Special Symposium on Space Division Multiplexing Technologies

Space division multiplexing (SDM) is seen as a promising solution to overcome the capacity limit of the single-mode fibers (SMF). Intensive research in this field over the past decade has brought forth sophisticated multi-core fiber designs and multi-mode transmission techniques constantly pushing the limits on achievable data rates and spectral efficiency with regard to a single strand of fiber. At the same time, efforts towards bringing SDM closer to an adoption in real systems also reveal the need for compatibility with standards developed for conventional SMF systems. In this sense, the task of drafting a roadmap towards commercialization is not straightforward and presents us with many options to choose from. Now is the time to discuss and think more carefully about these options. This workshop will try to foster a better understanding on how to bring the most advanced achievements in SDM research in line with commercial viability.

Special Symposium on Integrated Photonics and Information Security

The speed and information capacity of light waves provide potential benefits for information security devices and systems. In this symposium, we would like to highlight work in the area of optics for information security, in particular, the integration of such tools into on-chip photonic devices.
