1 Sep 2016 | Abstract: | We vary the time-frequency mode structure of ultrafast pulse-pumped
modulational instability (MI) in an argon-filled hollow-core kagom’e-style PCF
by adjusting the pressure, pump pulse chirp, fiber length and parametric gain.
Compared to solid-core systems, the pressure dependent dispersion landscape
brings increased flexibility to the tailoring of frequency correlations. The
resulting mode content is characterized by measuring the multimode second-order
correlation function g(2) and by directly observing frequency correlations in
single-shot MI spectra. We show that, from such measurements, the shapes and
weights of time-frequency Schmidt (TFS) modes can be extracted and that the
number of modes directly influences the shot-to-shot pulse-energy and
spectral-shape fluctuations in MI. Using this approach we are able to change
the number of TFS modes from 1.3 (g(2) = 1.75) to 4 (g(2) = 1.25) using only a
single fiber. | Source: | arXiv, 1609.0257 | Services: | Forum | Review | PDF | Favorites |
