Ultrabroad supercontinuum generation in tellurite equiangular spiral photonic crystal fiber. Agrawal, A., Tiwari, M., Azabi, Y., Janyani, V., Rahman, B., & Grattan, K. Journal of Modern Optics, 2013. abstract bibtex Simulations are presented of a very broad and flat supercontinuum (SC) in both the normal and anomalous group velocity dispersion regimes of the same equiangular spiral photonic crystal fiber at low pumping powers. For a pump wavelength at 1557 nm and average pump power of 11.2 mW, we obtained a bandwidth >3 μm (970 nm-4100 nm) at 40 dB below the peak spectral power with fiber dispersion ∼2.1 ps/km nm at 1557 nm. In the same fiber, at pump wavelength 1930 nm and average pump power of 12 mW the SC bandwidth was more than two octaves (1300 nm-3700 nm) and dispersion was ∼1.3 ps/km nm at 1930 nm. This demonstrates the potential use of the fiber for multi-wavelength pumping with commercially available sources at fairly low power. © 2013 Copyright Taylor and Francis Group, LLC.
