ABSTRACT This review examines the growing field of amino acid crystals for nonlinear optoelectronic applications. Amino acids, as the building blocks of life, possess unique structural and electronic properties that make them promising candidates for various optoelectronic devices. This paper provides a comprehensive overview of recent advances in the growth, characterization, and applications of amino acid crystals in nonlinear optics. We discuss the fundamental principles of nonlinear optics, the structural features of amino acids that contribute to their nonlinear optical properties, and various crystal growth techniques. The review covers a wide range of amino acid crystals, including L-arginine phosphate, L-histidine tetrafluoroborate, L-threonine, and glycine derivatives. We analyze their linear and nonlinear optical properties, such as second harmonic generation efficiency, laser damage threshold, and transparency range. Additionally, we explore emerging applications in frequency conversion, electrooptic modulation, and terahertz generation. The review concludes with a discussion of current challenges and future prospects in this rapidly evolving field.
