| - FIG. 1C illustrates in graphic form the relative relationship between the pump wavelength, ??P, the signal wavelength, ??S, and the idler wavelength, ??I. For a given tuned pump wavelength, ??P, and tuned signal or injection wavelength, ??S, such as indicated at ???X???, an idler mid-IR frequency, ??I, can be achieved based on a given periodic poled grating of NFM device 16.
