| 11 | Laser sources for microwave to millimeter-wave applications [Invited]显示文摘We present several laser sources dedicated to advanced microwave photonic applications.A quantum-dash mode-locked laser delivering a high-power,ultra-stable pulse train is first described.We measure a linewidth below 300 kHz at a 4.3 GHz repetition rate for an output power above 300 mW and a pulse duration of 1.1 ps after compression,making this source ideal for microwave signal sampling applications.A widely tunable(5–110 GHz),monolithic millimeter-wave transceiver based on the integration of two semiconductor distributed feedback lasers,four amplifiers,and two high-speed uni-traveling carrier photodiodes is then presented,together with its application to the wireless transmission of data at 200 Mb∕s.A frequency-agile laser source dedicated to microwave signal processing is then described.It delivers arbitrary frequency sweeps over 20 GHz with high precision and high speed(above 400 GHz∕ms).Finally,we report on a low-noise(below 1 kHz linewidth),solid-state,dual-frequency laser source.It allows independent tuning of the two frequencies in the perspective of the implementation of a tunable optoelectronic oscillator based on a high-Q optical resonator. | Gaël Kervella Jeremy Maxin Mickael Faugeron Perrine Berger Hadrien Lanctuit Gregoire Pillet Loïc Morvan Frédéric van Dijk Daniel Dolfi | 2014 | Photonics Research2014，2，4： | 0 |
