Talks to be presented:

Optics to Scale the Datacenter Network
Ryohei Urata, Google, USA; Hong Liu, Google, USA
Monday, 7 June; 11:00 - 11:30 PDT

Over the past decade, datacenters have rapidly grown as an enabler of new applications and capabilities (cloud computing, machine learning, internet content streaming, internet search, social networking, etc.). As such, datacenter networks have become the singular force driving the business and technology development of corresponding fiber optic communications. In this presentation, we will review the evolution of this network and corresponding optical interconnect technology over the past decade, as well as a roadmap and trends for the next 3 to 4 years.

Fiber Communication Networks - Telecom vs. Datacom
Cedric F. Lam, Google, USA; Shuang Yin, Google, USA
Monday, 7 June; 12:00 - 12:30 PDT

This tech talk will provide an overview of fiber communication networks for telecom and datacom. We will compare and contrast the differences between these two application spaces in terms of key drivers, requirements, technology evolution and design philosophies. We try to shed some light on the directions for future R&D.

High-Speed Semiconductor Lasers and Modulators for Data Communications
John Bowers, Univ. of California at Santa Barbara, USA
Monday, 7 June; 14:00 - 14:30 PDT

Amplitude and phase modulation of light for transmission at 10, 40 and 100 Gbit/s and beyond are a critical problem for fiber-optic networks. We will review the basic concepts of high speed laser modulation and high speed optical modulators. The fundamental physics and design of modulators will be reviewed. The microwave characteristics of semiconductor lasers, important for high-speed digital and analog applications, are presented. Methods to increase the bandwidth are illustrated with examples from literature, along with results showing the current state of the art.

50G-PON: The Latest ITU PON System
Yuanqiu Luo, Futurewei, USA
Tuesday, 8 June; 11:00 - 11:30 PDT

This talk introduces passive optical network (PON) technologies and applications in the optical broadband access areas. It focuses on the latest ITU PON system, 50G-PON. The 50G-PON system is specified by the ITU G.9804 series of recommendations. This talk reviews major features of 50G-PON in both physical and protocol layers. Future research and development work are discussed to drive this solution.

Lessons Learned in Data Transmission and Processing in Optical Communication Systems
​Alan Wilner, Univ. of Southern California, USA
Tuesday, 8 June; 12:00 - 12:30 PDT

The transmission and processing of data in optical communication systems has experienced astounding success and growth. Although there have been many technological advances, there were also many lessons learned as far as what issues can derail the deployment of certain technologies. This presentation will describe some R&D perspectives in terms of concerns and hurdles, with highlights involving capacity growth using multiplexing schemes, performance and functionality enhancement through signal processing, and directionally and bandwidth in free-space links.

LIDAR, Boom or Bust?
Martin Zirnginbl, II-VI Incorporated, USA; Cibby Pulikkaseril, Baraja, Australia
Wednesday, 9 June; 11:00 - 11:30 PDT

Special Purpose Acquisition Companies (SPAC) are investing billions of dollars in a variety of autonomous LIDAR companies despite the fact that there is no significant LIDAR revenue as of today. We will discuss the technical and application hurdles that must be overcome in order for LIDAR to become a business generating meaningful revenue and profits.

Silicon Photonic Circuit Design
Wim Bogaerts, Univ. of Ghent, Belgium
Wednesday, 9 June; 12:00 - 12:30 PDT

In the past decade, photonic chip design has slowly evolved from physical electromagnetic simulations to higher-level circuit design. The procedures, tools and methods closely resemble those of electronic design automation (EDA), which is useful, as photonic-electronic codesign becomes more and more important to realize complex photonic functions. But the differences between photonics and electronics also introduces quite some challenges, especially in fast and accurate photonic circuit simulation and assessing the effects of fabrication variations on the yield of the circuits. In particular, silicon photonics technology is exceptionally sensitive to nanometer-scale deviations. We will discuss the current state of photonic circuit design, and the challenges lying ahead to make photonic design as reliable as its counterpart for electronics.

How I Use Python to Automate My Experiments
Nicolas Fontaine, Nokia Bell Labs, USA
Wednesday, 9 June; 15:00 - 15:30 PDT

In this tech talk, we will show how to align a mode multiplexer in an optical laboratory. A bunch of open source software is used, including python, to automate positioning stages, data acquisition, and result processing.

Optical Fiber Sensors Commercialization: Present Status and Future Opportunities and Trends
Alexis Mendez, MCH Engineering, USA
Thursday, 10 June; 11:00 - 11:30 PDT

Over the past three decades, fiber optic sensors (FOS) have made a complete transition from basic lab prototypes to successful commercial products.  Their commercialization has been slow-moving and rocky at times, but always progressive, innovative and dotted with multiple successful companies, products and solutions along its path.  And, although the Covid19 crisis presents some challenges in the short term, the future outlook remains bright, with steady growth and new opportunities in biomedical, industrial, aerospace and environmental monitoring applications.  This tech-talk will do a brief overview of the present FOS market, its trends and future outlook.

Silicon-photonic-based Short-reach Pluggables
Christopher Doerr, Doerr Consulting, LLC, USA
Thursday, 10 June; 12:00 - 12:30 PDT

We will discuss silicon-photonic based pluggable transceivers for interconnects below 40 km. We will discuss both coherent and direct detect types and where they are likely to play significant roles in the next 5-10 years.

Optical System Innovations in DCI Transport Networks
Lukas Chrostowski, Univ. of British Columbia, Canada
Friday, 11 June: 12:30 - 13:00 PDT

We review the most important WDM system innovations motivated by the evolution of DCI transport. State-of-the-art coherent transmission has already exceeded 6 b/s/Hz in transatlantic deployments. Moreover, the adoption of software innovations in automation and programmability, which DCI pioneered in transport networks, has also simplified operations and enables the emergence of open transport architectures. Combining these advances with emerging network analytic frameworks allows exciting innovations in network design and management optimization.
