The devices, which have been developed by a group of scientistsfrom the Changchun Optic Fine Machinery and Physics Institute of the Chinese Academy of Sciences, recently passed an official evaluation organized by the science and technology bureau of Jilinprovincial government.

　　The devices are on the way to reaching international standards and can be used as an ideal source of light for the Information Highway, according to experts.

　　A micro-disc light emitting device is a kind of micro-cavity light emitting device with high-integration, lower noise and lowerenergy consumption. One million micro-disc light emitting devicesworking simultaneously use only five watts of electricity.

　　According to Wang Lijun, leader of the research team, the studyon micro-cavity light emitting devices has a high priority in the international semiconductor field. Developed nations like the United States have poured big money into research in the field butChina is lagging behind.
