摘要： A stretcher fiber includes a core region, inner trench region, ring region, outer trench region, and outer cladding region. The core region has a radius r1, a refractive index n1, and a positive effective refractive index Δn1 with respect to an outer cladding region having an outer radius r0 and a refractive index no, where Δn0 is equal to n1−n0. The inner trench region surrounds the core region and has an outer radius r2, a refractive index n2 less than n0, and a negative effective refractive index Δn2 equal to n2−n0. The ring region surrounds the trench region and has an outer radius r3, a refractive index n3 greater than n0, and a positive effective refractive index Δn3 equal to n3−n0. The outer trench region surrounds the ring region and has an outer radius r4, a refractive index n4 less than n0, and a negative effective refractive index Δn4 equal to n4−n0. The outer cladding region surrounds the outer trench region. The values of r0, r1, r2, r3, r4, Δn1, Δn2, Δn3, and Δn4 cause the fiber to have a negative dispersion and to have a relative dispersion slope greater than 0.005 nm− at a specific wavelength within a selected operating wavelength band. Additionally, the stretcher may be used in combination with a second fiber to match the dispersion and RDS of a selected grating compressor.
