In this letter we show the effect of rotation of two oscillators on the sensitivity performance of two SAW coupled oscillator sensor configuration. The dependence of synchronization frequencies on the frequency detuning between the two counter-rotating oscillators, the insertion loss and delay of the coupling SAW delay line are analysed. The sensitivity for SAW coupled counter-rotating oscillators...
We present an experimental and numerical study of the dynamics of a semiconductor laser subject to filtered optical feedbacks (FOFs) from two separate external cavities. Our results show that the inclusion of a second FOF introduces a rich control over the frequency of the dynamics. The period of frequency oscillations of the laser light is determined by the two time scales related to the feedback...
