The performance of one-dimensional photonic crystal for plasma cell application is studied theoretically. The geometry of the structure can detect the change in the refractive index of the plasma cells in a sample that infiltrated through the defect layer. We have obtained a variation on the resonant peak positions using the analyte defect layer wi...

In this article, we analyze the bit error rate (BER) performance of the multiple-input multiple-output (MIMO) based free-space optical (FSO) link by adopting Gamma–Gamma (GG) distribution with atmospheric turbulences (ATs) and pointing errors (PEs). By expanding the GG distribution, the complexity is high due to Meijer-G function with MIMO. To redu...

To achieve super-resolution imaging, the information in higher frequency of the observed sample is collected by illuminating with a structure beam for a limited optical transfer function. In this paper, tilt illumination mode is introduced to structured illumination microscopy (SIM) for enhancing lateral resolution. More sample spectrum more than t...

Phthalocyanines are of a broad interest in photovoltaic applications. In this study, films of titanium-phthalocyanine-chloride (TiPcCl2) were prepared by the thermal evaporation method. The molecular structure was studied by a Raman spectrometer, showing a match between the spectra of the powder and the prepared films. The films' surface was examin...

Fill factor (FF) deficit and stability is a primary concern and challenge with the perovskite solar cell. The band alignment and resistance at the junction interface further decreases the fill factor and thus limits the performance of the device. Moreover, degradation of the intrinsic properties of the upcoming perovskite material such as methylamm...

We present a new method for generating a 4 to 25 ms high power acoustic harmonic bursts, reaching more than 110 dB Sound Pressure Level (SPL), from the spherical Helmholtz resonators. The method uses Q-switched Nd:YAG laser pulses (wavelength = 1064 nm, pulse width = 6 ns, and energy = 450 mJ) to induce plasma shocks inside an AISI 316L stainless s...

This study performs two recent methods on the nonlinear long-short wave interaction system (NLSWIS) to obtain novel formulas of solitary solutions representing an optical field that does not alter by multiplication a sensitive balance between the different terms impacts in the medium. Elastic medium is defined as the medium that can adjust in the f...

An optoelectronic oscillator (OEO) configuration with a unique optical fiber length, followed by a dual-loop in the radiofrequency (RF) domain is proposed and studied. Such a configuration with a unique optical delay followed by an RF time delay enables a reduction in the intensity of unwanted frequencies and a remotely fine frequency tuning. The R...

We propose and analyze a classifier based on logistic regression (LR) to mitigate the impact of nonlinear phase noise (NPN) caused by Kerr-induced self-phase-modulation in digital coherent systems with single-channel unrepeated links. Simulation results reveal that the proposed approach reduces the bit error ratio (BER) in a 100-km-long 16 quadratu...
