Özet:

 

The bent waveguide is a key element for integrated optical  signal processing waveguide devices.  We propose a new type of  two-dimensional photonic crystal L-shaped bent waveguides with  additional pillars at the corner.  Using the FDTD method based on the  principle of multidimensional wave digital filters we simulate its  transmission characteristics and show an excellent transmission of  light in L-shaped bent waveguide.  As an application we design compact  size multi/demultiplexer composed of the L-shaped bent waveguides and  directional couplers and realize multi/demultiplexer with  low-insertion loss and high extinction ratio device whose size is of  the order of the wavelength of light.
