Abstract :
This paper reports on microwave photonics design and characterization of optically-controlled MMIC oscillator. Microwave photoconductive switches (MPCS) design methodology under continuous, intensity-modulated and pulsed optical control has led to microwave predictions of an oscillating device in GaAs integrated technology, under these optical control formats. Microwave oscillations at a frequency of 5 GHz during 2 ns have been experimentally achieved thanks to device illumination using fs optical pulses at 80 MHz repetition frequency.
