Planar photonic crystals infiltrated with liquid crystals: optical characterization of molecule orientation

Romuald Houdré, Libero Zuppiroli, Rolando Ferrini, Liza Carol Andrea Dunbar, Barbara Wild, Vasily Zabelin

Nematic liquid crystals are infiltrated into InP-based planar photonic crystals. Optical measurements as a function of temperature and polarization are used to study the average director field configuration in the nanometer-size holes: a planar equilibrium ...

Liquid crystal infiltration of InP-based planar photonic crystals

Romuald Houdré, Frank Nüesch, Libero Zuppiroli, Rolando Ferrini, Liza Carol Andrea Dunbar, Barbara Wild

A procedure for the infiltration of planar photonic crystals (PhCs) with liquid crystals (LCs) is presented. InP-based PhCs are infiltrated with the nematic LC-K15 in a specially designed high-vacuum chamber. The infiltration technique is validated and sys ...

Étude expérimentale des propriétés optiques des cristaux photoniques bidimensionnels et de leur accordabillité

Barbara Wild

Photonic crystals are periodic dielectric structures, where the periodicity varies in one, two or three dimensions. Analogous to the periodic potential of electrons in semiconductors, the periodic variation of the dielectric constant influences the electro ...

Tuning the optical properties of planar photonic crystals by liquid crystal infiltration

Romuald Houdré, Libero Zuppiroli, Rolando Ferrini, Liza Carol Andrea Dunbar, Barbara Wild

Recently there has been a growing amount of attention devoted to tuneable photonic crystals (PhCs) where the optical response of PhC structures can be dynamically modified. We will show how infiltrating planar PhCs with a synthetic organic material allows ...
