Abstract
Official abstract text for this publication.
Embodiments of the present invention are generally related to embodiments of the present invention relate to a fiber stretchers module for use in the 1550 nm wavelength range. In one embodiment of the present invention, a fiber stretcher module for use in the 1550 nm wavelength range comprises a first fiber comprising a relative dispersion curve value of greater than about 0.0002 nm −2 and a dispersion value of less than about −60 ps/(nm·km) at about 1550 nm, and a second fiber comprising a relative dispersion curve value of about zero and a relative dispersion slope value of about 0.003 nm −1 at about 1550 nm, wherein the fiber stretcher module comprises a collective relative dispersion slope of about 0.0413 nm −1 and a relative dispersion curve of about 0.00286 nm −2 at 1550 nm.
First claim
Opening claim text (preview).
What is claimed is: 1. An optical fiber stretcher module for use in the 1550 nm wavelength range comprising: a first fiber having a relative dispersion slope, RDS, and a relative dispersion curvature, RDC, wherein a ratio of the slope to the curvature is less than about 30 nm, and having a dispersion value of between about −20 ps/(nm·km) to about −100 ps/(nm·km) at about 1550 nm, wherein the RDS of the first fiber in the 1550 nm range is between about 0.004 nm −1 to about 0.03 nm…
