Abstract: (3363 Views)
The purpose of this article is to design optical sensors with composite clad and high sensitivity, the effective medium theory was applied to slab waveguide, and, using a suggested model, a Fiber Bragg Grating is located in an specific length of composite clad of slab waveguide and effects of strain and temperature on the wavelength of the sensor and reflection and transfer based on wavelength is analyzed. It is observed that with apply strain and temperature, the reflective index has an increasing trend and reflection tends toward high wavelength, infrared area.
Keywords: Fiber Bragg Grating, Effective Reflective Index, Optical Fiber Sensor, Slab Waveguide, Composite Clad, Strain
