“…The next step will be to extend the present investigations for the study of the nonlinear properties of the organic molecules by borrowing the idea from semiconductor materials discussed in the present manuscript. The off-resonant (degenerate), free space optics and Mach-Zehnder interferometer based all-optical switching configurations are already demonstrated by many researchers to test various semiconductor and non-linear organic materials (Sharma et al, 2021). The next challenge is to check the semiconductor and organic materials for realistic applications using a silicon organic hybrid waveguide (Pattanaik et al, 2016).…”

“…The next challenge is to check the semiconductor and organic materials for realistic applications using a silicon organic hybrid waveguide (Pattanaik et al, 2016). The future road map is to incorporate organic and semiconductor materials in slot waveguide geometry (Sharma et al, 2021). It is to be noted that the figure-of-merit value of about ≥1 is reasonable for the switching applications; however, it is reported that the theoretical estimate of figure-of-merit of the YZ-V-69 organic molecule has attained a value ≥400 (Nalwa, 1993;Marder, 2016).…”

Optical non-linearities play a crucial role in enabling efficient and ultrafast switching applications that are essential for next-generation photonic devices. ZnS phosphor material produces the best results in terms of increased luminescence quantum yield when doped with certain impurities. Nevertheless, the investigation of the third-order non-linear optical susceptibility of the phosphor materials can be exploited for various switching applications. In this regard, we review the recent advancements in the investigation of non-linear optical properties of ZnS phosphors, where the knowledge of absorption and refraction is utilized in various optical and detector applications. Furthermore, the review highlights strategies employed to enhance the non-linear optical response of phosphor materials as well as a general discussion of an attosecond optical switching scheme which can be used to fabricate devices with petahertz speeds. Consequently, we provide a solution to the unsolved problem of the significant extension of optical limiting applications to switching applications by developing design strategies to manipulate conventional ZnS phosphor material. The potential challenges and future prospects of utilizing phosphor materials for switching applications are also addressed. The strategies for manipulating ZnS phosphor can be generalized for a broad range of other materials by minimizing linear and non-linear losses, while enhancing the values of the non-linear refractive index coefficient. We propose that the figure-of-merit of ZnS material can be enhanced by using a suitable combination of pump and probe wavelength values, which can be useful for optical switching applications.

“…8 Materials with a strong NLO effect have applications in telecommunications, optical data storage, optical switching, and high performance computing. [9][10][11][12] The optical properties of push-pull molecules can be optimized by modifying the strength of D and A groups as well as the length and nature of the p-linker, 13,14 thereby amplifying the ICT and increasing the NLO response. 8 The most commonly used electron donors are based on positive mesomeric or inductive effect (+M/+I) that include substituents such as -OH, -OR, -NH 2 , or -NR 2 as well as heteroaromatic rings such as thiophenes.…”
