Abstract
Conventional electrical bus system technologies are encountered their physical borders in terms of transmission length and parasitic capacity of lines, and thus, many optical interconnection technologies are proposed to solve the problems in the electrical circuits. In this paper, we propose a new optical bus (we call "optical sheet bus") technology using diffusion controlled light transmission in the stacked planar waveguides that makes capability of multicasting, simultaneous bi-directional transmission, easy alignment and plural multiplex transmission. We have fabricated basic models using optical sheet bus technology and evaluated those characteristics.
