Key Features

Uniformity: the VAD process achieves high-quality deposition, forming uniform optical fiber preforms and reducing defects. Controllability: material composition and deposition rate can be precisely controlled to adjust the optical properties of the resulting fiber. High purity: because the gaseous compounds used can decompose at high temperatures, VAD technology can generally produce high-purity silicon or germanium materials.
