We demonstrate that an ultrathin ridge (< lambda/10) can guide Bloch surface waves in a dielectric multilayer. The propagation and polarization properties of the guided modes are investigated with a multi-heterodyne scanning near-field optical microscope. ...

Effect of relaxation time on the performance of photonic crystal optical bistable switches based on Kerr nolinearity is discussed. This paper deals with optical pulses with the duration of about 50 ps. In such cases the steady state response of the optical ...

The main topic of this thesis is the fabrication and characterization of structures smaller than the wavelength of light, for operation in the visible or near infrared spectral range. In the first part of this thesis, the fabrication of periodic structures ...
Photonic and plasmonic interactions in multi-layered plasmonic crystals, formed by coupling nanohole-nanoparticle arrays, are investigated. The hybrid structure exhibits extraordinary optical transmission as in single layer nanohole arrays and supports Fab ...
A complete realization of an optically tunable true time delay, generated through the combination of a photonic RF phase shifter and a Brillouin slow light element is presented. Illustration through a dynamic microwave photonic filter is demonstrated. ...
The enhancement of the extraction efficiency in light emitting diodes (LEDs) through the use of photonic crystals (PhCs) requires a structure design that optimizes the interaction of the guided modes with the PhCs. The main optimization parameters are rela ...
Dynamic reconfiguration of a microwave photonic filter by tuning its basic delay based on stimulated Brillouin scattering-induced slow light and optical phase shift of the optical carrier is experimentally implemented. The measurements confirm that the fre ...
This paper presents helpful expressions predicting the filling time of gaseous species inside photonic crystal fibres. Based on the theory of diffusion, our gas-filling model can be applied to any given fibre geometry or length by calculating diffusion coe ...

This letter reports on high extraction efficiency light-emitting diodes (LEDs) based on embedded two-dimensional air-gap photonic crystals (PhCs). High refractive index contrast provided by the air gaps along with high interaction of the embedded PhCs with ...
We present a direct evidence of Bloch surface waves (BSWs) waveguiding on ultrathin polymeric ridges, supported by near-field measurements. It is demonstrated that near-infrared BSWs sustained by a silicon-based multilayer can be locally coupled and guided ...
