Abstract

A bent photonic crystal waveguide was fabricated by use of a lattice pattern of a circular photonic crystal that allowed high transmission for a broad band of wavelengths with a small radius of curvature at a bend. The waveguide was fabricated by use of alumina rods with a diameter of 3mm. Windows of high transmission as a result of waveguiding were observed near 9 and 15GHz. By measurement of the relative wave intensity E2 along the line defects, the propagation losses in the straight and the bent sections were estimated at 9.3GHz to be 0.04 and 0.03dBmm, respectively.
