Linear micromirror array for broadband femtosecond pulse shaping in phase and amplitude

We are developing a linear array of micromirrors designed for optical, femtosecond laser pulse shaping. It is a bulkmicromachined device, capable of retarding or diminishing certain laser frequencies in order to perform phase and amplitude modulation withi ...

Governing the speed of a light signal in optical fibers

Sang Hoon Chin

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 ...

Large linear micromirror array for UV femtosecond laser pulse shaping

Nico de Rooij, Jonathan Leon Wolf

We are fabricating a bulk-micromachined micromirror device for laser pulse shaping applications on femtosecond time scales. An array of micromirrors is used to individually retard or diminish certain laser frequencies spanning from the UV to the near-infra ...

On the Combination of Auditory and Modulation Frequency Channels for ASR applications

Hynek Hermansky, Fabio Valente

This paper investigates the combination of evidence coming from different frequency channels obtained filtering the speech signal at different auditory and modulation frequencies. In our previous work \cite{icassp2008} ...

An automatic pulse alignment method for slope controlled super-regenerative receiver systems

Catherine Dehollain, Michel Declercq

Recently there is an increase in interest for using super-regenerative receivers for pulse based communication systems. To receive a pulse using the super-regenerative architecture the pulse needs to be aligned with the zero crossing of the damping co-effi ...

Efficient error correction solutions for OFDM based digital video

Mauro Lattuada

The robustness of the delivery of digital compressed video streams has always been one of the main topic of the standardization bodies to assure the Quality of the Service (QoS). The MPEG standard which is nowadays the reference for digital television defi ...

Grating formation in step flow heterogeneous growth and wavelength selection induced by confinement

Klaus Kern, Harald Brune

Based on kinetic Monte Carlo simulations, we show that modulated wires and island gratings can be formed at vicinal surfaces. The modulation (grating) wavelength along the steps can be tailored by external conditions (coverage and temperature) and intrinsi ...
