Presenting the data! What is a quantum dot laser?

Presenting the data! What is a quantum dot laser?

Successfully identified the crystal growth conditions for high-density quantum dots to realize excellent quantum dot lasers and achieved practical application.

Our quantum dots are produced using the Molecular Beam Epitaxy (MBE) method. The MBE method is a technique that grows crystals on a substrate by evaporating elemental materials from a crucible in a growth chamber maintained at ultra-high vacuum. Through years of accumulated research and development, we have deepened our understanding of crystal growth physics, allowing us to identify the crystal growth conditions for high-density quantum dots that enable the realization of excellent quantum dot lasers from various combinations of growth conditions such as growth rate and substrate temperature, successfully achieving practical application. 【Features】 ■ Stable operation in high-temperature environments and high reliability ■ Excellent return light resistance *For more details, please refer to the PDF document or feel free to contact us.
