Simulative Investigation of RoF and FSO Based Hybrid Network with Different Types of Fibers
Abstract: Free-Space Optics (FSO) is a communication network in which free space work as a channel between transceivers and uses line-of-sight technology and it uses a laser to deliver optical bandwidth association. At present, the FSO system is able for transmission of data, audio and video messages through the environment, permission for optic connectivity not having need of fiber optic cable or protecting spectrum licenses. FSO network can operate over distances …

Optical Heating Ability of Er3+-Yb3+ Embedded TeO2-WO3 Glass for Thermometric Applications
Abstract: The present research work details laser-induced optical heating ability of the Er3+-Yb3+ embedded TeO2-WO3 glass prepared by the melt-quenching process. The green upconversion emission observed through the 2H11/2→4I15/2 and 4S3/2→4I15/2 transitions of Er3+ ion upon 980 nm diode laser excitation was used to employ fluorescence intensity ratio technique. The results obtained from temperature sensing study were utilized to monitor temperature against pump power provided. The internal heating generated up to …

Optimization of a Hybrid Core Photonic Crystal Fiber for THz Applications
Abstract: Despite several real-life applications, the development of low-loss terahertz waveguide is still a challenge for long-distance applications due to its low confinement and high propagation loss. In this paper, an octagonal waveguide structure has been optimized for minimum propagation loss in the THz frequency band. The optimized structure has a core diameter of 300 um with an operating frequency of 1.1 THz. From the optimized structure, we found optimized power …
