Measured group birefringence and group velocity dispersion of elliptical-core ZBLAN fibres for mid-infrared supercontinuum generation
Shreesha Rao D. S., Christian R. Petersen, Anupamaa Rampur +2
Polarisation-maintaining ZBLAN optical fibres with small elliptical cores are attractive for nonlinear frequency conversion, for example in supercontinuum generation (SCG), and for…

A comprehensive diagnostics of new-generation dispersive elements based on Bragg structures was completed. The influence of inscription parameters on the properties of samples was…
Anticaustics in a Fabry-Perot interferometer
L. L. Sanchez-Soto, J. J. Monzon, G. Leuchs
We address the response of a Fabry-Perot interferometer to a monochromatic point source. We calculate the anticaustics (that is, the virtual wavefronts of null path difference) res…

We study how the nonlinear propagation dynamics of bulk states may be used to distinguish topological phases of slowly-driven Floquet lattices. First, we show how instabilities of…
Fractal-like photonic lattices and localized states arising from singular and nonsingular flatbands
Yuqing Xie, Limin Song, Wenchao Yan +5
We realize fractal-like photonic lattices using cw-laser-writing technique, thereby observe distinct compact localized states (CLSs) associated with different flatbands in the same…
