We report the performances of a 0.7-µm InP/GaInAs DHBT developed in III-V Lab demonstrating both fT and fMAX of 400 GHz as well as a high fabrication yield and homogeneity on a 3-inch wafer. This technology is used for the fabrication of a very high speed 2:1 multiplexing selector operating up to 212-Gb/s, establishing a speed record. A 5.9-Vpp 112-Gb/s distributed differential Selector-Driver, as well as a 4.3-Vpp 64-GBd 8-Pulse-Amplitude-Modulation (PAM) (192 Gb/s) high-speed power digital-to-analog converter (DAC) and an 18-dB peaking gain at 95 GHz continuous time linear equalizer with up to 200 Gb/s data rate equalizing capacity were also realized in this technology.

© 1963-2012 IEEE. This article presents a packaged SiGe BiCMOS reflectometer for 0.01-26-GHz two-port vector network analyzers (VNAs). The reflectometer chip is composed of a resistive bridge coupler and two wideband heterodyne receivers for coherent magnitude and phase detection. In addition, a high-linearity receiver channel is designed to accommodate 20 ...

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 ...
