30Gbit/s 3 × 3 Optical Mode Group Division Multiplexing System with Mode-Selective Spatial Filtering
Fiber optics communication Multiplexing
2015/5/25
A 30Gbit/s 3 × 3 optical Mode Group Division Multiplexing system with Mode-Selective Spatial Filtering (MSSF) using single-mode fiber is demonstrated over 20m graded-index multimode fiber. Crosstalk a...
Filtering Tolerance of 108-Gb/s PolMux Quadrature Duobinary Signal on 25-GHz Grid
Filtering Tolerance PolMux Quadrature Duobinary Signa
2015/5/20
We demonstrate the error-free transmission of 108-Gb/s PolMux quadrature duobinary signal in a 25-GHz spaced WDM system and investigate its tolerance to narrow optical filtering.
Tunable and variable clock generation up to 1.2 THz by filtering an actively mode-locked 42.5 GHz Quantum Dash Fabry-Perot laser with a reconfigurable filter
Optical communications Quantum dot devices
2015/6/10
We report on the generation of an optical clock up to 1.2 THz using a Quantum Dash mode-locked laser and a spectral filter, selecting two or three lines, which are separated by the desired spacing.
Coherent CD Equalization for 111Gbps DP-QPSK with One Sample per Symbol Based on Anti-Aliasing Filtering and MLSE
Fiber optics communications Coherent communications
2015/6/9
W e propose a coherent detection scheme with one sample per symbol. MLSE is used to compensate for ISI introduced by anti aliasing filtering. 50,000 ps/nm of CD is fully compensated with only 1 dB pen...
Polarization Insensitive All-Optical Retiming Based on Cross-Phase Modulation and Offset Filtering with Distributed Raman Amplification
Polarization Insensitive All-Optical Retiming Based Cross-Phase Modulation Offset Filtering Distributed Raman Amplification
2015/7/31
Adding distributed Raman amplification to a polarization insensitive all-optical retiming technique based on cross-phase modulation and offset filtering reduces the timing jitter of 10 Gb/s retimed si...
