“…The purpose is to reduce, because the straight and bent waveguide mode field locations in the heart pattern do not match the transmission loss caused by [31]. Offset structure can effectively reduce losses caused because the pattern does not match [32], but, for photolithography and etching, it has superior precision requirements.…”

The Design of Large Curved Waveguide Based on Sunflower Graded Photonic Crystal

In this paper, three large curved waveguides based on Sunflower Graded photonic crystal are designed. Numerical simulations of electromagnetic beam bending in Sunflower Graded photonic crystals have shown that homogenization based on the Maxwell–Garnett theory gives very good results for steering the electromagnetic field. In contrast to the progressive bending waveguide structures based on periodic photonic crystal designs reported in the literature, this structure is not only simple in design, but also the optical wave trends in the progressive bending waveguide structures are more smooth. Sunflower structures, due to their high circular symmetry, have a great advantage in making arbitrary curved waveguides. The results have some theoretical implications for the design of optical integrated circuits and the selection of optically thin communication devices. It is also useful for the selection of meta-materials.
