A 2:1-selector-driver module with a record differential output amplitude of 5.75 Vpp at 100 Gb/s is reported. It implements a monolithically integrated differential-distributed-amplifier-based driver with a 2:1-selector input stage, realised in a 0.7-µm indium phosphide (InP) double hetero-junction bipolar transistor (DHBT) technology. Broadband input and output transmission lines have been designed and realised on alumina substrate. For compactness and compatibility with existing broadband electro-optical modulator modules, GPPO connectors have been successfully implemented for both 50-Gb/s inputs and 100-Gb/s outputs.

  • Sharma S.

5G networks will have to support a set of very diverse and often extreme requirements. Network slicing offers an effective way to unlock the full potential of 5G networks and meet those requirements on a shared network infrastructure. This paper presents a cloud native approach to network slicing. The cloud ...

Based on the physical model of a bulk reflective semiconductor optical amplifier (RSOA) used as a modulator in radio over fiber (RoF) links, the distributions of carrier density, signal photon density, and amplified spontaneous emission photon density are demonstrated. One of limits in the use of RSOA is the lower ...

How to preserve users' privacy while supporting high-utility analytics for low-latency stream processing? To answer this question: we describe the design, implementation and evaluation of PRIVAPPROX, a data analytics system for privacy-preserving stream processing. PRIVAPPROX provides three properties: (i) Privacy: zero-knowledge privacy (ezk) guarantees for users, a privacy bound tighter ...
