Abstract
We present a new approach in the design of a photonic crystal bandpass filter by using waveguide bending. The bandpass filter was designed by introducing two bends with the modified geometry into the both ends of a photonic crystal waveguide. We show that such a filter exhibits step-like spectral profile in the range of 1500-1600 nm, with a maximum transmission of 100%. In contrast to the other designs proposed, the present one does not involve either insertion of small defects or control of cavity-lengths.
