  Microwave photonics (MWP) is an emerging field in which radio frequency (RF)
signals are generated, distributed, processed and analyzed using the strength
of photonic techniques. It is a technology that enables various functionalities
which are not feasible to achieve only in the microwave domain. A particular
aspect that recently gains significant interests is the use of photonic
integrated circuit (PIC) technology in the MWP field for enhanced
functionalities and robustness as well as the reduction of size, weight, cost
and power consumption. This article reviews the recent advances in this
emerging field which is dubbed as integrated microwave photonics. Key
integrated MWP technologies are reviewed and the prospective of the field is
discussed.
