Mr D Lenin Babu from the Department of Electronics and Communication Engineering published his research “A Novel 8-Channel DWDM demultiplexer on Silicon Photonic Crystal slab: Design and Analysis” in Elsevier journal ‘Optik’, having an impact factor of 2.44. This research was carried out under the supervision of Dr Sreenivasulu Thupakula, Assistant Professor, Department of Electronics and Communication Engineering.
Abstract:
The published research presents a novel method to achieve optical information transmission at improved speed and reliability. Multiplexing and demultiplexing are the techniques used to enhance the information transmission rates and effective utilisation of channel bandwidths in communication systems. Dr Thupakula and Mr Lenin Babu proposed a new design with a minimised size of approximately 1mm and reduced information loss.
The team collaborated with the Applied Photonics Laboratory, Department of Electrical Communication Engineering, Indian Institute of Science, Bangalore, to conduct the research.
“The ongoing research is useful not only for communication applications but also for refractive index based sensing applications such as biosensing, Force sensing etc. Our future work includes Integrated optics-based antenna design for THz communication systems, Waveguide devices for sensing applications at THz wavelengths etc.,” said Dr Thupakula.
