  Performance Study of Parabolically versus Exponentially Tapered Multimode Interference Coupler

  By Santosh Kumar, S. K. Raghuwanshi

  Abstract: ABSTRACT This paper shows mainly the performance study on tapered section of Multimode Interference (MMI) coupler having either parabolic or exponential taper section. The comparative study of the 1 × 2 MMI coupler with proposed structure, such as the normalized width variation, and variation of MMI length are investigated by the 2D finite difference beam propagation method (BPM). We have found that exponential tapered MMI coupler has advantageous compared to …

  Design of Plasmonic Based Splitters for WDM Applications

  By Santosh Kumar, Lokendra Singh

  Abstract: AbstractPlasmonics has special property of metallic nanostructures to allow manipulation and routing of light at nanoscale. In this paper, 1×2 and 1×4 splitters are designed using metal-insulator-metal (MIM) plasmonic waveguides. These proposed splitter designs could be used to conquer various filtering devices for high assimilation in surface plasmon polaritons based metallic surfaces. The results are verified using finite difference time domain (FDTD).Keywords: Plasmonics waveguides, surface plasmons, finite difference time domain …
