In this thesis, an optical backplane interconnection has been implemented with transmission diffraction gratings as a channel. Masks of diffraction gratings were made by the E-beam lithography with 1$\mu$m resolution. Transmission diffraction gratings have been made on DCG(dichromated gelatin) by Ar laser exposure of the masks. The gratings made by the above process, have advantages of easy fabrication and needlessness of wavelength compensation. The clock distribution system and the data tranceiver have been implemented as an example of optical backplane interconnections. The interconnection systems were insensitive to wavelength variation of the laser diode which was caused by temparature or power fluctuation.
