We propose and experimentally demonstrate a fiber-optic sensor for monitoring water salinity in desalination processes with selectable sensitivity. The proposed sensor structure is formed by drilling an air-gap near the cleaved end of a single-mode optical fiber using Focused Ion Beam (FIB) milling. Utilizing the cleaved fiber end as an additional reflective plane, the proposed structure can be simplified as a three-wave interferometer because there are three cavities formed by different pairs of reflective planes. The interference spectrum exhibits three groups of fringes with different sensitivities with respect to the variation of dissolved sodium chloride content in the liquid surrounding the sensor. Therefore, the proposed sensor can measure water salinity with selectable sensitivity depending on the wavelength windows used for spectral interrogation. The temperature effect on the sensor operation was also measured and discussed.

In this paper, an extensive study is performed to understand the effect of the various parameters used in Genetic Algorithms (GA) to solve the spectrum allocation problem in cognitive radio networks. Two utilization functions, namely, Mean-Reward, and Max-Proportional-Fair, are used to evaluate the performance of the GA under different parameters values. Extensive simulation shows that, the parameters of the GA can be fine-tuned to achieve up to 90% and 62% improvements in speed and error, respectively, as compared to the GA used in the literature.

Here we propose an analytical model of energy usage hierarchical wireless sensor network protocols such as LEACH [1]. LEACH has been used as a foundation for much of the wireless sensor network research, so results addressing the underlying nature of these systems build understanding of a wide range of existing protocols. First, we derive the probability density functions of the distance to the nearest cluster head, the distance to the nearest cluster head squared, and the expected number of nodes per cluster. These results are then applied to produce a model of the amount of average energy used per node for each data report. Using this model we give an analytic expression for the optimal cluster-head selection rate. The model is further improved to give an approximate adjustment for distortions in energy usage near the edges of the field. This final model is then compared to the simulation results presented in the original LEACH paper [1] and shown to be accurate. Sensor network protocol researchers can apply results presented here to improve performance of existing systems by making the cluster head selection rate adaptive to external factors.

Wireless and optical broadband access technologies are foreseen to converge by combining the high transmission capacity of the optical communications with the flexibility and the ubiquitous nature of the wireless communications in order to satisfy the growing end-user demand for bandwidth. This hybrid technology eliminates the cost of running fiber to the destination by allowing the fiber deployment until a certain point from where wireless base stations take over to provide service to the end-user. Despite handling the growing end-user demand, new telecommunication technologies are required to be energy efficient. Recently, there is an increasing interest to reduce the energy consumption of the Information and Communications Technology (ICT) sector and the ICT related CO2 emissions. In this paper, we propose an energy efficient design scheme for a fiber-wireless network consisting of a WDM-PON in the optical back-end and a 4G broadband access technology-enabled wireless front-end, e.g. Long-Term Evolution (LTE) or WIMAX. The proposed design scheme uses the average load profiles on the WDM-PON segments and attempts to form power saving clusters (PSCs) which are fiber rings interconnecting several hybrid (fiber-wireless) access networks. Each PSC enables one or more OLTs to sleep and distributes the backlogged traffic among the active segments in the ring. The proposed scheme aims to maximize the number of sleeping segments, and consequently maximize the power saving. Through simulations, we show that the proposed scheme leads to a power saving between 20% and 45% with a maximum of 3.5% increase in the fiber deployment cost by running the interconnection fibers to form PSCs.

Thin film GaN growth on c-plane sapphire (0001) substrate using two-step method by nitrogen plasma assisted MBE is reported. After growth optimization, a low temperature buffer layer was grown followed by the main GaN thin film. The Optical and structural properties of the film were investigated using XRD, Raman spectroscopy, Photospectrometry and in-Situ RHEED. The polycrystalline nature of the grown film containing both wurtzite as well as cubic structures was obtained through XRD. The observed diffused hallo rings in the RHEED pattern confirms polycrystalline structures of the film. Optical band-gap was calculated using spectrophotometry transmission curves. Whereas, the existence of h-GaN and c-GaN phase's were validated by employing high resolution Raman spectroscopy. These results shows that the LO and TO active vibration modes of GaN were due to wurtzite and cubic phases into p-region.

We have investigated the transient thermal behavior and heat distribution in a multi-quantum wells (MQWs) InGaN/GaN lasers diode for λ∼445 nm based on GaN substrate. 2D thermal modeling was performed to estimate the dissipation of heat from the active region. Different thermal designs for planner and solder ball bumps packages have been studied using Al2O3, ceramic-AlN and SiC as submount materials. Comparative study of the planner to that of the solder ball bumps using thermal interfacial materials of Au metallization, AuSn solder, diamond heat spreader and Al block as heat sink. We found that planner package design using SiC as submount can be a material of choice. Furthermore, LIV characteristics show as much as 2 fold enhancement in the output power of the optimized design when operated at elevated injected current ∼1000 mA.

In this paper, we use the finite difference timedomain (FDTD) method to optimize the light absorption of an ultrafast plasmonic GaAs metal-semiconductor-metal photodetector (MSM-PD) employing metal nano-gratings. The MSM-PD is optimized geometrically, leading to improved light absorption near the designed wavelength of GaAs through plasmon-assisted electric and magnetic field concentration through a subwavelength aperture. Simulation results show up to 10-times light absorption enhancement at 867 nm due to surface plasmon polaritons (SPPs) propagation through the metal nano-grating, in comparison to conventional MSM-PD.

A novel method for identifying and discriminating various objects using five different lasers is described. This method uses a laser combination module that allows five laser diodes of different wavelengths to sequentially emit identically polarized light beams through a common aperture, along one optical path. Each laser beam enters a custom-made curved optical cavity for multi-beam spot generation through internal partial beam reflection. The intensity of the reflected light beams from each spot is detected by a high-speed area scan image sensor. Object discrimination based on analyzing the Gaussian profile of reflected laser light at distinguishing wavelengths is demonstrated.

Cloud computing is getting increased attention of the information and communication technologies (ICT) industry recently. The cloud service providers foresee it as a source of promising financial gains, the clients find it a convenient solution where the enterprises may get started on their computing activities without investing on the in-house facilities of hardware and software. They can outsource the computing and archiving activities to the cloud service providers (CSP) though Internet. There are many dimensions of these activities and the researchers are trying to find acceptable solutions for the industry. In this paper, we have focused on the information security issues when migrating to a cloud environment. The confidence of end user can be won partially by the guarantees of service provider and use of cryptographic techniques. It is important that the Intrusion Detection Systems (IDS) should be included in the models which support forensic study whenever required. It is equally important to address the issue of anti-forensic methods that the service providers may use to hide their malicious activities. Therefore the clients would like to have a better, in-depth knowledge of information management at service providers' end. For this purpose tools to probe into the cloud services are required. To elaborate on this issue we have chosen the data archiving and storage model used for medical service providers and hospitals. It is a classic test-case where Patients' history has to be maintained under the guidelines of HIPPA. The Amazon security model has been reviewed for this purpose both for archiving and disaster recovery. An acceptable security model over the cloud architecture is also proposed.
