Abstract: THz wireless links with carrier frequencies beyond the W band represent an attractive way to extend existing fiber-optic network infrastructure. Such system configurations are advantageous for broadband access networks in dense urban areas, ad hoc networks of large events, or applications where fiber cable deployment is impractical. The design of these hybrid networks requires special attention, as the THz wireless propagation characteristics are affected by weather and atmospheric effects influencing the signal performance dynamically.
We investigate within the collaborative project AI-NET-PROTECT alternatives for link architectures and analog interfaces to enable seamless interconnection between the optical fiber and the THz wireless extender of the hybrid links. We present statistical information about weather conditions to derive channel models for wireless transmission and analyze its impact on system performance. Additionally, we demonstrate the applicability of variable rate and spectral efficient modulation formats and the robustness of conventional DSP algorithms exclusively developed for optical fiber transmission when deployed to the combined fiber-optical/THz-wireless link.

Abstract: We present a versatile simulation framework for modeling, designing, and analyzing classical and quantum communication systems over terrestrial and satellite free-space optical links. It addresses different FSO use-cases in terrestrial, ground-to-satellite, satellite-to-ground, and inter-satellite links using direct- and coherent detection schemes. For the FSO channel modeling, we discuss two methods: an intensity-based method and a method that captures the wavefront of the optical beam using the phase screens technique. Additionally, we provide essential details about system-level simulations to analyze and optimize the entire link performance using mitigation techniques, DSP, and error correction methods.

• The function "Longitudinal Power Estimation" has been added to estimate the signal power profile in a distance-wise manner after propagating through a multi-span optical link. This in-situ monitor estimates the power profile along the link-longitudinal axis from its incoming signal by employing digital post-processing of coherent receiver data.
• The function "Nonlinear Predistortion Filter" has been updated to enable hyperparameter tuning via Bayesian optimization (BO). This allows us to autonomously optimize the memory tap distribution of Volterra series and adapt parameters used in the generation of a digital pre-distortion filter for optical transmitters.

Simulation of Classical & Quantum Communications over FSO Satellite Links
Free space optical (FSO) communication technology based on the optical signal transmission through a free-space channel has gained significant interest in recent years. FSO satellite links have the potential to establish a global all-optical communication network that could cope with the increasing demands for high data rates and communication capacity. Moreover, satellite-based quantum key distribution (QKD) could provide secure and private communication between distant users.
VPIphotonics Design Suite™ offers advanced means for simulation of both classical and quantum optical communication systems for terrestrial and satellite FSO links. In this webinar, we focus on modeling aspects of FSO signal transmission in ground-to-satellite, satellite-to-ground, and intersatellite links. We will also work through a few live demos of application examples and investigate the FSO system performance in presence of such adverse effects as atmospheric scintillation, attenuation, beam diffraction, and pointing errors. In addition, we discuss the satellite-based quantum key distribution and demonstrate how the performance of the QKD link depends on a satellite's position and other link parameters.

»"The Photonic Design Workflow" presented by Chris Maloney, 13th April 2022 at 10am ET
Abstract: One of the biggest challenges faced by photonic design and systems engineers is effectively utilizing the variety of software design tools needed to accomplish specific design or modelling studies. Depending on the scope of the design task, it is important to distinguish between levels of abstraction and provide more or less detail to sections of the simulation as needed. This could be accomplished by using photonic foundry PDK building blocks to model specific components within a full optical system or by providing a full optical system simulation as a building block to electronic design automation tools for full end-to-end link simulation. We will discuss a comprehensive photonic design workflow that integrates design and simulation techniques ranging from optical waveguides and fibers to full optical communication systems that is interoperable with a wide variety of 3rd party software solutions.

Abstract: The collaborative R&D project KIGLIS envisions artificial intelligence (AI) enabled fiber-optic communications for smart cities. It targets a considerable increase in data rates with almost identical hardware costs using AI methods. Dynamic bandwidth allocation and specific latency requirements will enable multiple access to passive optical networks (PON).
We present the performance limitations of different PON solutions based on direct-detection and coherent reception for up to 100 Gb/s and 31.5 dB power budget. We demonstrate effective electro-optical converted signal processing optimization using machine learning (ML) techniques. We show that sufficient receiver sensitivity and dispersion tolerance can be achieved by combining a low-chirp optical transmitter in the O-band and simplified receiver-side feed-forward equalization (EQ) in a PAM4 configuration. In C-band, ML-based-assisted EQ can reach the stringent power budget PON requirements when both coherent and direct-detected systems are employed.
Optical Link Design Automation from Access to Core Networks
Recent growth in the deployment of xHaul networks including metro and core networks triggers the application of very different technologies to support the increase in link distances and traffic. Critical network design constraints include dense wavelength division multiplexing (D)WDM of channels operating at different data rates, and the deployment of optical amplifiers and dispersion compensation modules (DCMs) to meet power and dispersion budget requirements. Cost-optimized planning of such networks is a challenging task considering the diverse equipment constraints. In this webinar we demonstrate an automated network design that efficiently addresses the challenges and requirements for various types of networks.

Abstract: We present an algorithmic approach that offers an efficient way of multiple lightpaths reconfiguration, either for increased traffic requests, or lightpath restoration. It permits the building of a feasible optical network design considering the available spectrum, traffic demand characteristics, network topology, equipment configurations, and engineering constraints. We show the employment of methods for calculating and provisioning multiple lightpaths. Our approach is flexible enough to accommodate optical network topologies of different types and sizes. The result is a lightpath configuration that is optimized for spectrum utilization and GSNR degradation.
Together with Siemens EDA, we continue improving the interface between VPIphotonics Design Suite, L-Edit, and S-Edit tools to provide a streamlined environment for optoelectronic and photonic integrated circuits and systems design.

Abstract: PIC fabrication tolerances are inevitable and strongly degrade device yield, unless their impact on overall performance characteristics is considered during the design process. We present a general-purpose schematic-driven design framework that provides easy access to statistical performance techniques. By introducing a novel method that allows for the identification of critical light paths and applying automated phase compensation inside the models, the analysis of fabrication tolerances on-wafer and between wafers is significantly simplified. We demonstrate its application in several PIC designs including complex photonics-based neural networks.

Abstract: Inevitable manufacturing tolerances strongly degrade the fabrication yield of photonic integrated circuits (PICs), unless their effect on overall performance characteristics is considered and mitigated during the design process. We present a general purpose schematic-driven design framework that provides easy access to statistical performance techniques such as sensitivity, corner and yield analysis. It supports the analysis of statistical parameter variations due to manufacturing tolerances on-waver and between wavers, and delivers valuable insights into the dependency of structural parameters on the overall PIC performance. We demonstrate its application on complex PIC designs comprising up to hundreds of photonic building blocks.
