In this article, a novel architecture for full duplex wired and wireless network with optical fiber backbone network is proposed. We employ a dual drive dual port Mach-Zehnder modulator to simultaneously modulate the CW laser source with wired and wireless data, for the downstream link. Light remodulation technique using RSOA is utilized in the upstream(More)
Motility is one of the most important characteristics associated with the fertilizing ability of spermatozoa and is an expression of their viability and structural integrity. Computer-assisted semen analyser (CASA) provides precise and accurate information on different sperm motion characteristics. This article reviews various aspects of computer-aided(More)
In this article, an all optical device for reduction of transients in broadband Raman amplifiers caused due to channel switching in reconfigurable networks is presented. The passive device employs Self Phase Modulation (SPM) with filtering to effect this control. Si<sub>3</sub>N<sub>4</sub>-SiO<sub>2</sub> waveguide is designed and simulated to create a(More)
Satellite communication has greatly augmented the boundaries of science and technology. The RF subsystem is a pivotal component which has evolved tremendously over the years. This paper compiles neoteric developments of microwave components in the RF subsystem of satellites. The designs and results of some key components like Low Noise Amplifier (LNA), High(More)
