Theoretical analysis of enhanced second-harmonic generation based on a self-formed antiguide structure91(2002); http://dx.doi.org/10.1063/1.1474616View Description Hide Description
An antiguide structure having a core of lower refractive index confines lightwaves owing to Fresnel multiple reflection. Within a planar waveguide of a nonlinear-optical photoconductive polymer, the second-harmonic wave generated under the Cerenkov-radiation type phase matching can shape the antiguide structure to increase the second-harmonic power itself due to the optical confinement. Here, we theoretically analyze the enhancement.

Cell gap thickness is one of the most important design parameters for liquid crystal displays(LCD). Existing measurement methods only apply to transmittive LC cells. These methods are obviously unsuitable for measuring the cell gaps of reflective LCDs with internal reflectors. This kind of LCD includes single polarizer reflective displays and liquid crystal on silicon displays. The objective of this article is to introduce various reflective methods of LCD cell characterization that are both applicable to transmittive and reflective LCDs.
