Abstract

A high confinement nonlinear optical fiber is provided along with methods of parametric amplification for use thereof The nonlinear optical fiber may include a plurality of concentric layers which are configured to provide different guiding regimes to low-frequency and high-frequency components through transverse geometry and refractive index profiling, thus reducing waveguide dispersion. The resulting optical fiber provides a parametric device with phase-matching in any spectral region of interest, such that a fiber optic parametric amplifier (FOPA) implementing the optical fiber can amplify in any spectral window of interest. A narrow-band FOPA configured to minimize phase mismatching is also provided for use with the optical fiber, and may be implemented as a light source or a monochromator.

First claim

What is claimed is:

1. A transverse geometry-insensitive optical fiber, comprising:
an inner core having a first refractive index and an inner core radius;
an outer core concentrically surrounding the inner core, the outer core having a second refractive index less than the first refractive index and an outer core radius, wherein a difference between the second refractive index and the first refractive index defines an index contrast, wherein the inner core radius and the outer…
