光エレクトロニクス用単結晶材料の育成と物性

抄録

Single crystal materials currently in use in various fields of opto-electronics are reviewed from a view-point of materials science. Characteristics of crystalline laser host, nonlinear optic crystals, electrooptic crystals, and ultrasonic light diffraction solid medium are described. Present state-of-the-art of the crystal growth by pulling method are discussed, and relations between the growth conditions and the deflects in the obtained crystals are stressed. Necessary steps in the process of the device fabrication are analysed, and some important factors such as phase diagram information, domain structure in oxide ferroelectrics, and laser damage susceptibility are pointed out. Some theoretical treatments of the oxide ferroelectric crystals useful for materials scientists are reviewed.
