Abstract:

A new technique for producing radial gradient refractive index r-GRIN titanium-doped silica lenses has been developed employing a sol-gel leaching method. The obtained lenses possess a parabolic index distribution and give good images with high resolution. They also show high coupling efficiency with optical fibers and enable a low-loss large distance space transmission of light between optical fibers. Furthermore the sol-gel r-GRIN lenses show a high degree of environmental stability as expected for the doped-silica lenses.
