In a channel waveguide structure, schematically shown in Fig. 10.4, the light is confined not only in the transverse direction, but also in the lateral one. This confinement is caused by the lateral contrast of the (effective) refractive indices between the channel region, Aleff-c> and the slab, Neff-s> i.e., Neff-c > Neff s- This contrast can be established by the presence of a ridge in the core section, where the...

Fig. 1. Examples of the two common integrated optics waveguides used SHG in organic materials (a) slab waveguide, (b) channel waveguide. The dimensions along the confinement directions are typically a few optical wavelengths. The core optical index made from the polymer film is higher that the substrate ns. and cladding nc indices...
