Mode locked lasers for microwave photonics applications

We present different architectures of mode-locked lasers based on semiconductor devices for different applications of interest for microwave photonics like high frequency signal generation, low phase noise oscillators or high speed analogue signal sampling. For these applications we demonstrate both monolithic Fabry-Perot cavities and also external cavities using semiconductor optical amplifiers. Emission wavelength are for most of demonstrations at 1.5 μm but there are also demonstrations at 0.8 μm of interest for high speed sampling when associated with low temperature grown gallium arsenide photoswitches.
