Observation of bound states in Lieb photonic lattices
Rodrigo A. Vicencio, Camilo Cantillano, Luis Morales-Inostroza +4
We present the first experimental demonstration of a new type of bound states in the continuum, namely, compacton-like linear states in flat bands lattices. To this end, photonic L…
Random dimer model in pseudo two-dimensional lattices
Uta Naether, Cristian Mejía-Cortés, Rodrigo A. Vicencio
In this work, we study long-time wave transport in correlated and uncorrelated disordered 2D arrays. When a separation of dimensions is applied to the model, we find that the predi…
Photorefractive writing and probing of anisotropic linear and non-linear lattices
Raphaël Allio, Diego Guzmán-Silva, Camilo Cantillano +5
We study experimentally the writing of one- and two-dimensional photorefractive lattices, focusing on the often overlooked transient regime. Our measurements agree well with theory…
Analytical model for waveguide light propagation and applications
Santiago Rojas Rojas, Luis Morales-Inostroza, Uta Naether +6
We study the polarization properties of elliptical femtosecond-laser-written waveguides arrays. A new analytical model is presented to explain the asymmetry of the spatial transver…
Experimental observation of bulk and edge transport in photonic Lieb lattices
D. Guzman-Silva, C. Mejia-Cortes, M. A. Bandres +6
We analyze the transport of light in the bulk and at the edge of photonic Lieb lattices, whose unique feature is the existence of a flat band representing stationary states in the…
