Electromagnetic micro-transducers have been utilized in a number of distinct applications in recent years due, in large part, to their scalability, low power consumption, self-sensing capabilities and ease of integration with external hardware. In the present work, the highly non-linear dynamic behavior of a new class of parametrically excited, electromagnetically actuated microcantilevers is e...

A general parametrically and externally excited mechanical system is considered. The main attention is focused on the dynamical properties of local bifurcations as well as global bifurcations including homoclinic and heteroclinic bifurcations. In particular, degenerate bifurcations of codimension 3 are studied in detail. The original mechanical system is first transformed to averaged equations ...

the modulation response, relative intensity noise and frequency noise characteristics of qd lasers are investigated theoretically, in presence of an additional optical pumping. it is revealed that the modulation response of qd laser enhances under additional optical beam. by small signal analysis of the carriers' and photons' rates, it is proposed that by injecting excess carriers to ...
