In this paper, we present a nano-quantum photonic approach for the calculation of normal dispersion phenomena in organic crystals such as N-(4-nitrophenyl)-L-prolinol(NPP). We assume that a laser beam consists of a flow of energetic particles that interact ...
Photonic crystals are periodic dielectric structures having periodicity of the order of the wavelength. Consequently, they offer the ability to control the propagation of electromagnetic waves in a similar way as the periodic potential aspects the electron ...

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 ...
By integrating soft-lithography-based nanofluidics with silicon nanophotonics, we demonstrate dynamic, liquid-based addressing and high Δn/n (∼0.1) refractive index modulation of individual features within photonic structures at subwavelength length scales ...

The optical tuning of InP-based planar photonic crystals (PhCs) infiltrated with a photo-responsive liquid crystal system is presented. Photo-induced phase transitions of a liquid crystal blend doped with azobenzene molecules are used to tune the optical r ...
We have recently demonstrated a number of functional photonic crystals devices and circuits, including an ultrafast, room-temperature, low threshold, nanocavity laser with the direct modulation speed approaching 1THz, an all-optical switch controlled with ...
Deterministic integration of site-controlled InGaAs/GaAs quantum dots (QDs) with photonic crystal cavities is demonstrated. Fine adjustment of QD position (within similar to 10nm) and emission energy (few meV) allows construction of coupled QD systems. (C) ...

The field of photonic crystals is a rapidly developing branch of modern optics. Photonic crystals are believed to be the cornerstone for a wide range of new photonic devices controlling the confinement and propagation of light. These artificial structures ...
Efficiency and speed of photonic crystal lasers are improved by passivating InGaAs/GaAs membranes using (NH(4))S treatment. Lasers show five-fold reduction in nonradiative surface recombination rate, resulting in four-fold reduction in threshold and room-t ...
