We theoretically compute the coupling constant C between two emission modes of an extended cavity laser with a multiple quantum-well active layer. We use an optimized Monte Carlo model based on the Markov chain that describes the elementary events of carriers and photons over time. This model allows us to evaluate the influence on C of the...

Nous présentons un réseau d'antennes à excitation photonique et à commutation de faisceau pour des liaisons sans fil en bande E. Le réseau d'antennes se compose de deux sous-réseaux de patchs empilés servant de source primaire à une lentille en polytétrafluoroéthylène (PTFE) ; une photodiode alimente chaque sous-réseau. La lentille...

Nous avons conçu et construit un système optique de synthèse d'ondes hyperfréquences, millimétriques et submillimétriques à très bas bruit de phase. Les résultats préliminaires montrent une densité spectrale de bruit de phase à 10 kHz de la porteuse d'une onde à 9 GHz limitée par l'appareil de mesure. Pour les bruits plus près de la porteuse,...

We report on the design of an ultra stable microwave/THz oscillator and on the realization and the characterization of its laser source. The tunable oscillator is expected to show below -150 dB rad2/Hz phase instability at an offset frequency of 10 kHz for a 30 GHz carrier frequency, as well as 18 GHz, 100 GHz, 400 GHz and 1 THz carrier frequencies.
