The fiber is infused with 2-methyl, 4-nitroaniline (MNA) and enhanced via electric field poling. This process significantly boosts second harmonic generation and transmission performance by improving material crystallinity. Advanced microscopy and imaging reveal how the poling reshapes light guidance in the fiber. The results show how material engineering inside the fiber microstructure enables controllable nonlinear wavelength conversion\u2014an essential building block for fully integrated fiber-based photonic systems. The work paves the way for next-generation in-fiber light switching and<\/p><p>wavelength conversion devices.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-afe08ff
