Femtosecond pulse compression in a hollow-core photonic bandgap fiber

A common method of temporally compressing ultrashort pulses is to first spectrally broaden the pulses via self-phase modulation in an optical fiber and then more or less correct (flatten) their spectral phase with a dispersive optical element such as a pair of diffraction. We present the design of single-mode fibers for two-stage higher-order soliton compression at 2 µm wavelength and achieve high-degree pulse compression in cascaded single-mode fibers. The compression performance for the initial input pulse width from 1 to 50 ps is also investigated. Time transformation (TT) approach and symmetrized split step Fourier method (SSFM) are compared here to obtain the compressed optical pulses.
