Numerical investigations of two-dimensional photonic crystal optical properties, design and analysis of photonic crystal based structures

Vasily Zabelin

Two-dimensional (2D) photonic crystals (PhCs) operating in the near-infrared wavelengths are promising candidates for novel integrated optics applications. In this work the optical properties of the Bloch modes in 2D photonic crystals have been investigate ...

Influence of residual disorder on the anticrossing of Bloch modes probed in k space

Romuald Houdré, Nicolas Le Thomas, Vasily Zabelin

We retrieve the dispersion properties of photonic crystal waveguides near the band edge with high experimental accuracy. The dispersion diagram of the waveguide modes in the complex-valued plane is directly measured in the far ﬁeld by using a Fourier space ...

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

Romuald Houdré, Rolando Ferrini, Libero Zuppiroli, 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 ...

Experimental observation of slow mode dispersion in photonic crystal coupled-cavity waveguides

Romuald Houdré, Nicolas Le Thomas, Jana Jágerská, Vasily Zabelin

We experimentally investigate the dispersion curve of an integrated silicon-on-insulator coupled-cavity waveguide in a photonic crystal environment using a technique based on far-field imaging. We show that a chain of eight coupled cavities of a moderate Q ...
