Abstract

Germanium-based one dimensional photonic structure is proposed in the present research work to envisage pressure sensor at the signal of 1550 nm. The internal mechanism of the present works deal with numerical simulations, which relies on eight different types of losses (absorption, diffraction, dispersion, reflection, radiation, propagation, polarisation and scattering) to compute the transmitted signal emerging from the photonic structure. The sensitivity of the device is also discussed during the computation of the pressure. This pressure variation is accounted for calculating the sensitivity factor for better accuracy. The pressure in germanium-based photonic structure is determined by knowledge of the transmitted intensities.
