    Abstract: The present invention relates to a method for producing narrow spectral linewidths more particularly by narrowing the full wave half maximum (FWHM) linewidth to a narrowed spectral linewidth. One of the advantages of the method of the present invention is to detect molecular bonding in analyte via contactless approach optical sensor. Another advantage of the present invention is that each LED has its own broader FWHM spectral linewidth and narrowing the linewidth to its unique and precise wavelength which contributes to more accurate observations and determination of analyte concentration.

    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.
