Abstract

Single-crystal sapphire fibers have been grown, using the laser heated pedestal technique, with losses as low as 0.7 dB/m and with lengths up to 150 cm. We have applied polymer and sol- gel coatings to the fibers and we have evaluated the performance of these coatings as optical cladding. The best coating seems to be teflon AF even though the coatings are reasonably thin and low temperature.
