comsol, a brief discussion of which is given in one of the chapters. Alongside the properties and the structure, we have obtained different graphs and values like confinement loss and v parameter in order to explain the properties more easily. We have also shown the dispersion properties and discussed the probability of flattened and zero dispersion wavelengths. 2019-03-10T02:33:31Z 2019-03-10T02:33:31Z 2017-12 Thesis http://hdl.handle.net/123456789/411 en application/pdf DEPARTMENT OF ELECTRICAL, ELECTRONIC AND COMMUNICATION ENGINEERING |
