  • Demonstration of a photonic-lantern focal-plane wavefront sensor using fiber mode conversion and deep learning 

    Norris, Barnaby; Wei, Jin; Betters, Christopher H.; Leon-Saval, Sergio G.; Xin, Yinzi; Lin, Jonathan; Kim, Yoo Jung; Sallum, Steph; Lozi, Julien; Vievard, Sebastian; Guyon, Olivier; Gatkine, Pradip; Jovanovic, Nemanja; Mawet, Dimitri; Fitzgerald, Michael P.
    Published 2022
    A 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 ...

  • The photonic lantern wavefront sensor and imager: focal plane wavefront sensing and optimal imaging at the diffraction limit and beyond 

    Norris, Barnaby; Leon-Saval, Sergio G.; Wei, Jin; Betters, Christopher H.; Taras, Adam; Lin, Jonathan; Xin, Yinzi; Kim, Yoo Jung; Fitzgerald, Michael; Sallum, Steph; Sengupta, Aditya; Gatkine, Pradip; Jovanovic, Nemanja; Mawet, Dimitri; Lozi, Julien; Vievard, Sebastian; Deo, Vincent; Lallement, Manon; Levinstein, Daniel; Guyon, Olivier
    Published 2024
    The 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 ...

  • Optimization of nonlinear enhancement through linear dispersion engineering 

    Lourdesamy, Joshua P.; Widjaja, Justin; Hawi, Georgio; Kesarwani, Sharvil; Runge, Antoine F. J.; de Sterke, C. Martijn
    Published 2023
    We 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 ...

  • Absence of Galilean invariance for pure-quartic solitons 

    Widjaja, Justin; Kobakhidze, Erekle; Cartwright, Tiernan R; Lourdesamy, Joshua P.; Runge, Antoine F. J.; Alexander, Tristram J.; de Sterke, C. Martijn
    Published 2021
    Optical 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 ...

  • Theory of multicolor soliton microcombs 

    Silvestri, Carlo; Widjaja, Justin; Lin, Austin; de Sterke, C. Martijn; Runge, Antoine F. J.
    Published 2025
    We 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 ...
