The demand of bandwidth capacity has increased exponentially in recent years due to the rise of high-speed Internet. For low-cost Metropolitan Area Network (WAN), operating wavelength at 1.3 µm is chosen due to its low dispersive nature in the silica optical fibers, thus avoiding the need for costly dispersion compensators. Quantum dots (QDs), a self-assembly of coherently strained and defect-free three-dimensional nano-islands, are deemed as the new generation of active material. This is because one can expect better device performances due to the delta-like carrier density of states associa...
