Time-frequency distribution of interferograms from a frequency comb in dispersive media.
We investigate general properties of the interferograms from a frequency comb laser in a non-linear dispersive medium. The focus is on interferograms at large delay distances and in particular on their broadening, the fringe formation and shape. It is observed that at large delay distances the interferograms spread linearly and that its shape is determined by the source spectral profile. It is ...
متن کاملDual-pump frequency comb generation in normally dispersive optical fibers
We show that tunable frequency combs can be generated by launching two continuous-wave pumps at slightly different wavelengths into a normally dispersive optical fiber. The dual-pump configuration allows the tuning of comb spacing into the terahertz regime. Different pump powers and frequency separations are explored numerically to determine the effect of the input parameters on frequency comb ...

15 صفحه اولOptical frequency comb spectroscopy.
Optical frequency combs offer enormous potential in the detection and control of atoms and molecules by combining their vast spectral coverage with the extremely high spectral resolution of each individual comb component. Sensitive and multiplexed trace gas detection via cavity-enhanced direct frequency comb spectroscopy has been demonstrated for various molecules and applications; however, pre...
متن کاملJoint Time-Frequency and FDTD Analysis of Precursor Fields in Dispersive Media
Superluminal group velocities, defined as group velocities exceeding the speed of light in vacuum, c, have been theoretically predicted and experimentally observed in various types of dispersive media, such as passive and active Lorentzian media, one-dimensional photonic crystals, and undersized waveguides. Though the group velocity was found to be superluminal in these media, it has been sugge...
