Abstract
We have been developed the planar optical approach[1-3] in order to
implement multistage interconnection networks (MIN) on a single glass
block. Planar integrated optics composed of free-space optical
components integrated on a glass block makes signal connections
between 2-dimensional (2-D) arrays of input and output optoelectronic
devices via 3-D glass space. Cascading operation in the optical
multistage interconnections is based on the combination of signal beam
array and clock beam array at the node stages[4], however, it has
remained as one of the challenges to be solved to the planar
integrated optics.
