Paper Abstract

We present in this work the study of metal insulator metal (MIM) structures on waveguides for hydrogen leak sensors. The configuration is based on a transducer layer deposited on the core of a multimode fiber optic. The reference transducer layer is a multilayer stack based on a silver, a silica and a palladium layer. The spectral modulation of the light transmitted by the fiber allows to detect hydrogen. The sensor is only sensitive to the transverse magnetic polarized light and the transverse electric polarized light can be used as a reference signal. The multilayer thickness defines the sensor performances in terms of sensitivity, SNR and time response. The silica thickness tunes the resonant wavelength, the silver (or gold) supports the plasmon and the palladium detects the hydrogen gas in the environment. This study synthesizes the sensor performances as a function of different parameters such as the sensitive materials, different thicknesses, numerical aperture, etc. and goes towards very promising nano-detectors based on the use of original nanoparticles.
