A simple and cost-effective technique for generating a flat, square-shaped multi-wavelength
optical comb with 42.6 GHz line spacing and over 0.5 THz of total bandwidth is presented. A …

We report the first demonstration of a monolithic optical-frequency comb generator. The
device is based on multisection quaternary/quaternary eight-quantum-well InP-InGaAsP …

All-optical signal processing is a powerful tool for the processing of communication signals
and optical network applications have been routinely considered since the inception of …

The THz spectral range is yet not fully exploited to its full potential due to the current
limitations in sources and detectors. To open the frequency range for applications, photonic …

The global traffic is experiencing an exponential growth due to the emerging bandwidth
hungry applications and the increase of the number of users, posing a severe challenge to …

We have developed a quantum dash (QDs) mode locked laser (MLL) using an asymmetrical
cladding for high frequencies microwave generation. The laser exhibits more than 400 mW …

Les peignes de fréquence optique sont aujourd'hui utilisés pour la métrologie ou la
génération d'impulsions ultra-courtes. Des solutions à base de lasers fibrés à verrouillage …
