Paper Abstract

We present a fabrication technique for creating high-quality structures of antimonide-based quantum dots (Sb-based QDs), which show long-wavelength emissions for fiber-optic communications. By using the Sb-based QDs as the active medium, we successfully demonstrated optical-emissions in the 1.3- and 1.5-μm wavebands from a long-wavelength vertical-cavity surface emitting laser (VCSEL) structure fabricated on a GaAs substrate. Additionally, we describe a growth technique for Sb-based QDs on a silicon wafer, which may become novel-materials for silicon photonics technology.
