Prediction of Performance Penalty due to Pump-Signal Overlap in Raman-amplified Systems (SF2L.6, Fri 11:45am PDT)

G. Di Rosa, A. Richter (VPIphotonics), M. Iqbal, W. Forysiak (Aston University)

Abstract: We present an efficient numerical model to predict the performance penalty induced by Rayleigh backscattered light arising from counter-propagating pumps in Raman-amplified ultra-wide-band transmission systems. The model is validated through comparison with experimental findings.

Modelling Weak-Coherent QKD Systems Using a Classical Simulation Framework (ATh1I.4, Thu 9am PDT)

S. Kreinberg, P. Novik, I. Koltchanov, A. Richter

Abstract: We demonstrate how an existing simulation framework for modelling classical optical systems can be utilized for simulations of weak-coherent QKD links.

Adding Artificial Noise for Dynamic Code Rate Matching in Continuous-Variable Quantum Key Distribution (ATh1I.6, Thu 9:30am PDT)

S. Kreinberg, I. Koltchanov, A. Richter

Abstract: CV-QKD over long distances requires high reconciliation efficiencies, hence matching error correction code rate vs. SNR. For time-varying quantum channels, we achieve this by adding a controlled amount of digital noise to the measured data.

Automated Link Loss Compensation and Cost Effective Amplifier Placement in XHaul Optical Network (PS, Wed 4:30pm CEST)

D.Khomchenko, A. Richter, J. Farina

Abstract: Recent growth of interest in the deployment of 5G networks triggers the application of very different technologies in xhaul networks to support the increase in traffic growth and link distances. Critical network design constraints include for instance dense wavelength division multiplexing (D)WDM of channels operating at very different data rates, and the deployment of optical amplifiers and dispersion compensation modules (DCMs) to meet the limited link power and dispersion budget. Cost-optimized planning of such networks requires the optimization of the equipment to be added or minimizing its cost, which becomes a very challenging task when adding the diverse equipment constraints on top of this. In this paper we demonstrate an algorithmic approach that efficiently addresses the link loss and dispersion compensation and equipment allocation problem for xhaul networks. The presented method, which could be part of a comprehensive planning environment, allows optical network engineers to design cost effective amplifier and DCM configurations of superior performance with respect to optical signal to noise ratio (OSNR), received optical power (ROP) and accumulated chromatic dispersion (CD) at the receiver side. Our approach accounts for future channel loading, optical channel path parameters, signal rate, equipment parameters, and constraints arising from the insertion points of amplifiers and DCMs. We demonstrate the convenient operation of our method by designing an exemplary fronthaul network system.

Application-Specific Design and Validation of Photonic Integrated Circuits (Tue 2:05pm CEST)

A. Richter

Abstract: Versatile design tools for integrated photonics and optoelectronics need to support a diversity of technologies addressing very different types of applications. We discuss stringent requirements imposed on them: PICs of increasing size and complexity require circuit-level simulators supporting hierarchical topologies and automation of circuit design. PIC performance testing in target application scenarios requires the seamless integration of circuit- and system-level design tools. An automated design of EO/OE interconnect solutions, especially of importance for telecom and datacom, requires dynamic communication and seamless data transfer between electronic and photonic design tools.

Design challenges of hybrid integrated photonic and optoelectronic circuits (Fri 1pm - 2pm CST / 7am - 8am CEST)

A. Richter

Abstract: Hybrid integrated photonics attracts significant attention, as it enables complete and cost-efficient optical chip solutions for silicon, silicon nitride, and polymer photonics in combination with III-V active optoelectronic devices.
We discuss by means of practical examples design challenges of hybrid PICs. Further, we present a workflow addressing these challenges that relies on standard simulation compact models (as part of foundry-specific photonic Process Design Kits) and a layout-aware design approach. We demonstrate flexible optoelectronic circuit simulation, analysis and optimization, as well as performance verification on application-specific system-level.
