VPIphotonics announces new machine learning framework to design and implement deep neural networks for optical communication systems and photonic devices.
VPItoolkit ML Framework is a versatile add-on to any of the simulation tools of VPIphotonics Design Suite,
enabling the implementation and design of deep neural networks (DNN) for various applications, such as equalization and nonlinearity mitigation for optical
systems, device characterization, evaluation and inverse design of photonic devices.
This powerful framework provides an open-source Python-based DNN with an intuitive easy-to-use interface to manipulate model parameters and convergence
constraints. Additionally, it allows for easy deployment of custom-made machine learning (ML) algorithms by the user.
As the IEEE Photonics Society's flagship meeting from 13-17 November 2022 in Vancouver, Canada, the IEEE Photonics Conference's topics cover vast technical areas within the photonics community and the interests of our members. Attendees will be able to participate in Plenary Sessions, Invited Talks, Panel Discussions, Tutorial Sessions, Workshops, Special Symposia and the Industry Day programming, across the conference's topical areas.
It is our pleasure to meet you personally and to discuss your simulation requirements!
VPIphotonics announces the release of version 5.2 of the VPItoolkit DSP Library, a powerful set of digital signal processing algorithms developed by the Photonic Networks and Systems department at Fraunhofer HHI.
• 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.

From Waveguides to Optical Transmission Systems – A Comprehensive Training Series (Summer 2022)
29 August - 9 September 2022, online
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.

VPIphotonics at Optica Technology Showcase
13 - 14 April 2022
»"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.

Data Centres / PONs: "AI-enabled fibre-optic access networks for smart cities"
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.

Paper 12027-5: "Transmission-aware multiple lightpath reconfiguration in flexgrid optical 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.

Title: "Fabrication tolerance-aware schematic-driven PIC 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.
