Abstract
Aspects of the present disclosure describe improved supercontinuum generation based upon alternating optical dispersion along a waveguide length that advantageously generates much more spectral bandwidth than possible with conventional, prior art techniques without losing coherence as well as supporting a larger range of pulse energies (i.e., for lower than conventionally allowed pulse energies or high pulse energies).
Claims18
A waveguide structure for supercontinuum generation CHARACTERIZED BY:
- alternating segments of normal dispersion (ND) waveguide segments and anomalous dispersion (AD) waveguide segments along a length of the waveguide structure;
- wherein the alternating segments are configured such that spectral generation of optical pulses traversing the structure is effected in the ND segments and spectral bandwidth increase in the AD segments is less than or equal to 10% relative to spectral bandwidth increase in the preceding ND segment.
A waveauide structure for supercontinuum generation CHARACTERIZED BY:
- alternating seaments of normal dispersion (ND) waveguide segments and anomalous dispersion (AD) waveguide segments along a length of the waveguide structure;
- wherein the alternating segments are configured such that spectral generation of optical pulses traversing the structure is effected in the AD segments and spectral bandwidth increase in the ND segments is less than or equal to 10% relative to spectral bandwidth increase in the preceding AD segment.
A waveguide structure for supercontinuum generation CHARACTERIZED BY:
- alternating segments of normal dispersion (ND) waveguide segments and anomalous dispersion (AD) waveguide segments along a length of the waveguide structure;
- wherein the alternating segments are configured such that supercontinuum spectral generation of optical pulses traversing the structure is effected in both AD and ND segments, and wherein the pulses are temporally compressed in one of the segment types and temporally expanded in the other one of the segment types and spectral clamping is absent in both segment types and where spectral bandwidth increase in neighboring AD and ND segments are both more than 10%.
