Performance Study of Parabolically versus Exponentially Tapered Multimode Interference CouplerBy 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 …
