Photonic crystal assisted 90° waveguide bend

Sözüer, Hüseyin Sami; Şengün, Hediye Duygu (World Scientific Publishing, 2011-06)

The 90° waveguide bend is an important component of optical circuit applications. We propose several models for such a bend, some of them assisted by a two-dimensional photonic crystal with a bandgap in the desired range ...
Photonic crystal assisted L-shaped waveguide bend

Şengün, Hediye Duygu (Izmir Institute of Technology, 2009)

Photonic crystals are periodic dielectric structures. This periodicity allow us to manipulate light in ways that have not been possible before. As a result, photonic crystal waveguide components play a significant role in ...
