Nonlinear imaging through a golden spiral multicore fiber
arXiv:1806.01451 · doi:10.1364/OL.43.003638
Abstract
We report two-photon lensless imaging through a novel golden spiral multicore fiber. This unique layout optimizes the sidelobe levels, field of view, cross-talk, group delay and mode density to achieve a sidelobe contrast of atleast 10.9 dB. We demonstrate experimentally the ability to generate and scan a focal point with a femtosecond pulse and perform two-photon imaging.
