Design of an elliptical air-hole dual-core photonic crystal fiber for over two octaves spanning supercontinuum generation

Effects of environmental metal and metalloid pollutants on plants and human health: exploring nano-remediation approach

“…Although HMMs are needed at low concentrations for the proper operation of many plant organs, they become hazardous to plants when their levels rise above the safe threshold. As time goes by, the HMMs reputation as important pollutants only grows (Rahman Md Ashfaqur Rahman Md Asiful Islam Shah Alam Zahidur Rahman et al 2019 ). While some metals, such as Cu, Mn, Fe, Zn, Co, and Ni, are essential for plant growth as micronutrients, others, such as Cd, Cr, and Pb, are of little use to plants and can be toxic if present in excess for an extended period (Fig.…”

Tellurite glass based optical fiber for the investigation of supercontinuum generation and nonlinear properties

“…In another article, Van Hoana et al inscribed that the SC spectrum pump wavelength of 1030 nm bandwidth is -850 1250 nm, with input pulse fs 400 and energy nJ 25 [10]. Another researcher Rahman et al [11] reported a fused silica-based PCF, where they achieved a pumping wavelength of 1060 nm with a pulse duration of fs 50 and an average power of 322 mW and the SC spectrum bandwidth is between 400 and 1800 nm. Numerical computations of the SCG in the toluene-filled 4 cm long PCF have been manifested by Lanh Van et al [12], where the SC spectrum range is between 1000 and 1700 nm.…”
