"Probabilistic Shaping for PAM-8 Optical Ethernet Systems"

Abstract: A performance comparison of probabilistically shaped (PS) pulse amplitude modulation (PAM)-8 and uniform PAM-8 is performed in the context of 168 Gb/s intensity modulation and direct detect (IMDD) optical Ethernet system. PS-PAM-8 provides gain in terms of the optical signal-to-noise ratio of about 1.2 dB in the back-to-back system, and an increase of more than 15% in transmission reach at the 20% low-density parity-check (LDPC) soft decision forward error correction (FEC) threshold.

"Achievable mitigation of nonlinear phase noise through optimized blind carrier phase recovery"

Abstract: Partial mitigation of nonlinear phase noise by standard carrier phase recovery has been reported both, experimentally and through simulations. In this paper we quantify the achievable mitigation by using different implementations of the carrier phase recovery. All the approaches are based on the widespread blind phase search algorithm but follow different optimization strategies for handling simultaneously both, linear and nonlinear impairments of the channel. We apply the algorithms on probabilistically shaped signals transmitted over standard single mode fiber and non-zero dispersion shifted fiber in order to consider conditions in which the system performance is evidently affected by nonlinear phase noise. The results obtained are finally compared to the statistically estimated achievable phase noise removal. This allows to evaluate in different system scenarios an upper bound to the potential gain obtainable by algorithms developed to mitigate the detrimental impact of short-correlated nonlinear phase noise.

ePIXfab Design Course

June 2020

Learn about photonic circuit simulations starting from basic components and going up to complex PICs consisting of several passive/active (electro)optic elements. Get acquainted with the software tools by working on various application cases, different technology platforms, and layout-ready process design kits.
The training provides the standard knowledge for all researchers that want to design and simulate any photonic integrated circuit. It covers basics as well as more advanced software functionality making it very useful for new employees or graduate students, as well as experienced engineers in companies. Anyone who is active or interested in photonic integration and who needs a better understanding of designing or simulating PICs is welcome!
Attendees will learn by means of demonstrations and hands-on sessions how to seamlessly integrate and automate different steps of a typical design process. Modeling, optimization and layout extraction of basic building blocks and complex hierarchical circuits will be subject of the training.

OIDA Sponsored Webinar:

Migrating a PIC Simulation to a System Design: Silicon-Photonic Modulator in a PAM-4 Link

Modeling and simulation at both the circuit- and system-levels are critical in the design process for optical communication, quantum key distribution and sensing applications. Seamless migration between these two levels of abstraction will be demonstrated in VPIphotonics Design Suite.
This webinar will focus on an optical communication application example by modeling a silicon-photonic modulator at the circuit-level and implementing it for simulation at the system-level in a PAM-4 link.

May 2020


Internet traffic handled by datacenters is growing rapidly, fueling the need for deployment of new and improved communication equipment that relies heavily on optical interconnects. Optical interconnects are composed of optoelectronic devices that combine functionality in both electrical and optical domains. To address the growing need for optical interconnect design and optimization, we announce a new simulation workflow capability that seamlessly connects VPI Design Suite with PathWave Advanced Design System (ADS) from Keysight Technologies, enabling designers to predict the signal integrity of electrical-optical-electrical data links.
