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 with sheet like shape technology using diffusion controlled light transmission in the multi- planar waveguides that makes capability of broadcasting, simultaneous bidirectional transmission, easy alignment and plural multiplex transmission. We have fabricated a basic model using optical sheet bus technology for the first time and evaluate them at 500MHz clock operation as follows: (1) synchronous broadcasting transmission to control transmission delay; (2) simultaneous bidirectional transmission in the same waveguide; (3) multiplex transmission such as time division multiplexing, wavelength division multiplexing and so on. Through this fabrication and evaluation, we can pick up some approach to put the optical sheet bus technology into practice with feature as follows: (a) simple design rule for multi-accessible bus systems like as shared memory bus systems, which needs faster speed; (b) added-value of multiplex transmission ways that reduce circuit frequency, minimize power consumption, maximize transmission bandwidth, and bring about no-wait communications for the bus systems.
