Analysis of brillouin-based distributed fiber sensors using optical pulse coding

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 ...

1-to-40 Channel Multicasting in Wideband Parametric Amplifier

Camille Sophie Brès

All optical multicasting using one-pump modulated parametric optical amplifier is reported. For a 10 Gb/s NRZ system, 1:40 multicasting is demonstrated with less than 0.5 dB power penalty and minimum 12.5 dB conversion efficiency. ...

Optical parametric generation in periodically poled KTiOP O4 via extended phase matching

Demetri Psaltis, Ye Pu

We report an experimental demonstration of optical parametric generation in a periodically poled KTiOP O4 crystal based on the principle of mirrorless optical parametric oscillation. A femtosecond pump pulse spectrally centered at 792 nm from a Ti:sapphire ...

Coherence properties of microcavity polaritons

Stefan Kundermann

This thesis presents the coherence properties of polaritons in semiconductor microcavities. Semiconductor microcavities are microstructures in which the exciton ground state of a semiconductor quantum well is coupled to a photonic mode of a microresonator. ...

EPFL2006

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 ...

Tunable microcavities in planar photonic crystals

Hans Peter Herzig, Iwan Märki

Micro- and nano-optical structures offer the possibility to control light on a wavelength scale. This allows further miniaturization of integrated optical circuits. Planar photonic crystal waveguides and microcavities are considered basic building blocks f ...

Advanced trends in nonlinear optics applied to distributed optical-fibre sensors

Dario Alasia

The distributed optical-fibre sensors based on the properties of Brillouin scattering is the central object of this thesis. In the past decade, optical fibres have gained a large interest as sensors: attractive solutions based on the non-linear stimulated ...

Etude et réalisation de cristaux photoniques pour l'optique intégrée

Benoît Lombardet

Photonic crystals are periodic dielectric structures, where the periodicity varies on the wavelength scale. Analogous to electrons in semiconductors, the photon propagation can be described using a band structure in which transmission bands are separated b ...

Experimental and numerical investigation of two-dimensional photonic crystals for application in integrated optics

David Leuenberger

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 ...

Practical and theoretical modal analysis of photonic ctystal waveguides

Hans Peter Herzig

A stage-by-stage analysis of light propagation around a 90° corner in a two-dimensional photonic crystal waveguide was discussed. The coupling efficiency between the conventional ridge waveguide and the photonic crystal waveguide was quantified using a ser ...
