“…Consequently, the values that optimize the studied structure with a rectangular taper of L ¼ 3a ¼ 2208 nm are r ¼ 301:76 mm and r=a ¼ 301:76=736 ¼ 0:41. As already stated in previous section, we have also performed the simulations with a triangle shaped taper, which is expected to give better transmission across the working bandwidth (Tran et al 2009;Diaz-Otero et al 2013).…”

We present a two-dimensional study of low-loss photonic crystal defect waveguides built from a III-V type semiconductor-based system surrounded by cylindrical air pillars in a prototypical lattice. Varying the parameters of the lattice, including several taper geometries and lengths in the typical wavelengths usually employed in telecommunications, we perform an extensive statistical survey that determines a parameter map that can be taken as a guide by transmission hardware designers to choose the best lattice geometry in terms of optimum transmittance and minimization of the impedance mismatch.
