Nanofiber Integrated with Quantum Dots
TOKYO, Dec. 29, 2104 — A research team from the Center for Photonic Innovations at the University of Electro-Communications has integrated quantum light sources with nanofibers, a possible step toward a quantum Internet. A computer-controlled picoliter liquid dispenser and an inverted microscope were used to deposit individual quantum dots along the fiber, which is 400 nm in diameter and has 99 percent light transmission. The dot deposition resulted in spatial accuracy better than 3 µm and photon
