Beyond Ultra-wideband Optical Communications

This diverse and interactive workshop (in-person only) addresses the hurdles of transmission bandwidth limitations in optical communication systems, exploring solutions of broadening the bandwidth and increasing data capacity from various perspectives including device manufacturer and subsystem developer (e.g., II-VI), full system provider (e.g., Nokia), and research institutes (e.g., NIT, ORC, AiPT).

Through keynote talks, interactive sharing sessions and networking opportunities, the workshop will benefit the professional development of PhD students, early career researchers and practitioners, create a two-way flow of knowledge transfer, and provide an excellent platform to explore the application of Aston technology.

We organise this event in the frame of celebrating the International Day of Light 2022.


Registration required. This workshop is on-site only and free, with limited places available at Conference Aston, Aston University.

Registration deadline for in-person attendance is 12 May 2022.

Venue: Conference Room 1, Conference Aston, Aston University, Aston Triangle, Birmingham, B4 7ET
