Optomechanical microwave oscillators

Optomechanical interaction in optical dielectric cavities can be used to generate high-purity microwave tones, giving rise to optomechanical microwave oscillators. Here, we introduce the main properties of these devices, which can be implemented in photonic integrated chips, and envisage its deployment in the mid-term in microwave photonics applications.

Frequency and temperature control for complex system engineering in optoelectronics and electronics: an overview

To take advantage of the physical principles of determining parameters, such as frequency stability, noise and also alignment of optical signals, it is necessary to control complex systems. This work allows explaining it through various concrete cases such as the determination of phase noise of microwave oscillators, the control of the temperature of the manufacturing process of optical components. We also discuss the estimation of the uncertainty associated with the measurement results, as it is fundamental to control the error range.
