Integrated microwave photonics

Abstract

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.

Integrated microwave photonics for 5G

“…Integrated microwave photonics (IMWP) is a novel field in which the fast-paced progress in integrated optics is harnessed to provide breakthrough performances in well-established microwave photonic processing functions, which are traditionally realized using discrete optoelectronic components [1]. A field where IMWP is expected to have a strong impact is the one of phased array antennas.…”

Optical injection locking of monolithically integrated photonic source for generation of high purity signals above 100 GHz

“…The generation and processing of signals in the microwave, mm-wave and THz frequency ranges based on photonic solutions has been under extensive investigation [1] [2] [3]. This is driven by the numerous advantages that photonics can offer, as compared with electronicsbased solutions, as well as by increasing interest in high frequency generation caused by the anticipated spectrum crunch [4].…”

Integrated Microwave Photonics for Wideband Signal Processing

“…Bringing together the worlds of radiofrequency (RF) engineering and optoelectronics, the field of MWP has recently attracted great interest from both the research and the commercial communities where its importance has been identified in emerging applications including medical imaging, future 5G networks, and subterahertz systems. It offers the unique abilities to enable key functionalities in microwave systems such as filtering, arbitrary waveform generation, frequency up/down conversion and instantaneous measurement that are either complex or even not directly possible in the radiofrequency domain [1][2][3][4][5][6][7][8][9]. As the role of MWP develops from niche to widespread applications, it becomes important to replace systems that rely exclusively on discrete optoelectronic devices and fiber-based components.…”
