Solid–liquid modulator via phononic crystal-based Mach–Zehnder interferometer

This study investigates a sensitive chemical and hazardous greenhouse gas sensor using ternary phononic crystals composed of periodic tubes. The sensing mechanism depends on the localization of the topological edge state at the interface between phononic crystals. The impact of the structure's geometry and concentration of a specific gas in air are discussed. Further, the effect of temperature on the position of topological edge state and the sensitivity of the proposed sensor will be studied. This model has shown good sensitivity of 1.58 Hz m-1 s and a figure of merit of 33.7 m-1 s to distinguish different chemical and hazardous greenhouse gas. Furthermore, the proposed detector is low-cost and simple because it does not require a complicated procedure to fabricate multilayers with different mechanical properties.

Here, we investigate a gas sensor model based on phononic crystals of alternating tubes using the transfer matrix method to detect hazardous greenhouse gases. The effect of the thicknesses and cross-sections of all tubes on the performance of the proposed sensor is studied. The results show that longitudinal acoustic speed is a pivotal parameter rather than the mass density variations of the gas samples on the position of the resonant peaks due to its significant impact on the propagation of the acoustic wave. The suggested sensor can be considered very simple and low-cost because it does not need a complicated process to deposit multilayers of different mechanical properties’ materials.

Sagnac interferometry (Mach-Zehnder type) has been used for the self-Kerr nonlinearity (SKN) dependent photon drag. The presence of SKN results in an improvement in the light drag angles from±10 micro-radians to±1 centi-radians. Additionally, the system exhibits Electromagnetically induced transparency (EIT) with the presence of SKN. Optical angular momentum (OAM) dependency in the probe ﬁeld is introduced for controlled light dragging by allowing it to pass through a spiral phase plate. Improved positive and negative group indices are noticed respectively, in the presence and absence of SKN. Consequently, reduced relativistic group velocities for the propagating beams are observed when SKN is present in the system. The outcomes displayed has the potential to be used in many diﬀerent sensing schemes.
