“…I. To reduce the impedance mismatch introduced by the EBG structure, a tapering function is used, which is normally employed in Fiber Bragg Gratings (FBG) [36], [37]. The tapering technique is applied directly by modifying the length of the central section in each period Li of the finite structure, as shown in Fig.…”

“…Therefore, it is not mandatory to have uniform periodic RI variation in the FBGs for sensing applications. Apodized FBGs are widely recognized for suppressing the side lobes and various apodization profile along with their side lobe suppression ability was presented by some group of researchers [5,7]. It was reported that the Bessel apodization profile in FBGs has a larger quality parameter and the Blackman profile has maximum sidelobe suppression ability, therefore, these two apodization profiles are recommended for biosensing applications [8].…”

Tapered profiles are introduced in Bessel and Blackman apodized fiber Bragg grating, and their sensing performance is theoretically estimated. Reflectivity equation of proposed apodized tapered profiles is obtained using transfer matrix method and coupled mode theory. Since the effective refractive index of proposed waveguides varies with core radius therefore amplitude distribution and penetration depth of light in surrounding are modified. It is found that exponential tapered profile with Bessel apodization shows higher sensitivity 682.5 nm/RIU, detection accuracy 3858.45, and quality parameter 1718.02 /RIU with minimum FWHM 0.3972 nm of the reflection spectra. Spectral response of the tapered fiber Bragg grating is also analyzed through group delay study. Again, exponential profile was found to be particularly effective, producing less group delay ripples 2.98 ps and is maximum slope of 42.43 degree. Hence, exponential tapered profile is demonstrated for detection of cancer cells lies between the refractive index of 1.3333 to 1.4412.This article is protected by copyright. All rights reserved.

The number of sites and territories in Latvia and across the world that need different kinds of real-time health monitoring (roads, bridges, dams, railways, buildings, and other structures) is constantly growing. Since monitoring often should be conducted at long distances across many locations simultaneously, in corrosive environments under electromagnetic interference or in environments without power supply, FBG can be applied in such types of monitoring. The aim of the Doctoral Thesis is to integrate an optical FBG sensor network in optical fiber communication systems and to evaluate application of FBG sensors in real-time road monitoring solutions.
