Abstract:
We report on both the fabrication and the application of a Ge–Se–Te glass-based suspended core fiber for mid-infrared supercontinuum generation. A two-octave spanning mid-infrared light source (from 3.25 to 13 µm) is experimentally demonstrated by pumping the chalcogenide fiber with sub-100 fs pulses at 8.6 µm. Numerical simulations of nonlinear pulse propagation as well as fiber properties are also provided and support experimental measurements.Keywords:

We report supercontinuum generation from an all-normal dispersion SiGe-on-Si waveguide pumped with 205 fs pulses at 4 μm. The supercontinua are spanning over an octave for both orthogonal polarizations of the fundamental mode.

We investigate the dispersion and nonlinear properties of a graded-index ring-core fiber (GIRCF) with different shape factors. An over two-octave supercontinuum can be formed in the GIRCF with a shape factor of 2.

We report on octave-spanning supercontinuum generation in a 400-nm-thick silicon nitride waveguide coated with tellurite glass. An octave-spanning supercontinuum is achieved at a low peak power of 482 W using a 100-fs laser centered at 1565 nm.

We fabricate highly nonlinear and mechanically robust step-index chalcogenide nanotapers with high index contrast for stable mid-infrared supercontinuum generation. By pumping the nanotapers with low peak-power pulses, one-octave of spectral broadening was generated.

Traditional optomechanical research is rarely studied in compound glass, especially chalcogenide glass. In this paper, the forward and backward Stimulated Brillouin Scattering (SBS) is demonstrated for the first time in a chalcogenide glass microsphere resonator. A high-purity chalcogenide glass microsphere with a high quality (Q) factor of 2.1 × 107 is investigated using a 1550 nm tunable laser. In the experiment, the resulting mechanical vibration frequencies caused by forward and backward SBS are measured at 80 MHz and 7.8 GHz, respectively. The triply resonant Stimulated Brillouin scattering process greatly enhances the light–acoustic interactions, enabling the threshold power to be 344 μW. The work demonstrated in the chalcogenide microresonator is important for the potential applications of chalcogenide glass, which has higher nonlinearity and low absorptions at mid-infrared band.

A 1.2-octave-spanning supercontinuum generation is demonstrated in a 3-mm-long ultra-silicon-rich-nitride waveguide using 17pJ, 500fs pulses. The generated supercontinuum possesses a spectral coherence (| g 12 |) exceeding 0.94 on average across the measured wavelength range.
