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 ...
For the past couple of decades the desire to add more complexity to a computer chip, while simultaneously reducing the cost per bit, has been accommodated by down-scaling. This approach has been extremely successful in the past, but like all good things it ...
Thermo-optical and electro-optical (plasma dispersion) effects for silicon based integrated optical modulators are becoming attractive and effective solutions for telecommunications applications such as switching for programmable optical add-drop multiplex ...
We study the interaction of a mode propagating in a planar waveguide with a three dimensional rectangular defect (protrusion or notch) in the structure. The scattering by the defect disturbes the propagation of the mode and light is coupled out of the wave ...
Two-dimensional (2D) photonic crystals (PhCs) at near-infrared wavelengths are promising candidates for novel integrated optics applications. The main focus being on 'all PhC' monolithically integrated optical circuits. Because of well established fabricat ...
One of the most important parameters in characterization of integrated optical devices is precise determination of the effective cut-off wavelength of the fundamental and first-order modes, since this sets the exact region of single-mode operation. This pa ...
We experimentally investigate guided acoustic wave Brillouin scattering in several photonic crystal fibers by use of the so-called fiber loop mirror technique and show a completely different dynamics with respect to standard all-silica fibers. In addition ...
We demonstrate that an optical fibre current sensor can measure current over 500 kA with an accuracy of 0.2%. This level of accuracy has never previously been achieved using a traditional non-optical sensor ...
We present the infiltration of semiconductor photonic devices with organic materials. The infiltration procedures are described and validated. In particular, the optical properties of hybrid photonic crystal cavities are studied. ...
