Challenges and Opportunities in Optical Communications
by Professor Rongqing Hui, EE&CS, the University of Kansas, Lawrence Kansas
Challenges
- 1. Motivation of university research(focus on academics or compete with industry)
- 2. Require revolutionary ideas to push the envelop(how not to be incremental)
- 3. Motivation of going to higher data rates(application)
- 4. Diversified services and traffic patterns
- 5. Bottle necks in aggregation and access
- 6. Self consistent, plug-&-play optical networking
- 7. How to reduce the cost and energy consumption(especially in metro, access and data centers)
- 8. Require enabling photonics devices to more back from electronics dominated DSP to photonics
Opportunities
- 1. Ride on the wave of CMOS technologies: enabling high speed DSP in electronics domain
- 2. Coherent technology with high quality tunable lasers
- 3. Advanced modulation formats utilizing high speed DSP
- 4. 40G, 100G, 400G per wavelength, and beyond
- 5. Elastic bandwidth optical networking
- 6. New applications and services (Data centers, 3D, HD and holographic video, U-tubs, medical, tele-presence, work from home…)
- 7. Silicon photonics and large scale photonics integration
- 8. Improved capability of nano fabrication
- 9. Very large scale photonics integration(VLSPI): Parallelism and massive redundancy
