Integrated Microwave Photonics

Microwave photonics refers to the generation, processing, distribution, and measurement of microwave signals using photonic components and techniques.  Key advantages of microwave photonics are ultra-wide bandwidth and flexible reconfiguration in of optical processing.

Principles of microwave photonics

We explore the use of low-loss photonic integrated circuits in RF- microwave photonic systems. By harnessing linear and nonlinear optical interactions in these circuits, advanced functionalities including filtering, true-time delay, phase shifting, and pulse shaping have been demonstrated.
