A steady-state model of a strained MQW-SOA is described. Least-squares fitting of the model to experimental polarization resolved amplified spontaneous emission spectra is used to obtain difficult to measure model parameters such as the line-broadening lineshape parameters, Auger recombination, bandgap shrinkage, and intervalence band absorption coefficients. Well capture and escape processes are modeled by a carrier density dependent net escape time which accounts for barrier effects. Simulations and comparisons with experimental data are given which demonstrate the accuracy and versatility of the model.

A Cloud Native Approach to 5G Network Slicing

  • Francini A.
  • Miller R.
  • 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 ...
