To assess the effect of biotic stress on the germination capability of seeds, laser biospeckle technique was used. Soybean seeds were artificially inoculated by Colletotrichum truncatum fungal spores and irradiated by laser light. Backscattered light from the seed was recorded in the form of speckle patterns and analyzed using subtraction average method of image analysis. It was found that the laser biospeckle technique exhibits strong potential for testing the pathogenicity of various fungi to various germplasm so that the resistivity of the germplasm towards the fungal pathogen can be estimated.

The all-inorganic or hybrid quantum dot light-emitting diodes (QLEDs) employed zinc oxide (ZnO) nanoparticles as electron transport layer (ETL) which led to enhanced performance of the device. The doping strategy of ZnO relies on the fine tuning of the energy levels which improves the charge balance and provides better device characteristics. One such strategy has been incorporated in this work as Magnesium-doped ZnO has been utilized as ETL in designing the QLEDs which facilitates charge balance and suppresses the excess electron injection. This approach provides a new method of incorporating multielement semiconductors with variable bandgaps as ETL.

In this work, we address the Time-Wavelength Division Multiplexed (TWDM) network with multilevel fault correction capability. The network can also serve geographically challenging locations, where either laying out of optical fiber is expensive, difficult or more prone to the faults. In such scenarios, the Free Space optics (FSO) and Radio Frequency (RF) links can be integrated with the fiber links.

In this paper, we made a pioneering effort for the first time to implement Quantum Neural Network regressor model to predict the sensing behavior of Surface plasmon resonance (SPR) sensor and compared the performance of the proposed model with two traditional algorithms namely Support Vector Regressor (SVR) and Artificial Neural Network (ANN) regressor. The proposed trained quantum regressor model is crucial and efficient enough as it could be used to predict the trend of the target value that is confinement loss of the SPR biosensor.

We propose a multi-channel polarization multi-plexed carrier based self homo-dyne (PMC-SH) link with adaptive polarization control by employing wavelength division mul-tiplexing (WDM). This proposed link offers local oscillator (LO)-less reception with simple signal processing requirements which leads to low-cost and low-power solution for terabits short-reach data centre interconnects. Simulations results for 400 Gbps (2 channels, 50 Gbaud/channel, 16-QAM) WDM-PMC-SH link are presented to validate the proposed concept.

We present the method to measure the thickness of multi-layered structure using an indigenously developed SD-OCT system. The SD-OCT system is based on low coherence Michelson interferometry and generates 2D images(B-Scan) with axial resolution of 5 microns. The method developed processes these 2D images in MATLAB and yields information on thickness of each underlying layer in terms of pixels. Samples such as scotch tape and cover slip with known thickness have been used to validate this method. The thickness results obtained using the developed algorithm are in good correlation with the actual physical values within very tight tolerance. This method can be applied to determine thickness of outer paint of aircraft, thickness of fruits, leaves and stems in fruits agro sector besides many other applications.

Method of lines (MoL) is numerically described for analysis of spatial periodic structures based on discrete finite difference hybridization of each transverse plane of multilayer structure. The results show rigorous simulation of the three-dimensional (3D) arbitrary-shaped space grating with the best convergence and high stability for highly conductive metallic layers. We propose our method to be considered for analysis of stacked rotated grating (SRG). Also, we propose time-varying MOL using implementation of the multi-frequency finite difference frequency domain (FDFD) method upon our presented method, so that one can simulate spatiotemporal structures in the hybridization framework faster and much more accurately.

We propose a PZT based acoustic resonator to modulate the refractive index of a Silicon waveguide. We use an inter-digital transducer (IDT) defined on the PZT film to create a standing acoustic wave resonance in the suspended device. We calculate the effective index change from the acousto-optic overlap integral and illustrate its dependency on the IDT pitch.

We propose a unique deep-subwavelength spacer (cavity)-based terahertz (THz) stacked metamaterial to excite Fano resonance emanating without structural asymmetry. Our study shows depletion of Fano resonance intensity with decreasing cavity thickness. This study reveals fundamental relation between resonance hybridization and lattice effect in metasurfaces. We further demonstrate polymorphic resonance hybridization with variation of lattice parameters and materials in the metamaterial cavity near Fano excitation threshold, which can be significant in realization of THz multifunctional resonant devices to control properties of electromagnetic waves.

The simulation results demonstrate that transmittance spectra show red shift while increasing the refractive indices, while the sensing performances of the device offer good sensitivity and figure-of-merit.
