- In the presentation, I discuss new approaches to frequency conversion of electromagnetic fields using optomechanical interaction. The main figure of merit we are trying to optimize is the transduction bandwidth. I show that the bandwidth can be enhanced by using spatially adiabatic state transfer in an array of conventional optomechanical transducers.
