    Computer-generated holograms embedded in bulk silicon with nonlinear laser lithography
    (IEEE, 2016) Turnalı, Ahmet; Tokel, Onur; Makey, Ghaith; Pavlov, Ihor; İlday, Fatih Ömer
    Recently, we have showed a direct laser writing method to form subsurface structures inside silicon by exploiting nonlinear interactions. Here, we demonstrate utilization of this phenomenon to create computer-generated holograms buried in silicon.

    Physical model for subsurface silicon writing
    (IEEE, 2016) Tokel, Onur; Turnalı, Ahmet; Pavlov, Ihor; İlday, Fatih Ömer
    We have recently reported a direct laser writing method enabling buried structures deep inside silicon. Here we study the formation of these subsurface structures. We take advantage of Nonlinearity Engineering to understand this new phenomenon.
