We demonstrate an intelligent symmetric-rate, 8 x 10- Gb/s, bi-directional time and wavelength-division multiplexed passive optical network (TWDM-PON) with 42-km reach, and 1:256 split. 1425-nm laser pump light provides distributed Raman amplification for the upstream channels (allowing lowcost low-power transmitters), serves as a low-rate telemetry channel, and powers an intelligent splitter module that provides supervision for mission-critical services.

Protecting photonic quantum states using topology

  • Blanco-Redondo A.

The use of topology to protect quantum information is well-known to the condensed-matter community and, indeed, topological quantum computing is a bursting field of research and one of the competing avenues to demonstrate that quantum computers can complete certain problems that classical computers cannot. In photonics, however, we are only ...

Digital networks at the nexus of productivity growth

  • Kamat S.
  • Prakash S.
  • Saniee I.
  • Weldon M.

This paper takes a fresh look at the debate over the relationship between digital technology and productivity. The argument of economic historian Robert J. Gordon is that digital technology will not lead to increases in productivity such as we saw in the last century, based on his analysis of the ...
