Abstract
As one of the most competitive materials of the integrated optics, photonic crystals (PCs) have been investigated for more than 20 years since its conception was proposed. In this work, we established a novel structure of the bend waveguide which is composed of photonic crystal (PC) with triangular lattice of air-holes. By optimizing the bend structures, not only the transmission bandwidth of the whole waveguide is greatly improved, but also the transmission efficiency is enhanced. The transmission efficiencies of the wavelengths between 1504nm and 1586nm can reach more than 80%. The highest transmission efficiency 95% can be obtained for the wavelength of 1553nm. By simulating the transmission of the optimized bend waveguide, the light wave whose wavelength is 1553nm can propagate effectively.
