Profile
Summary
Rajeev Ranjan was born in India. He received the master’s degree in engineering physics from the National Institute of Technology Warangal, Warangal, India, in 2011. He joined Siemens Corporate Research and Technologies, Bangalore, India, as an Intern. Then, he joined the ISRO, India (Indian Space Research Organization, Laboratory of Electro Optics System), where he was engaged in research on the applied optics area. There he was responsible for the fabrication of bulk optics for space applications. Here he was also responsible for the interferometric test of the surface figure accuracy of the space borne optics. He gains an experience on working with Fizeau Interferometer for testing flatness and surface accuracy at ISRO. He also put on his hand experience on the optical system design using different optical designing tools (Zemax, Code-V).
In 2014 he joined the Department of Engineering, University of Naples “Parthenope” Naples, Italy, where his research focused on electric arc discharge technique used for the fabrication of Long Period Gratings Sensors in different kinds of optical fibers. In this project, he was responsible for fabrication of Long Period Gratings Sensors in different kinds of optical fibers starting from standard Corning SMF, specialty fibers and to the new generation solid core photonic crystal fiber. Sensors fabricated by him have been applied for real time gaseous sensing at Italian/European Railways. His sensors were also tested for gamma radiation sensitivity of in collaboration with European labs (National Institute for Laser Plasma and Radiation Physics). These sensors went under the radiation test. His research resulted in several conferences presentations and journal publications including in Nature Publications (Scientific Reports), Photonics Technology letters. Currently he is working on label free biomedical non-linear imaging at National Research Council (CNR), Institute for Microelectronics and Microsystems.
