Abstract

A computer code for the design of optical sensors is developed, the electromagnetic model taking into account both lossy guided and leaky modes. For a concentration C = 700 ppm of toluene in water, the maximum absorbance of a sensor having length L=2 cm is A ≡ 10 for the guided quasi-TM₀₀ mode, while that pertaining to the leaky quasi-TM₁₂ mode is A ≈ 1200. The simulation results indicate that a selective excitation of the suitable propagation modes could enhance the sensor performance.
