Lower- and higher-order nonclassical properties of photon added and subtracted displaced Fock states

Abstract: Nonclassical properties of photon added and subtracted displaced Fock states have been studied using various witnesses of lower- and higher-order nonclassicality. Compact analytic expressions are obtained for the nonclassicality witnesses. Using those expressions, it is established that these states and the states that can be obtained as their limiting cases (except coherent states) are highly nonclassical as they show the existence of lower- and higher-order antibunching and sub-Poissonian photon statistics, in addition to the nonclassical features revealed through the Mandel $Q_M$ parameter, zeros of Q function, Klyshko's criterion, and Agarwal-Tara criterion. Further, some comparison between the nonclassicality of photon added and subtracted displaced Fock states have been performed using witnesses of nonclassicality. This has established that between the two types of non-Gaussianity inducing operations (i.e., photon addition and subtraction) used here, photon addition influences the nonclassical properties more strongly. Further, optical designs for the generation of photon added and subtracted displaced Fock states from squeezed vacuum state have also been proposed.

Vehicle Pollution Monitoring, Control and Challan System Using MQ2 Sensor Based on Internet of Things

Abstract: In the automobile sector, the new advancements in technology help the vendors in developing smart vehicles. These smart vehicles are designed to provide all sort of comfort to the society. But still, some improvements are required to make these vehicles smarter in terms of environmental pollution management. The other cause of air pollution is due to the toxic gases released by the industries. The environment pollution is still increasing gradually despite the various efforts of government. A number of solutions are available in the literature to control and monitor environmental pollution. The examination uncovers that there is a necessity of a sensor based embedded system that can screen and control the air contamination with generation of challan from anyplace in the world using IOT. An embedded system prototype has been designed on the concept of an internet of things scenario that uses sensors and actuators around Raspberry Pi board. The system prototype is programmed in python using some standard libraries available on adafruit and github. A web page is also designed to monitor the level of gases remotely at any place in the world. The results demonstrate that the complete system has been successfully tested and implemented.

Porous photonic crystal structure for sensing applications

Abstract: A multilayer photonic band gap structure is proposed for sensing applications in visible wavelength range. The structure is designed by introducing alternate layers of dielectric material on a glass substrate. To ease the analyte infiltration and to improve the sensitivity, porosity is introduced deliberately within each layer. Extensive analysis is carried out to optimize the number of dielectric layers, their thickness, and percentage of porosity. The transmission/reflection spectral characteristic and sensitivity of the proposed structure are analyzed by a three-dimensional finite difference time domain method. The porosity value and structural parameters are optimized to obtain highest possible sensitivity. The proposed structure exhibits a 0.05-nm shift in reflection/transmission wavelength with corresponding refractive index change of 10 − 3. Analyte can also be distinguished by seeing the sample color change with naked eyes. Thus, multiparametric characterization of the proposed structure demonstrates its potential for sensing applications.
