Design of a Thickness Sensor Based on a One-Dimensional Phononic Crystal
we have analyzed a one dimensional phononic crystal made by the stack of N bilayers of
(LiNbO3/SiO2). The sensor design consists of a one dimensional phononic crystal structure
with a defect layer inserted in the middle. Using the Transfer Matrix Method (TMM), the
transmission spectrums of acoustic waves are calculated and plotted. In this work, we are
interested in the resonance peak that is transmitted inside the phononic band gap. The
results obtained show clearly that the resonant frequency of the measured transmission
peak is very sensitive to the layer defect properties. This proves that such structure offers
a new platform for sensing applications.

Boosting faraday rotation in a one-dimensional coupled resonator magneto-plasmonics structure made by silica matrix doped with magnetic nanoparticles
resonator magneto-plasmonics by a metal cover layer. To this purpose, we used SiO2/ZrO2 or SiO2 /TiO2
crystals doped with magnetic nanoparticles by sol-gel process in different configurations and a gold layer of
10 nm thick for the excitation of the surface Plasmon Polaritons (SPPs). Based on Tamm plasmon, a wide
range of wavelengths is detected by which the merit factor increases due to the interaction of light with the
Tamm plasmon and surprisingly the optical window in this region in addition to the main resonance. These
structures offer the opportunity to improve the performance of magneto-optical devices.

Boosting Faraday rotation in a one-dimensional coupled resonator magnetoplasmonic structure made by silica matrix doped with magnetic nanoparticles
resonator. To this purpose, transfer matrix method was used where crystals made by SiO2/ZrO2 or SiO2/TiO2 doped with magnetic nanoparticles using sol-gel process in
different configurations and use and 10-nm thick gold or silver layer for the excitation of the surface plasmon polaritons (SPPs). Tamm plasmons are surface modes that
result from forcing the field to be confined at the metaldielectric interface via a method different than total internal reflection. Optical Tamm states can be formed in both
the TE and TM polarizations. Based on these modes, a wide range of wavelengths is detected by which the figure of merit increases due to the interaction of light with Tamm
plasmons and surprisingly the flat optical window in this region in addition to the main resonance. These structures can open a new gate for enhancing performance of the
magneto-optic devices.

Phononic band gap of longitudinal acoustic waves in one-dimensional crystal for ultrasonic applications
various domains. In this work, we have analyzed phononic
band gaps of one-dimensional phononic crystal made by a
stack of N bi-layers of LiNbO3/SiO2. The transmission
spectrum of acoustic waves is calculated by using the
transfer matrix method (TMM).
The results clearly demonstrate the existence of phononic
band gap of which the position and the width are strongly
affected by many physical parameters. Our results are useful
in various applications such as acoustic barriers and sensor
materials.

Existence of high Faraday rotation and transmittance in magneto photonic crystals made by silica matrix doped with magnetic nanoparticles
ZrO2 matrix to produce high-performance one-dimensional magnetophotonic crystals (MPC) and
to solve the problem of integrating magneto-optical devices. Given the importance of the magneto-
optical Faraday effecton most non-reciprocal optical components, we studied the influence
of different 1D structures on Faraday rotations.The potential of these structures offers a wide
range of applications in the field of miniaturized and integrated non-reciprocal devicessuch as
isolators.

Magneto-Photonic Crystal Micro-Cavities in One Dimensional Photonic Crystals Fabricated by Sol Gel Process
SiO2/ZrO2 or SiO2/TiO2 doped with magnetic nanoparticles using the sol–gel process. The studied structure
consists of a multilayer of SiO2/ZrO2 or SiO2/TiO2 and air gap with lattice constant a= 0.70 m. The structure
is characterized by a background refractive index of 1.51. We started by introducing one defect at different
locations, then we followed by two and three defects at different locations. The results obtained show clearly
that these magnetic micro-cavities may serve as a fundamental structure in a variety of ultra-compact magneto
photonic devices such as optical isolators and modulators in the future.
