Regenerative Amplification in a Quantum Dot SOA
All-optical devices Quantum dot devices Semiconductor optical amplifiers
2010/6/8
We report regenerative amplification of 10, 40 and 80 Gb/s return-to-zero (RZ) signals in a columnar quantum dot SOA (CQD-SOA). Self-phase-modulation (SPM) with a red-shifted band-pass filter and limi...
160 Gb/s Cross Gain Modulation in Quantum Dot SOA at 1550 nm
Cross Gain Modulation Quantum Dot SOA
2009/7/20
We report, for the first time, pattern-effect free wavelength conversion in a QD-SOA at 160 Gb/s in C-band. Very fast (10ps) 85% gain recovery and the use of a slightly detuned blue-shifted filter all...
