Ultrabroadband, Midinfrared Supercontinuum Generation in Dispersion Engineered As 2 Se 3 -Based Chalcogenide Photonic Crystal Fibers

Résumé

Small core As 2 Se 3 -based photonic crystal fibers (PCFs) are accurately characterized for compact, high power, ultrabroadband, and coherent supercontinuum generation within few millimeters fiber length. Bandwidths of ~ 5.3 μ m, 5 μ m, and 3.2 μ m were calculated for hole-to-hole spacings Λ = 3.5 μ m, 4.5 μ m, and 5.5 μ m, respectively. The spectral broadening in the chalcogenide PCF is mainly caused by self-phase modulation and Raman-induced soliton self-frequency shift. The results show that small core As 2 Se 3 PCFs are a promising candidate for mid-IR SCG up to ~ 8 μ m.
