Abstract

A compact optical delay line optoelectronic oscillator is designed to fit in a volume of less than 1 liter consists in a 1.55 μm wavelength laser, a modulator, an optical fiber acting as a delay line, a photodetector, a X-band microwave amplifier and a driving coupler. This oscillator is stable in terms of nominal delivered frequency. In addition, its elements are less sensitive to environmental and mechanical disturbances. Compactness is evaluated in terms of efficiency and the signal is characterized in terms of power delivered and stability of the nominal frequency. We rely on the measurement of phase noise carried out using a bench developed in the laboratory and we give an approximation of the specifications with an uncertainty of 1,5 dB at 2 σ for an output microwave signal calculated according a modern approach, by enriching the work done on the radio frequency or microwave signals.
