A broadband light source for a wavelength range of around 1.2-1.3 μm can be fabricated using a multi-stacked and modulated InAs/InGaAs quantum dot (QD) structure with the sandwich sub-nano separator (SSNS) technique. These techniques, such as use of the modulated QD structure and SSNS structure, are considered useful in obtaining a high-quality and ultra-broadband QD optical gain material for the laser and/or optical amplifier. A broadband (>75 nm bandwidth) and bright (few tenths of a mW) light emission in its waveband is successfully demonstrated from a QD laser diode using a modulated QD optical gain with the SSNS technique.
