Abnormal reflecting mirror (ARM) structures, consisting of a corrugated optical waveguiding structure, can serve as a wavelength-selective end mirror in a laser cavity. The ARM structure shows, for each wavelength in a certain region, 100% reflection

In this paper we analyse the second harmonic generation of TM polarisation in a planar waveguide with a non-linear anisotropic substrate using the coupled mode theory under the non-depleted pump approximation. It is an extention of our previous paper

It is well known that in the non-depleted pump approximation, the efficiency of a second harmonic generation (SHG) of a guided mode in a non-linear optical waveguide increases quadratically with the interaction length (P 2 ∝ L 2), and linearly (P 2

Čerenkov waveguide SHG: a less critical way to reach the efficiency peak

Autor: H.J.W.M. Hoekstra, Jiří Čtyroký, L. Kotacka

It is well known that the conversion efficiency of the SHG in the Cerenkov regime in a waveguide with a nonlinear substrate exhibits a very sharp peak. Its position in a "pump wavelength-guide thickness" diagram follows a modified dispersion relation
