Popis:	The state of the art in the Czochralski growth of various optical-quality ferroelectric tungsten bronze single crystals is reviewed with respect to crystal structure, phase transitions and canonic makeup. Based on our growth of over 25 single crystal bronzes, we have classified these bronzes into four categories having distinctly different ferroelectric and electro-optic characteristics. Currently, tungsten bronze Sr0.6Ba0.4Nb2O6 (SBN:60) and Ba6-x Srx (Nb,Ti)10O30 (BSTN) single crystals with high electro-optic figures-of-metrit have been optimized in guided-wave optical structures, in which the performance is superior to that of LiNbOj and LiTaOj. We review the role of tungsten bronze materials for telecommunications, sensing and signal processing using these guided-wave structures.
