摘要： Methods and systems include generating one or more mid-infrared frequencies based at least upon electron transitions in one or more quantum cascade heterostructures. The quantum cascade heterostructures are concurrently configured with a significant second-order nonlinear susceptibility, a significant third-order nonlinear susceptibility, and an insignificant group velocity dispersion. A set of mid-infrared frequencies (that may include a frequency comb) is generated in the quantum cascade heterostructures based at least upon a four-wave mixing of the one or more mid-infrared frequencies. The four-wave mixing arises at least from the significant third-order nonlinear susceptibility and the insignificant group velocity dispersion. A set of terahertz frequencies (that may include a frequency comb) is generated in the quantum cascade heterostructures based at least upon a difference frequency generation from mid-infrared frequency pairs selected from the set of mid-infrared frequencies. The difference frequency generation arises at least from the significant second-order nonlinear susceptibility.

摘要： The invention provides a system and a method for wavelength referencing and polarization mitigation. An optical wavelength tunable laser source is swept in a number of contiguous, overlapping sweep segments. A coarse reference wavelength section produces a reference signal that defines at least one absolute wavelength within a sweep segment. A fine wavelength reference section produces a periodic wavelength reference signal that defines a plurality of equidistant wavelengths within each sweep segment with an indeterminate offset relative to the absolute wavelength(s) of the coarse reference wavelength section. The free spectral range of the fine wavelength reference section is smaller than the spacing between subsequent absolute reference wavelengths of the coarse reference wavelength section. This arrangement allows reducing the minimum required overlap between contiguous sweep segments.
