title: Supercontinuum generation from a multiple-ring-holes tellurite microstructured optical fiber pumped by a 2 μm mode-locked picosecond fiber laser.
abstract: Supercontinuum (SC) generation from a highly nonlinear tellurite microstructured optical fiber with multiple rings of holes was demonstrated by pumping with a 2 μm mode-locked picosecond fiber laser. The chromatic dispersion of the fiber was measured with a homemade white-light spectral interferometer in a wide wavelength range and agreed with the theoretical calculation. Although the pumped wavelength was far from the zero dispersion wavelength, with flat dispersion profile of the fiber in the anomalous dispersion, the SC could be expanded from 650 to 2850 nm with launched pulse energy of several hundred picojoules. Simulations of SC generation agreed with the experimental results.
