We show through simulations and experimentally that 112 Gb/s PAM-4 may be transmitted DAC-less using a 28 GHz EML and a novel duo-quaternary detector. Experimental results show that standard FFE/DFE equalization outperforms this technique indicating that it is more suitable for use with a high-speed DAC. Nevertheless, 2 km and 10 km transmission experiments indicate below-FEC performance.

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 ...

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 ...
