Abstract
The discovery of a clear correlation between the Anderson localization length and the dispersion properties of highly localized TALOF modes allowed us to demonstrate that the zero dispersion wavelength can be tuned over more than 300 nm within the same fiber by selected excitation of specific modes. This enabled apparatus and methods for generating tunable, multi-octave-spanning supercontinuum (SC) spectra in a bandwidth from 460 nm to 1750 nm. Associated applications are also presented.
Claims13
A tunable, multi-octave-spanning supercontinuum (SC) generating apparatus, comprising:
- a pump laser;
- and
- a length of TALOF characterized by a plurality of Anderson mode propagation channels each characterized by an Anderson mode localization length between 2 to 15 microns (μ), operationally disposed to receive the pump laser output at an input end thereof.
A method for generating tunable, multi-octave supercontinuum (SC) spectra, comprising:
- providing a pump laser characterized by a spectral output wavelength between 400 nm to 2400 nm, a laser linewidth between 0.1 nm to 40 nm, and a peak pulse power between 100 W and 1 MW;
- providing a length of TALOF having a plurality of Anderson mode propagation channels each characterized by an Anderson mode localization length between 2μ to 15μ;
- inputting the pump laser output to a respective Anderson mode propagation channel to excite an Anderson mode having a zero dispersion wavelength (ZDW) sufficiently matching the pump laser output wavelength to generate a SC output spectrum from the respective channel.
