Abstract: Conventional core/clad optical fibers composed of all-solid silica material were fabricated using the "stack and draw" technique. The optical fiber consists of Ge-doped silica glass in the core and un-doped silica glass in the clad. The optical attenuation and the chromatic dispersion spectra of these optical fibers, with their external diameters of 212, 176, 150 and 125 μm, were characterized by using a PK2500 and a PK2800 instrument respectively. The attenuation of these optical fibers, at 1550 nm, was approximately 5 dB/km and the zero-dispersion-wavelength range from 1350 to 1370 nm. On the other hand, bend loss spectra of these fibers were characterized by using small bend diameter rods (bend diameters from 2.5 to 10 mm). The bend loss spectra show that these all-solid optical fibers are almost insensitive to bend effect. In addition we explore the nonlinear properties of these fibers to investigate the potential for supercontinuum generation. © 2012 SPIE.
