Abstract :
The letter proposes an integrated N × N tree-structured optical switch matrix. The geometrical design considerations are described. Switch elements and connecting waveguides are arranged so that the required matrix length is almost as short as possible. The calculated length of the LiNbO3 switch matrix is shorter than that of the conventional crossbar matrix.
