Abstract :
A demultiplexer whose input waveguide intersects perpendicularly to one of the output waveguides is proposed and investigated by the finite-difference beam-propagation method. A 1.55-μm-pass/1.31-μm-reflection property is achieved regardless of polarizations. Detailed study of power evaluation is also made on the basis of the Poynting vector.
