| Popis: | International audience; We propose in this paper to come back to the starting conditions of optoelectronic oscillators and in particular with regard to the Barkhausen conditions. The context is first of all the anniversary of the hundred years since the discovery of We propose in this paper to come back to the starting conditions of optoelectronic oscillators and in particular with regard to the Barkhausen conditions. The context is first of all the anniversary of the hundred years since the discovery of oscillations conditions and their optimization by Heinrich Barkhausen, whose principles we recall [1]. We then give through the study of an example, how these conditions are relevant to optimize the start of the oscillation. The type of optoelectronic oscillator chosen for this study is an optoelectronic oscillator based on optical delay lines. The optical signal carrier wavelength is 1.55 μm, the typical oscillation frequency is 10 GHz [2 – 5]. It is all the more interesting to approach this subject in the context of the centenary of this discovery, which we can see how the advances made possible by H. Barkhausen are essential and still relevant today |
