摘要: 铁电晶体光纤将铁电材料优异的光学非线性、电光效应和压电性与光纤波导的结构优势相结合,是集成光子学领域的前沿研究方向。本文系统梳理了铁电单晶光纤与铁电微晶光纤的制备技术、材料体系、性能特性与应用进展。在制备技术方面,激光加热基座(LHPG)法和微下拉(μ-PD)法可实现高质量单晶光纤的生长,原位析晶法和低温复合法为微晶复合光纤的制备提供了可规模化生产的通用方法。在材料体系方面,铌酸锂、钽酸锂和弛豫铁电单晶代表了铁电单晶光纤的主流方向,而铁电微晶光纤则通过原位析晶或低温复合将铁电微晶嵌入玻璃基质中,赋予光纤二阶非线性功能。在非线性光学应用上,周期极化铁电单晶光纤可实现高效率准相位匹配二次谐波产生,而随机分布的铁电微晶光纤得益于随机准相位匹配机制,呈现出宽带、偏振鲁棒的频率转换特性。此外,铁电晶体光纤在非线性频率转换、电光调制及能量收集等领域也展现出广阔的应用前景。本文最后讨论了该领域面临的关键科学问题与挑战,并对未来发展方向进行了展望。

Abstract: Ferroelectric crystal fibers combine the excellent optical nonlinearity, electro-optic effect, and piezoelectric property of ferroelectric materials with the structural advantages of fiber waveguides, which is a cutting-edge research direction in the field of integrated photonics. In this paper, the preparation techniques, material systems, performance characteristics, and application progress of ferroelectric single-crystal fibers and ferroelectric microcrystalline fibers are systematically reviewed. In terms of preparation techniques, laser-heated pedestal growth (LHPG) and micro-pulling-down (μ-PD) methods can realize the growth of high-quality single-crystal fibers, while in-situ crystallization and low-temperature composition methods provide a general method for large-scale production of microcrystalline composite fibers. Regarding material systems, lithium niobate, lithium tantalate, and relaxor ferroelectric single-crystals represent the mainstream directions for ferroelectric single-crystal fibers. Ferroelectric microcrystalline fibers, on the other hand, embed ferroelectric microcrystals into a glass matrix via in-situ crystallization or low-temperature composition, thereby endowing the fibers with second-order nonlinear optical functionality. In nonlinear optical applications, periodically poled ferroelectric single-crystal fibers can achieve high-efficiency quasi-phase-matching second-harmonic generation. Randomly distributed ferroelectric microcrystalline fibers, benefiting from random quasi-phase-matching mechanisms, exhibit broadband and polarization-robust frequency conversion characteristics. Additionally, ferroelectric crystal fibers also show broad application prospects in nonlinear frequency conversion, electro-optic modulation, energy harvesting, and other fields. Finally, this paper discusses the key scientific issues and challenges in this field and provides an outlook on future development directions.

Key words: ferroelectric crystal fiber; phase matching; second-order nonlinear; electro-optic modulation; energy harvesting
