| 520 | |a Fiber optic brings tons of contribution to the world for its various uses and photonic crystal fiber (PCF) is one of the latest inventions in the field of fiber optics. This research concentrates on one of the emerging field in PCF family which is sensor. Most of the PCF are fabricated with lots of airholes arranged in a structured way with four or five or six layers of airholes surrounded the central region of the fiber. The primary focus of the study is to design a relatively simple structure PCF sensor which requires less design complexity and easy for fabrication. The design proposed in the study has three different pairs of airholes with different diameter which has similarity with conventional PANDA type fiber. Birefringence used as the prime factor in this research to detect pressure. To achieve high birefringence which leads to more sensitivity with this simple design is a challenging task and this is the main motivation which made possible this research come to daylight. Using relatively simple design structure is a difficult job to gain high birefringence which was achieved in this study. For achieving high birefringence, the geometry of symmetry breaking of the fiber structure method is applied here. Breaking more symmetry brings more birefringence. The sensing analysis using birefringence is covered in the study and it gives a meaningful response wavelength shifting from operating wavelength. From the design proposed in the study, birefringence achieved is as high as which is highest as far as known. The maximum sensitivity achieved for a certain design parameter is 38.95 nm/MPa for 1mm long PCF. But by changing and altering various design parameters, the maximum sensitivity found is 57.09 nm/Mpa for 1mm long PCF. The sensitivity achieved in this study may vary if the size of the sensor is varied. The longer the size, lower the sensitivity. | ||
