Abstract :
Two types of waveguide power splitters based on a bending multimode waveguide are demonstrated for an unbalanced power splitting ratio. An arbitrary splitting ratio is achieved by choosing the bending radius and the length of the multimode section appropriately. Experimental results show that the fabricated devices have wide bandwidth.
