Photoalignment materials, such as the azobenzene-based PAAD series studied here, are becoming increasingly important in liquid crystal-based optical devices and displays. Yet their properties and, in particular, their response to light, are still not

Enhanced, photoactive response can be realised by integrating liquid crystals with photoalignment or photoconductive alignment layers. Such cells, asymmetric by design, need to be monitored for the stability and uniformity, especially in the regions

Nematic liquid crystals integrated with metallic resonators (metamaterials) are intriguing hybrid systems, which not only offer added optical functionalities, but also promote strong light-matter interactions. In this report, we show with an analytic

We report on orientational, optical nonlinearity of nematic liquid crystals (NLCs), observed when integrated with THz metallic metamaterial (MM) resonators. Our findings show that the bulk NLCs orientation breaks down close to the MM-NLC interface. T

We report that Babinet complementary patterns of metamaterials (MMs) do not exhibit the same frequency tuning range when integrated with nematic liquid crystals (NLCs). The results of our numerical and experimental studies suggest that this behaviour

In Quebec City, facing north, from the Pierre-Dugua-De-Mons Terrace (a small hill close to the city centre), there is a particularly spectacular view overlooking the city (see Figure 1). The view h...

We present an intuitive and efficient method for modeling light propagation in layered isotropic and anisotropic media, which we call the Iterated Ray Method. Considering a single layer sandwiched between semi-infinite layers, the infinite reflected

Babinet complementary patterns of a spectrally tunable metamaterial incorporating a nematic liquid crystal are normally assumed to exhibit the same tuning range. Here we show that for a hybrid, terahertz liquid crystal-metamaterial, the sensitivity o

Controlling the crystallization behavior of semicrystalline polymers is of paramount importance since it largely determines their final properties. A way to affect crystallinity is via the addition of (nanosized) additives to the polymer matrix, comm

Liquid Crystals XXII.
Azobenzene-based complex dyes (PAAD) have found many applications, in particular in liquid crystal based waveplates and flat lenses [1-2]. We investigated PAAD layers, both as individual thin films and as an alignment layer in liquid crystal waveplat
