Project details - Ultrafast Nanooptics (left) Nanostructured microwire waveguide from LiNbO3 and Pt for efficient cascaded nonlinear interactions. (center) Geometry of the plasmonic slot-waveguide with Lithium Niobate in its core and the field profiles of the lowest and second … Radioengineering - April 2017, Volume 26, Number 1 [DOI: 10… The antenna consists of a substrate integrated waveguide, which operates in the fundamental mode TE10, and the rectangular ring-slot radiator with chamfered corners etched in the top wall of the SIW.

Here we show that a sizeable second-order nonlinearity at optical wavelengths is induced in a silicon waveguide by using a ... Second harmonic generation ...

Radioengineering - June 2016, Volume 25, Number 2 [DOI: 10… Experimental and simulated results showed that the proposed antenna with metamaterials performed broadband radar cross section reduction from 3.9 GHz to 18 GHz and the gain had been improved due to the coupling effect between slot and the …

We theoretically analyse quasi-phase matched second harmonic generation in a quadratic slot waveguide. Our results show that in this system both fundamental frequency and second harmonic (SH) modes can be confined in a nano-sized low-index region with the mode overlap integral intensity two orders

We present an optical microfiber-lithium niobate on insulator (MF-LNOI) hybrid waveguide for efficient second-order nonlinear processes. The structure combines the advantages of low-loss fiber and high-nonlinearity waveguide systems. We demonstrate the possibility of phase matching between fundamental and second harmonics in a wide spectral and dimensional range, and efficient second harmonic Silicon Nanoridge Array Waveguides for Nonlinear and

Second Harmonic Generation (SHG) is a coherent optical process of radiation of dipoles in the material, dependent on the second term of the expansion of polarization. The dipoles are oscillated with the applied electric field of frequency w, and it radiates electric field of 2w as well as 1w.
