Abstract:
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.

Claim (Index 1):
An optical fiber comprising\n a core region including\n an up-doped central core area having a diameter in the range of 2-4 \u03bcm; \n a down-doped trench surrounding the up-doped central core area and having a diameter in the range of 5-9 \u03bcm, where the change in refractive index \u0394n 1  between the up-doped central core area and the down-doped trench has a value of at least 0.020; and \n an outer core region surrounding the down-doped trench and having a thickness of about 4 \u03bcm such that the complete core region exhibits a diameter in the range of 9-13 \u03bcm, the outer core region having a refractive index value greater than the down-doped trench with a \u0394n e  between the trench and the outer core region being in the range of about 0.005-0.015; \n a cladding region surrounding the core region and including\n an inner cladding layer having a first refractive index value; \n an outer cladding layer surrounding the inner cladding layer and having a second refractive index value greater than the first refractive index value; and \n a coating layer surrounding the cladding region, where the thicknesses of each region and their respective index values are selected to form an optical fiber exhibiting a relatively high and uniform figure-of-merit (FoM) over a broad spectral range, where FoM is defined as:\n FoM=| D|/\u03b1,  \n where |D| is an absolute value of dispersion in a propagating optical signal and \u03b1 is attenuation of the propagating optical signal, both |D| and \u03b1 measured as a function of wavelength.
