Demonstration of a photonic-lantern focal-plane wavefront sensor using fiber mode conversion and deep learning
Published 2022A focal plane wavefront sensor offers major advantages to adaptive optics, including removal of non-commonpath error and providing sensitivity to blind modes (such as petalling). But simply using the observed point spread ...Conference paper -
The photonic lantern wavefront sensor and imager: focal plane wavefront sensing and optimal imaging at the diffraction limit and beyond
Published 2024The use of a photonic lantern as focal plane wavefront sensor has seen recent widespread interest - it can remove non-common-path aberrations, accurately sense low-wind-effect and petal modes, and provide wavelength ...Conference paper -
Optimization of nonlinear enhancement through linear dispersion engineering
Published 2023We consider nonlinear pulse propagation in media with a dispersion relation exhibiting $J$ periodically spaced identical maxima in a co-moving frame. The nonlinear interactions lead to $J$ pulses centered at each of these ...Open AccessArticle -
Absence of Galilean invariance for pure-quartic solitons
Published 2021Optical temporal solitons, arising from self-phase modulation and negative quadratic ($\beta_2$) dispersion, are Galilean invariant, and therefore their properties do not depend on their group velocity. This is no longer ...Open AccessArticle -
Theory of multicolor soliton microcombs
Published 2025We present a general theory of multicolor soliton microcombs. These frequency combs require engineered dispersion and have an optical spectrum consisting of multiple spectral windows, centered at distinct frequencies. Our ...Open AccessArticle
