In the late 1980s, it was proposed that an optical wave system in which the refractive index profile is random in the transverse plane but is invariant in the longitudinal direction supported the transverse localization of light. The transport of optical images using transverse localization of light and its potential applications in biological and medical imaging were demonstrated by using a polymer optical fiber. In this work, an all-solid tellurite optical rod with a disordered transverse refractive index profile was first fabricated to study the transverse localization of light. The experimental results showed that after a CW probe beam propagated in our 5-cm-long fabricated tellurite optical rod, the beam became localized. With the potential of tellurite glasses such as high nonlinearity, broad transmission window and the control of the refractive index difference, the performance of image transport through a tellurite disordered optical medium by transverse localization of light is expected to improve in the near future.
