Advances in Nonlinear Optical Materials: Theory and Experiment

About this Research Topic

Nonlinear optics and its impact on science and technology are highly acknowledged by scientists and have brought many Nobel prizes in chemistry and physics. Nonlinear optics find extensive applications in different aspects of life. The main approaches include second harmonic generation (SHG), telecommunications, signal processing, data storage, medical analytical tools based on optics and sensors. The most considerable advantages of optics over electronics are the fast speed of operations in optical computing and photonic switching. Nonlinear optical (NLO) process is observed at wavelengths from near infrared to deep ultra-violet region of spectrum through nonlinear material mediums. To date, experimentalists and theoreticians have outlined various promising materials to possess exceptional NLO properties such as inorganic fullerenes, donor- bridge-acceptor systems, and chiral conjugated molecules. Lately, inorganic octupolar molecules, NLO crystals, polymers, carbon dots, graphidyne nano-sheets, multi-decker sandwich clusters are introduced as promising NLO materials. Furthermore, design of high performance nonlinear optical materials both theoretically and experimentally is the dire need in the field of nonlinear optics. 


The broad technological applications of nonlinear optical process are the main impulse behind the hunt for mediums with outstanding NLO characteristics. The ideal nonlinear optical materials must meet the requirements of being chemically stable, cost effective, and exhibiting a high nonlinear optical response. At present, various strategies have been reported by both experimental and theoretical studies. These techniques include substitution effect, doping, extensive π conjugation, electron push–pull mechanism, utilization of bond length alteration theory (BLAT), and introduction of electron acceptor/donor group. There is still a need to explore and propose most favourable theoretical as well as experimental methods to fabricate high performance NLO materials.
