Few-Mode TDFA for Mode Division Multiplexing at 2µm

2014 IEEE Photonics Society Summer Topical Meeting Series, 2014
We report the first demonstration of an inline two-mode group thulium-doped fiber amplifier (TMG-TDFA) operating at 2µm for mode-division multiplexed transmission. Similar gain and noise figure performance are obtained for both spatial modes under cladding-pumped operation.

Few-mode optical fiber for mode-division multiplexing

Optical Fiber Technology, 2011
Abstract This paper describes the group delay difference and mode coupling of few-mode fiber for “uncoupled” mode division multiplexing. Optical mode separation is compatible with few-mode fiber. It has complementary characteristics with the MIMO technique.

Few-mode fibers for mode division multiplexing transmission

SPIE Proceedings, 2012
A study is presented of the fiber properties needed to achieve 10-mode multiplexing transmission. A combination of MIMO processing with optical LP mode separation is proposed to prevent the need for massive MIMO computation. The impact of mode crosstalk, differential mode delay, and the mode dependent loss of the few-mode fibers on mode multiplexing

Equalizer complexity of mode-division multiplexed coherent receivers

2012 14th International Conference on Transparent Optical Networks (ICTON), 2012
We show that OFDM requires the lowest equalizer complexity for crosstalk compensation in a mode-division-multiplexing receiver. For a 2000-km transmission distance and less than 10% ODFM-specific overhead, the modal dispersion must be below 12 ps ...
