In this simulation study, the response of fiber Bragg grating (FBG) sensors is investigated and optimized. Uniform and nonuniform FBG spectra with new component are suggested by fine selection with (COMSUL program) and compared theoretically under the effect of several external strain values (0.005, 0.006, 0.007, 0.008, 0.009 and 0.01). These two types operation have been examined by the Optisystem programmer. The measured sensitivity was based on VCSEL laser source with operation wavelengths of 1650, 1600, and 1550 nm via non-uniform and uniform configuration. The achieved sensitivity was found to have different values; 5.7, 2.6, and 1.77, while the highest observed sensitivity value is recorded at a wavelength of 1550 nm. Accordingly, this wavelength was chosen to advance the study. Temperatures of 20, 30, 40, 50, and 60 degrees Celsius were applied. Measured sensitivity between them varied, and satisfied the following functions: sine, Gauss, and Boltzmann indicating altering in sensor responses.
