We show that forced coherent population oscillations (CPO) constitute an alternative set-up to conceive a controllable RF phase shifter, and that wave-mixing in SOAs opens the possibility to conceive optical tunable delay lines beyond the carrier lifetime limit.
We have calculated the band structure of 1.55μm InGaAsP/InGaAsP multi-quantum-well structures using Lüttinger–Kohn Hamiltonian taking into account the strain in the quantum wells (QWs) and barriers, and the confinement in the quantum wells. Using the calculated dispersion curves and oscillator strength between the different interband transitions, we have determined the optical gain in TE and TM mode...
A new architecture for low-cost WDM-PON is proposed, which combines a multi-wavelength CW source with a reflective SOA at 2.5 Gbps, with an optical budget up to 20 dB.
A selective area growth model was used to engineer a remote amplified modulator with an AlGaInAs multi-quantum well active layer. The selective mask layout was designed to fulfill special component requirements including +35 nm SOA gap detuning and low polarization dependence. The fabricated reflective device exhibits 10 dB maximum insertion gain and operates at 10 Gbit/s over 80 nm spectral range.
A new modular SOA-based integrated interferometer is presented: 40 Gb/s standard mode wavelength conversion is performed on the C-band with the 2-SOA's device, while 8 dB input power dynamic range is shown with the 4-SOA's version
