Few-cycle mid-infrared pulses from BaGa2GeSe6
(2020-07-01)
Article
Open AccessBaGa2GeSe6 (BGGSe) is a newly developed nonlinear material that is attractive for ultrabroad frequency mixing and ultrashort pulse generation due to its comparably low dispersion and high damage threshold. A numerical study ... -
Flat lensing by periodic loss-modulated materials
(2013-09-23)
Article
Open AccessWe propose a flat lensing effect using a periodic loss-modulated material. In particular, we consider a two-dimensional square and rhombic arrangement of lossy cylinders embedded in a host media with the same refractive ... -

Prospects of new planar optical waveguides based on eutectic microcomposites of insulating crystals: The ZrO 2 (c)-CaZrO 3 erbium doped system
(1997-11-10)
Article
Restricted access - publisher's policyA new approach to produce structured optical materials is described. The method relies on the capability of growing eutectic crystals of wide optical band gap materials by directional solidification procedures. The laser ... -
Resonant, broadband, and highly efficient optical frequency conversion in semiconductor nanowire gratings at visible and UV wavelengths
(2019-08-01)
Article
Restricted access - publisher's policyUsing a hydrodynamic approach, we examine bulk- and surface-induced second- and third-harmonic generationfrom semiconductor nanowire gratings having a resonant nonlinearity in the absorption region. We demonstrateresonant, ...
