日本电报电话公司(NTT)、三菱公司与巴特尔纪念研究所(Battelle Memorial Institute)合资建立了一家从事光波导技术商业化的公司。据信光波导技术能使人们大规模生产用于光电子器件的可靠而廉价的光学元件。这些器件用于光通讯、光学测量设备、汽车及飞机上。这个合资经营公司称为光集成研究公司(PIRI),它的成立是由NTT公司的总裁Hisashi Nippon Telegraph and Telephone (NTT), Mitsubishi and Battelle Memorial Institute jointly established a company that is engaged in the commercialization of optical waveguide technology. It is believed that optical waveguide technology enables large-scale production of reliable and inexpensive optical components for optoelectronic devices. These devices are used in optical communications, optical measuring equipment, automobiles and airplanes. This joint venture company is called Optical Integration Research Corporation (PIRI), which was founded by Hisashi, President of NTT Corporation.
