  • Description

    The transmission capacity required by modern fiber-optic communication systems often significantly exceeds the capacity of a single single-mode fiber, therefore requiring new cost-effective fibers and components to support massive parallel optical paths (space-division multiplexing).

    Additionally, traditional wavelength-division multiplexing (WDM) based network architectures scale poorly for large numbers of spatial paths and new scalable and cost-effective network architectures are required.

    In the first part of short course, we will address various options to implement massive parallel optical fibers links by using various fiber type including commercially available fiber ribbons, multicore fibers and multimode fibers, and discuss the advantages of using parallel optical links regarding transmission capacity and power efficiency.

    In the second part we will address optical amplification schemes that support multiple parallel channels like amplifier arrays or cladding pumped fibers amplifiers and related trade-off between the amplification bandwidth, power efficiency, and number of parallel channels, that has recently significantly impacted the design of submarine transmission systems.

    The third part of the course will address basic optical switching technologies adapted to support multiple spatial paths and present possible related ultra-high capacity network architectures and address the implications on scalability, network management, and integration with existing WDM systems.

    Additionally, the short course will also address more forward-looking SDM technologies like mode-division multiplexing in multimode and coupled-core fibers based on coherent multiple-input-multiple-output (MIMO) digital signal processing, quasi-single-mode transmission, mode-group-division multiplexing, and general transmission over channels with crosstalk.

  • Instructor Bio

    Dr. Roland Ryf is the director of the Photonic Subsystems Research department at Nokia Bell Labs, Murray Hill, NJ, where he is working on photonic technologies for switching, filtering, and amplification in space-division multiplexed optical communication systems. In particular, he has performed numerous record-breaking long distance transmission experiments in multimode and multicore fibers based on multiple-input multiple-output (MIMO) digital signal processing techniques.
