OPTICAL FIBER WITH SPECIALIZED FIGURE-OF-MERIT AND APPLICATIONS THEREFOR

摘要

A specialized, dispersion-controlled fiber is particularly configured to exhibit a relatively uniform dispersion (D) over a broad spectral range (for example, 1000 nm to 2000 nm). The specialized fiber exhibits an essentially constant attenuation (α) over this same spectral range so that the fiber is defined as having a high “figure of merit” (FoM) where FoM is defined as |D|/α. The specialized fiber is well-suited for use as a pulse stretcher, providing the ability to separate out wavelength constituents of an extremely short (fs, ps) broadband pulse into the ns range, for example.
