Dynamic control of the speed of a light signal, based on stimulated Brillouin scattering in optical fibers, was theoretically studied and also experimentally demonstrated as the core object of this thesis. To date, slow light based on stimulated Brillouin ...
We propose the use of pulse Simplex-coding in distributed temperature sensors based on spontaneous Brillouin scattering. The analysis shows achieved performance improvement and the effect on stimulated Brillouin threshold, resulting in lower required input ...
A mathematical approach is presented that is based on coupled-mode theory (CMT); it is extended to infinite perfect photonic structures and combined with the supercell method for analysis of infinite photonic crystals with introduced point (0D) and linear ...
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 ...
We have recently demonstrated an ultrafast photonic crystal laser and cavity coupled laser array with modulation rates of 1THz at room temperature, a 20 GHz optical modulator with activation energies of 60 Q and a quantum dot photonic crystal laser with la ...
In this work we study from a theoretical point of view microcavities embedding organic materials featuring vibronic progressions. As already shown in seminal experiments, the presence of vibronic replicas largely enriches the physics of such systems with t ...
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. ...
Electrical and optical characterization has been performed on several superconducting single photon detectors (SSPDs) consisting of meanders made of ultrathin NbN films. The NbN films, with thickness ranging from 150 nm to 3 nm, were deposited by dc magnet ...
The optical study of single quantum dashes located inside a 2.5D photonic crystal structure is performed. The enhancement of the emission is observed for quantum dash in resonance with a slow Bloch mode. ...

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 ...
