Three mode Er3+ ring-doped fiber amplifier for mode-division multiplexed transmission.
نویسندگان
چکیده
We successfully fabricate three-mode erbium doped fiber with a confined Er(3+) doped ring structure and experimentally characterize the amplifier performance with a view to mode-division multiplexed (MDM) transmission. The differential modal gain was effectively mitigated by controlling the relative thickness of the ring-doped layer in the active fiber and pump launch conditions. A detailed study of the modal gain properties, amplifier performance in a MDM transmission system and inter-modal cross-gain modulation and associated transient effects is presented.

متن کاملMode-division multiplexed transmission with inline few-mode fiber amplifier.
We demonstrate mode-division multiplexed WDM transmission over 50-km of few-mode fiber using the fiber's LP01 and two degenerate LP11 modes. A few-mode EDFA is used to boost the power of the output signal before a few-mode coherent receiver. A 6×6 time-domain MIMO equalizer is used to recover the transmitted data. We also experimentally characterize the 50-km few-mode fiber and the few-mode EDFA.

Fiber-laser sensors have potential advantages over conventional fiber-optic interferometric sensors owing to their simplicity in both optical configuration and electronic signal processing." A fiber ring laser is a good candidate for rotation-rate sensing because of the same advantages, and such a fiber-ring-laser gyroscope was demonstrated by use of Brillouin gain in the fiber.4'5 The Brilloui...
متن کاملAll-optical mode-group multiplexed transmission over a graded-index ring-core fiber with single radial mode.
We present a design of graded-index ring-core fiber (GI-RCF) supporting 3 linearly polarized (LP) mode-groups (i.e. LP01, LP11 and LP21) with a single radial index of one for mode-division multiplexed (MDM) transmission. Reconfigurable spatial light modulator (SLM) based spatial (mode) (de)multiplexers are used to systematically characterize spatial/temporal modal properties of the GI-RCF. We a...

We demonstrate a stable and tunable single-longitudinal-mode SOA-EDF ring laser for high-speed data transmission systems. The laser is constructed by incorporating an SOA into the EDF ring cavity. The SOA acts as a saturable absorption high-pass filter to suppress cavity mode partition noise at low frequencies. Such design ensures a stable and single-frequency operation for more than several ho...
