Abstract Tunable supercontinuum generation (SCG) is reported and analyzed numerically using nematic liquid crystal infiltrated photonic fiber (NLC-PCF). The optical properties of the supported modes including nonlinearity dispersion are controlled an external applied voltage or temperature due to NLC infiltration. modal analysis suggested design studied full vectorial finite element method. pulse propagation then implemented a modified nonlinear Schrödinger equation. effects geometrical parameters, rotation angle on performance investigated. proposed NLC-PCF achieves tunable bandwidth with broadband light spectrum. At ϕ = 90° T 25°C, SC spectrum equal 6681 nm at length 5 mm λ 1550 nm. Additionally, 0°, 11025 achieved same device length. SCG has advantages large high tunability relative those presented in literature

Abstract Ten to 25 μm‐long‐wavelength mid‐infrared laser has broad application prospects in fields such as military, industrial, medical, and spectroscopy. Currently, lasers capable of emitting 10–25 radiation include CO 2 lasers, solid‐state quantum cascade infrared supercontinuum light sources, free electron lasers. This review summarizes the development status these five types providing a detailed analysis summary their operating principles, advantages, limitations, future outlooks. The aim is offer valuable reference information for related research promote further tunable at μm.
