Abstract: (1107 Views)
Implementing two holes on a ridge bus-waveguide provides a Fabry-Perot resonator with the Lorentzian output of light. The optical transfer function for the proposed system was derived using the scattering matrix method. The proposed layout used as a refractive index sensor and results were simulated by Lumerical software using the finite difference time domain method. An extended free spectral range of 140nm and the sensitivity of 46nm/RIU were realized by the system. The superiorities of the proposed system are in its simple design, fabrication feasibility, realizing simultaneous changes in the resonance amplitudes and wavelength spectrum, besides an acceptable sensitivity of the sensor.
