Translated from French
Synthesis of silica preforms by modified chemical vapor deposition (MCVD), doped for index control (Ge, P, Al) or for active fibers (Er, Yb, Nd and other rare earths).

Our MCVD laboratory features two SG Controls glass lathes. One synthesizes silica preforms and includes a chemical doping and etching station. A Chelate vapor-phase deposition and in situ doping unit achieves higher dopant concentrations that are more evenly distributed in the glass than with solution doping.
COPL hosts the first university laboratory in Canada to manufacture glass preforms and optical fibers. Our preforms are then processed on our fiber drawing towers.
