        NJUPT professors have obtained two US patent authorizations

        Lately, the research results of NJUPT Professor Wang Yongjin’s team have obtained two US authorizations.

        Professor Wang Yonglin’s team has long been engaged in the research of compound semiconductor homogeneous integrated optoelectronic chip. In the process of research, the team found the coexistence phenomenon of quantum diode light detection, and developed the homogeneous integrated optoelectronic chip for the first time. What’s more, in this study, a full duplex optical communication and processor–optical interconnection memory system based on homogeneous integrated optoelectronic chips is completed. These results have attracted wide attention in the industry, which leads to continuous reports from National Science Review and Semiconductor Today.

        In order to protect the research results, Professor Wang Yongjin's team actively carried out patent layout at home and abroad. In 2016, two overseas patent applications were initiated through PCT (Patent Cooperation Treaty). After the international stage and national stage, they were finally authorized by the United States.The authorizations of these two patents further strengthen China's leading position in the field of homogeneous integrated optoelectronic chips, and effectively protect the intellectual property rights independently developed in this field.
