ABSTRACT:
The present invention discloses an optical back-board interconnection module scheme applying optical technique in a back-board interconnection module scheme for distribution of communication signals among opto-electronic integrated circuit (OEIC) boards of data communication network or computer systems with ultra-high speed.
The present invention provides a back-board interconnection scheme having out-coupling uniformity level of optical power of below 1% and total out-coupling efficiency of more than 99%, and a method for designing a focusing grating coupler (FGC) array used as an important component in the back-board interconnection scheme and FGC standard specification obtained by such a method. When the inventive module is applied to the back-board interconnection scheme to couple communication signals with ultra-high speed performance among a plurality of opto-electronic integrated circuit boards in the high speed data communication network or high speed computer systems, optical signals transmitted through data bus lines at an ultra-high speed of more than several gigabits per sec. may be distributed to a plurality of OEIC boards. Moreover, the number of data transmission lines that may be integrated per unit area may be increased.
