Growth of Fiber Crystals for Infrared Optical Waveguides

Abstract

Modified floating zone technique is proposed to draw fiber single crystal for infrared optical waveguides. Using this technique, KRS-5 fiber single crystals with 0.6∼1 mm in diameter were prepared at the high growth rate of 0.5∼3 cm/min up to 2m in length. The fiber crystals have a circular cross-section and high plasticity to be bent freely at room temperature.
