Abstract

In this paper, the geometrical design parameters of tapered optical fibers and their effects on sensing of refractive index are investigated. The transmission power of the sensor is simulated by using finite difference beam propagation method. The simulations are run by changing geometrical parameters which are length of transition region, length of waist region and waist diameter. The simulation results show that design parameters strongly affect the sensor performance including sensitivity and sensing range. Moreover, it is shown that the sensing range can be adjusted and also the sensor sensitivity can be enhanced using the optimized design parameters..
