3 March, 1:00 PM - 3:30 PM     
It is commonly recognized that Si-photonics has evolved from being a research subject to a real fabrication platform. Although some Si-based transceivers are already commercialized, discussions still continue on whether the platform is competitive in other application areas which are still dominated by other technologies. 

This workshop aims to discuss how well the silicon photonics platform can penetrate into various areas of optical communications. It will be held in the form of team competitions in which a silicon photonics team will be opposed by an alternative technology team, making the case for III-V, dielectric waveguide, or free-space/micro optics to realize the same target devices:

 

  • Transceivers
  • Optical filters
  • Optical switches

Next-Generation Coherent Architectures – Pluggable vs Multi-haul, a Knockout or a Draw?
3 March, 1:30 PM - 2:30 PM     
Coherent architectures have trended toward increasing adoption of pluggable modules but margin stacking is creating competitive pressure, particularly in higher growth, edge coherent applications. Meanwhile, the latest generation of high-speed optics and DSPs with flexible transmission capabilities are offering solutions that support multi-haul applications ranging from high capacity edge DCI to submarine but fear of vendor lock-in concerns webscale providers. Panelists will discuss the synergies and trade-offs between these architectures and consider how they may evolve in future generations.


Workshop - Which One Will Succeed in Data Center Applications, Multi-chip or Monolithic Integrated Optoelectronic Chip?
3 March, 4:00 PM - 6:30 PM     
Coherent DSP chips will soon be able to process 100-Gbaud signals. Switch ASICs capacity is scaling to tens of Terabit with a channel rate >100 Gb/s. Proximity integration of DSP/ASIC chips and optical chips are highly demanded in these high-speed and high-capacity applications. On-board optics and optics in packaging with ICs are expected to address this challenge. Silicon photonic technology allows monolithic integration of analog/digital ICs with photonic circuits. However, 2.5D and 3D integration approach based on multiple chips or separate IC and PICs is another feasible technique. This workshop will emphasize on how to integrate photonic chips with electronic ICs for very high baud rate and large capacity. Pros and cons for monolithic or multi-chip integration approaches will be discussed. Advanced packaging techniques such as optics in packaging and on-board optics will be also focused.


Panel - PIC Foundry Commercial Access: Prospects and Challenges
6 March, 8:00 AM - 10:00 AM     

The generic foundry approach leads to a revolution in micro and nanophotonics, just as it did in microelectronics thirty years ago. Generic integration leads to a drastic reduction in the entry costs for developing Photonic Integrated Circuits. Integrated circuits using  generic integration open up a whole new range of applications including data communications, fiber-to-the-home, fiber sensors, gas sensing, medical diagnostics, metrology and consumer photonics. Present prospects and challenges of Silicon and InP-based photonic foundry technology are being addressed.
