Laser Beam Shaping Using a Photoinduced Azopolymer Droplet-Based Mask
R. Barille, A. Korbut, S. Zielinska +2
The dewetting of an azopolymer droplet, followed by the photostructuration of the evaporated droplet, is employed to create an amplitude mask. This straightforward process yields a…
Anisotropic Confinement of Chromophores Induces Second-Order Nonlinear Optics in a Nanoporous Photonic Metamaterial
Karolina Waszkowska, Pierre Josse, Clement Cabanetos +8
Second-order nonlinear optics is the base for a large variety of devices aimed at the active manipulation of light. However, physical principles restrict its occurrence to non-cent…
Surface quasi periodic and random structures based on nanomotor lithography for light trapping
Sh. Golghasemi Sorkhabi, S. Ahmadi-Kandjani, F. Cousseau +4
We compare the characteristics of two types of patterns obtained with two azopolymer materials: a Gaussian random pattern and a quasi-random grating pattern. The surface structurat…
A New Method for Patterning Azopolymer Thin Film Surfaces
Sh. Golghasemi Sorkhabia, R. Barille, S. Ahmadi-Kandjani +2
We present a simple bottom-up approach via an incoherent unpolarized illumination and the choice of a solvent-droplet-induced-dewetting method to photoinducenano doughnuts on the s…
Linear absorption coefficient of in-plane graphene on a silicon microring resonator
Heng Cai, Yahui Cheng, He Zhang +4
We demonstrate that linear absorption coefficient (LAC) of a graphene-silicon hybrid waveguide (GSHW) is determined by the optical transmission spectra of a graphene coated symmetr…
Near-Field Optical control of Doughnut-Shaped Nanostructures
A. M. Dubrovkin, R. Barille, E. Ortyl +1
The application of a local near-field optical excitation can be used to control step-by-step the reshape of individual doughnut-shaped azopolymer nano-objects by varying the time o…
