In this review, we present a survey on the use of molecular nonlinear crystals in the context of terahertz (THz) photonics. The fundamentals of nonlinear optics for converting optical and infrared radiation into THz radiation with the basic theory of femtosecond optical rectification and difference frequency generation are described. Various types of phase-matching conditions that can be achieved in molecular crystals are discussed. It is shown that one of the unique features of molecular crystals is the ability to generate tunable narrowband terahertz radiation using femtosecond lasers. We also provide a detailed description of the most commonly used and promising molecular crystals such as DAST, DSTMS, OH1, HMQ-TMS, DCMBI, and GUHP. This review also presents a description of recent publications which show the prospects of using molecular nonlinear optical crystals in THz photonics.

“…The synthesized red salt material was collected and kept at constant temperature of 140°C in hot air oven for 2 hours to avoid the hydrate formation. [24] The collected dried red salt material is the pure DAST raw material. Then the product was refined by the successive recrystallization process and the methanol solvent was used to achieve the high purity of the material.…”

“…Recently, we have reported Zn-doped DAST crystals and achieved good SHG efficiency, which shows the excellent nonlinear optical properties of crystal. [24] On the basis of above reported result, we have to choose some inorganic metal ions as dopants such as MnCl 2 , CdCl 2 , and some metal sulfates. In this article, we have reported that pure and Mn-doped DAST (Mn 1: 0.01 mol%, Mn 3: 0.03 mol% and Mn 5: 0.05 mol%) dopants with DAST crystals were grown effectively by slow evaporation process and the structural features are experimentally investigated by the single crystal X-ray diffraction (SXRD), powder X-ray diffraction analysis (PXRD).…”

The intent is to explore the optoelectronic properties of metal ions doped stilbazolium derivative, 4-N,N′-dimethylamino-N-methyl-4-stilbazolium tosylate (MnCl 2 -DAST) nonlinear optical crystal materials for the existing technological necessities. The Mn-DAST single crystals are crystallized by adopting the slow evaporation solution technique (SEST). The structural and crystallographic dimensions of grown crystals are affirmed using single-crystal X-ray diffraction and powder crystal X-ray diffraction. Fourier transform infrared spectra are performed to explicate the functional groups and energy dispersive X-ray analysis (EDAX) spectra confirm the presence of the chemical elements of grown crystals. The UV-vis absorption spectra of DAST and Mn-DAST crystals exhibit all possible n-* and -* electronic transitions. The blue shift is observed in the doped materials due to the exchange of lone pair electrons between the metal ions and organic molecule. Tremendously, the second order harmonic generation (SHG) efficiency of Mn (0.01 mol%) doped DAST crystals has 1.68 times larger than that of DAST crystal. From the metal-organic crystals (Mn-DAST), all the results brought out are the promising materials in the design of nonlinear optical applications.

“…It was intensively investigated experimentally and predicted theoretically based on the discontinuities of the structure and the normal component of the electric field strength at the surface of the inorganic NWs that have diameters substantially below the wavelength of visible light. , On the basis of the above observation, the highly aligned assembly of the Se NW minimizes undesirable optical scattering and confines the efficiently guided spectral SHG emission, which is highly beneficial to carefully design a novel platform of SHG-based laser displays. Moreover, we believe that the nonlinear optical capability combined with the planar assembly process enables the development of high efficiency optoelectronic devices for other possible applications. − …”

The second-harmonic generation (SHG) phenomenon, which readily supports the characteristic advantages of promising laser-based display systems, brings a new concept to advanced displays. Here, we demonstrate a laser projection display that utilizes the fabrication and design principles in individual micron-scale pixel arrays by depositing colloidal Se nanowires, a nonlinear optical nanomaterial for full-color light emission. Our system reveals the manufacturing process of planar light-emitting elements without the use of complex color segments, and the layout represents a full-color laser display with high-resolution pixels extracted from the combination of a pulsed femtosecond laser scanning process to access the frequency up-conversion technique based on a wavelength-tunable manner. The work presents attractive features for newly emerging multifunctional optical components composed of unique nanomaterials that can be applied for displays, bioimaging, and other optoelectronic devices.
