“…This L!JL FGL EOY'T bcp approach has drawbacks such as electromagnetic interference (EMI) and frequency dependent losses. An interesting approach to process the millimeter-wave signal involves the use of photonics technology and especially fiber and integrated optics devices and circuits to perform the required signal processing tasks of millimeter-wave signals conveyed by an optical carrier directly in the optical domain [3].…”

Passive millimeter-wave imaging is attractive due to the ability to obtain images in low-visibility conditions. In this paper, a passive millimeter-wave imaging method using photonic processing is presented. The principle of the millimeter-wave photonic signal processing method is described. The relationship between the signal conversion gain and the component parameters is discussed. The noise characteristic of this detection method is analyzed. A millimeterwave radiometer using photonic processing is presented in this paper. A passive millimeter-wave scanning imaging system using this processing method was implemented. The imaging experiment results show that this imaging method is effective.

“…At the same time, they require devices that are small, lightweight, and low-power, exhibiting large tunability and strong immunity to electromagnetic interference. Integrated microwave photonics [4][5][6][7], an emerging technology combining RF engineering and integrated photonics, has the potential to satisfy these needs. Harnessing the large bandwidth and tunability uniquely offered by photonic devices, it enables wideband, flexible front-end analog solutions to precede digital signal processors that are currently limited to several gigahertz (GHz) analog bandwidths [8].…”

Integrated microwave photonics, an emerging technology combining radio frequency (RF) engineering and integrated photonics, has great potential to be adopted for wideband analog processing applications. However, it has been a challenge to provide photonic integrated circuits with equal levels of function flexibility as compared with their electronic counterparts. Here, we introduce a disruptive approach to tackle this need, which is analogous to an electronic field-programmable gate array. We use a grid of tunable Mach-Zehnder couplers interconnected in a two-dimensional mesh network, each working as a photonic processing unit. Such a device is able to be programmed into many different circuit topologies and thereby provide a diversity of functions. This paper provides, to the best of our knowledge, the first ever demonstration of this concept and shows that a programmable chip with a free spectral range of 14 GHz enables RF filters featuring continuous, over-two-octave frequency coverage, i.e., 1.6-6 GHz, and variable passband shaping ranging from a 55 dB extinction notch filter to a 1.6 GHz bandwidth flat-top filter.

“…Microwave photonics (MWP) is a multidisciplinary research discipline which bridges the photonics and microwave engineering worlds and investigates the handling of analog microwave signals using photonic devices and technologies for microwave applications, most prominently in telecommunications and sensing systems (the term microwave is used freely throughout the literature to designate either RF, microwave, or millimeter-wave signals) [1][2][3][4][5][6][7][8][9]. This emerging field has driven growing interest over the last three decades, mostly after the groundbreaking realization of the potential of optical links for the transmission of microwave signals in the 1990s [10][11][12].…”

Multitude applications of photonic devices and technologies for the generation and manipulation of arbitrary and random microwave waveforms, at unprecedented processing speeds, have been proposed in the literature over the past three decades. This class of photonic applications for microwave engineering is known as microwave photonics (MWP). The vast capabilities of MWP have allowed the realization of key functionalities which are either highly complex or simply not possible in the microwave domain alone. Recently, this growing field has adopted the integrated photonics technologies to develop microwave photonic systems with enhanced robustness as well as with a significant reduction of size, cost, weight, and power consumption. In particular, silicon photonics technology is of great interest for this aim as it offers outstanding possibilities for integration of highly-complex active and passive photonic devices, permitting monolithic integration of MWP with high-speed silicon electronics. In this article, we present a review of recent work on MWP functions developed on the silicon platform. We particularly focus on newly reported designs for signal modulation, arbitrary waveform generation, filtering, true-time delay, phase shifting, beam steering, and frequency measurement.
