As genetically-encoded fluorescence indicators of calcium and membrane potential evolve and improve, optical methods advance to exploit their full potential for neurophysiology research. With so many choices, the neurophysiologist needs a systematic framework for comparing and predicting the performance of indicator/imaging system combinations. Dr. Foust will present such a framework for which the key figure of merit is the signal-to-noise ratio of the time-varying fluorescence signal. In this context I will also describe our efforts to boost photon budgets for membrane potential and calcium imaging with multi-focal two-photon and light-field imaging systems.

As the complexity of Photonic Integrated Circuits (PICs) continues to grow, testing environments become more complicated. In this webinar, we will present several simulation testbenches prepared for visualizing typical measurement characteristics. The examples we will discuss include methods for group index verification, simulation of passive circuit transfer functions, characterization of SOAs, and evaluating the transfer characteristic of an Activation Unit for a Photonic Neural Network. These examples will all be demonstrated live using the photonic design automation (PDA) software VPIcomponentMaker Photonic Circuits.

This presentation will go over the various techniques used to measure the optical performance of the grism component of the Wide Field Instrument on board the Roman Space Telescope.
23 February 2021, 3:00 PM - 4:30 PM
The benefits of systems engineering are widely promoted with varying degrees of understanding. This
webinar is based on many years of experience designing and building complex systems incorporating all of the engineering disciplines (optics, mechanics, electronics, and software). For me, understanding and
using systems engineering has been a natural approach driven by my instincts (even before it was a newfound contemporary “thing”).
Systems engineering is about balance and perspective. The word “system” conveys the inherently multidisciplinary nature of the work. The engineering work is fundamentally to hold a perspective that makes sure nothing is overlooked that could affect the outcome and to make sure that the best balance is achieved between all of the competing needs and wants that drive the creation of the system in the first
Systems engineering starts with requirements, and then systems engineering follows on to serve and protect the requirements by constantly evaluating error budgets and the compliance of the system with the requirements as the system is designed and built.
In this webinar you will learn by example:
- How to approach the development of requirements that satisfies your stakeholders
- How to use one sentence definitions to clarify ideas and gain consensus
- How to define and manage expectations
- How to gain and confirm requirements “completeness”.
03 February 2021, 2:00 PM - 3:30 PM
In this talk, Dr. Benjamin Lee will review the progress over the past ten years in developing a photonic switch solution that can potentially be manufactured and assembled with low cost, while offering fast reconfigurability and high performance.

Menlo Systems’ ultra-low noise (ULN) frequency comb technology, combined with advanced CW laser sources, ensures transferring the spectral purity of a superior optical reference to all CW lasers locked to the comb. This feature is exploited in clock comparisons or quantum experiments, where a long coherence time of the laser sources is mandatory.
26 January 2021, 11:00 AM - 12:00 PM
Within two decades, the optical frequency comb has revolutionized numerous fields in physics: Precision spectroscopy, time and length-metrology, molecular fingerprinting, and ultra-low phase noise microwaves mark just a few application examples. Being the only device with the ability to directly link the optical with the radio frequency domain, the frequency comb has become an irreplaceable tool, and not only for quantum optics laboratories.
20 January 2021, 11:00 AM - 12:00 PM
The next VIAVI webinar in our ongoing coherent optical module test series will focus on the transition into manufacturing. Today, end customer pricing expectations are more aggressive than ever. Long-term pricing is expected from day one. But finding a window during the product lifecycle to refine test processes is less and less practical after launch. This simple fact means test engineers must be thinking about manufacturing challenges from the very early stages of NPI.

Future wireless networks have to deal with a high degree of heterogeneity in terms of device classes, deployment environments, and mobility levels. Coexisting wireless technologies is an encouraging approach to revolutionize future networks. The radio-frequency (RF) based WiFi access points have been already considered to enable indoor traffic off-loading from LTE-cells. In addition to RF, optical wireless technologies such as visible light communications (VLC) open up a new opportunity. VLC is an emerging technology that uses, for example, the existing indoor lighting infrastructure to offer data transmission combined with high-quality illumination. The technology has the potential to add capacity and to be an attractive complementary to off-load data from existing RF networks. In this webinar, we focus on describing the potential of VLC, highlighting different research challenges, and articulating classical as well as machine learning-based approaches to deal with these challenges.

Streamlining the design process, shortening the development cycle, and reducing the transition to manufacturing remain some of the most demanding requirements for photonic integrated circuit (PIC) designers. During this webinar, Infinera and VPIphotonics will present a design and fabrication workflow for InP PICs developed to address these needs. The workflow is based on the Infinera Process Design Kit (PDK), which includes devices optimized to ensure the best performance and yield within Infinera’s InP foundry. VPIphotonics and Infinera collaborated to develop compact models for these PDK building blocks to allow for rapid prototyping of application-specific PICs.
Join our webinar to learn how to start your PIC design with a graphical circuit representation and system simulation in VPIphotonics’ software environment and smoothly proceed with physical layout implementation, verification, and fabrication by Infinera’s InP foundry.
