Research Interest

  • Theoretical investigation of electromagnetic bandgap structures (Photonic crystals) for communication applications – Development of devices for DWDM (Dense Wavelength Division Multiplexing) and CWDM (Coarse Wavelength Division Multiplexing) technologies.  
  • Computational Electromagnetics – Various methods for design and modelling of integrated optical devices for sensing and optical communication applications.
  • Terahertz photonic crystals – Terahertz radiation bridges the gap between microwave and optical regime. It can penetrate into most of the materials and has smaller wavelengths compared to microwaves ensures interrogation of smaller sample volumes. Ability of phonic crystals to strongly confine EM radiation for longer durations can be explored at terahertz range frequencies, at which most of the biological activities happen.
