We report broad near-infrared soliton and associated dispersive wave source generation (1228–1867 nm) and tunable green third harmonic generation (528–542 nm) by LP11 mode excitation in a few-mode tellurite microstructure fiber pumped by a 1557 nm femtosecond fiber laser. The fiber presents a wide range of wavelengths in which the fundamental mode experiences normal dispersion, whereas the higher-order modes propagate in the anomalous dispersion regime. LP01 or LP11 mode can be selectively excited, and obviously different spectra are obtained based on the different mechanisms of supercontinuum generation.
