OKI Develops Light Source

Facebook Twitter LinkedIn Email
Telecommunications company OKI Electric Industry of Tokyo has announced its development of a quantum entangled light source that offers the highest purity level achieved to date. The source is based on cascaded nonlinear optical effects using a proprietary periodically poled lithium niobate ridge waveguide device operating at room temperature. Research led by professor Shuichiro Inoue at the Institute of Quantum Science at Nihon University confirms a signal-to-noise ratio more than a hundredfold better than that of optical fiber light sources. OKI will continue to refine the light source. Its goal is to achieve a practical quantum cryptography communications system.
