AB This work introduces a new approach to prepare active GRadient-INdex (GRIN) materials by gradually doping commercial silica cylindrical substrates with different optically active ions or materials by the Laser Zone Melting (LZM) process. Scanning Electron Microscopy (SEM) combined with energy dispersive X-ray (EDX) analysis demonstrate that the dopants are gradually incorporated into the cylindrical substrate under controlled penetration depths. This simple, environmentally respectful fabrication method opens the possibility to manufacture versatile GRIN optical elements on a large scale and reduced cost.
