Domains in ferroelectrics were considered to be well understood by the middle of the last
century: They were generally rectilinear, and their walls were Ising-like. Their simplicity …

Patterning ferroelectric domains to engineer devices is a relatively recent phenomenon. It is
practiced on nonlinear optical materials to make micrometer-sized devices and on …

A large number of oxides has been investigated in the last twenty years as possible new
materials for various applications ranging from opto-electronics to heterogeneous catalysis …

Density-functional theory calculations of the LiNbO 3 (2 1¯ 1¯ 0),(1 1¯ 00), and (0001)
surfaces, commonly referred to as X, Y, and Z cuts, are presented. In case of the Z cut, we …

The authors demonstrate how slow group velocities that are easily attainable at the band
edge of photonic crystals can drastically enhance the electro-optical effect on tunable …

We report the successful fabrication of high-aspect-ratio lithium niobate (LN) nanostructures
by using femtosecond-laser-assisted chemical etching. In this technique, a 1 kHz …

Lens effect was obtained in an open microfluidic system by using a thin layer of liquid on a
polar electric crystal like LiNbO3. An array of liquid micro-lenses was generated by …

Nonlinear optical interactions involving counter-propagating photons are of great interest for
both classical and quantum optical applications. However, their use is sparsely spread due …

We review the techniques used for fabrication of bulk sub-micrometer ferroelectric domain
gratings in KTiOPO_4 (KTP) and demonstrate that bulk Rb-doped KTiOPO_4 (RKTP) is an …

Reflection loss on the optical component surface is detrimental to performance. Several
researchers have discovered that the eyes of moths are covered with micro-and …
