Abstract

The Photonic Crystal (PC) taper integrated between Single Mode Fiber (SMF) and photonic device for optimum power coupling for different waveguide lengths (8 μm and 0.99 μm) is designed and analyzed. Different geometries of the taper such as triangular, rectangular and Butt coupler are considered for investigation. The transmission efficiencies of different waveguides based on the taper length (TL), waveguide starting (WS), waveguide ending (WE), and inlet waveguide width (WI) geometry are investigated. Triangular taper design couples the strong electric field which provides higher transmission efficiency of around >90, spectral wavelength of a 0.2 nm, channel spacing of 0.4 nm, and crosstalk of �53 dB. © 2020, Springer Nature B.V.
