Iran Acquires Technical Know-How for Production of All-Optical Switches for Long-Range Communications
“What has been proposed in this research is the combination of atomic and plasmonic resonance phenomena to reduce costs and increase productivity,” said Maliheh Ranjbaran, the main researcher of the project.
“This combination creates new capabilities in the engineering of spectral properties of materials,” she added.
Noting that all-electric switches like transistors are the basis of the structure of digital circuits, Ranjbaran said, “Since in today world, long-range communications are based on optical fibers, the processes of converting optical signals into electrical signals and vice versa are essential when receiving and sending information.”
“Due to the need of this industry to highly rapid and numerous conversion processes, there is a need to use all-optical tools. All-optical devices have attracted much attention in quantum communication due to their lower cost, higher speed, and smaller dimensions,” she underlined.
In a relevant development in September, a group of Iranian engineers at a knowledge-based company had also produced optical fiber-based sensors which can monitor railroads and energy transmission lines and control traffic at the borders by showing the person's position on the map.
“This project was carried out with the aim of indigenizing one of the newest and most state-of-the-art technologies in the world which is the development of optical fiber sensors,” said Mohammad Hossein Maleki, the project manager of the knowledge-based company.
“In this project, we converted fiber optics into a sensor and we analyzed the data obtained from this sensor by using artificial intelligence,” he added.
Maleki stated that these fiber optic sensors have wide applications, and added, “One of the applications of this sensor is in the borders. Monitoring of energy transmission pipelines, power lines and railways can be carried out with this sensor since they are able to monitor attempts to steal and the breakdowns of trains and rails and the speed of trains.”
