Theoretical Modelling and Design of Photonic Structures in Zeolite Nanocomposites for Gas Sensing: Part I - Surface Relief Gratings
Abstract
The suitability of holographic structures fabricated in zeolite nanoparticle-polymer composite materials for gas sensing applications has been investigated. Theoretical modelling of the sensor response (i.e. change in hologram readout due to a change in refractive index modulation or thickness as a result of gas adsorption) of different sensor designs was carried out using Raman-Nath theory and Kogelnik’s Couple Wave Theory. The influence of a range of parameters on the sensor response of holographically-recorded surface and volume photonic grating structures has been studied, namely phase difference between the diffracted and probe beam introduced by the grating, grating geometry, thickness, spatial frequency, reconstruction wavelength and zeolite nanoparticle refractive index. From this, the optimum fabrication conditions for both surface and volume holographic gas sensor designs have been identified. Here in part 1, results from theoretical modelling of the influence of design on the sensor response of holographically-inscribed surface relief structures for gas sensing applications is reported.
