“…2(d). Optical arbitrary waveform generation (OAWG) is widely applied in various fields, such as high speed optical communications [24], ultra-wideband signals [2], radar systems [25], all-optical signal processing including optical differentiator [26] and optical integrator [27,28]. Besides, the photonic-based high frequency microwave signal generation also shows great importance in application, since it is superior to the traditional methods in many aspects such as speed, bandwidth and power consumption, thanks to the absence of electronic bottleneck.…”

Microwave photonic systems have huge potential for both existing and future applications, including radar, radiofrequency sensing and modern wireless communications due to their distinct advantages in terms of ultra-wide bandwidth, flexible tunability, and immunity to electromagnetic interference. There is a strong research trend in microwave photonic systems towards integration and miniaturization, resulting in multiple radio frequency functions on a single chip which is both compact and light weight. Thus integrated microwave photonics has attracted a lot of attentions and achieves significant improvements in last ten years. In this paper, we will review some research progresses on silicon-based integrated microwave photonics in our group, including highly efficient micro heater on silicon photonic chip, chip-scale microwave waveform generation, on-chip true time delay, and microwave photonic processing and measurement. Our schemes are all fabricated on silicon-on-insulator chips and have advantages of compactness and capability to integrate with electronic units. These chips may motivate the great application potentials in silicon-based integrated microwave photonics.

“…Over the past few years, the emergence of optical computing has provided the possibility to break several limitations of conventional signal processors [6]. Such an EM-wave-based computing strategy avoids analog-to-digital conversion and allows ultra-high-speed massively parallel operations [7], which has been proven to have great potential in temporal integration and differentiation [8,9], Hilbert transformation [10], spatial differentiators [11], logic gate [12], and arbitrary waveform generation [13].…”

In this paper, a novel strategy based on a metasurface composed of simple and compact unit cells to achieve ultra-high-speed trigonometric operations under specific input values is theoretically and experimentally demonstrated. An electromagnetic wave (EM)-based optical diffractive neural network with only one hidden layer is physically built to perform four trigonometric operations (sine, cosine, tangent, and cotangent functions). Under the unique composite input mode strategy, the designed optical trigonometric operator responds to incident light source modes that represent different trigonometric operations and input values (within one period), and generates correct and clear calculated results in the output layer. Such a wave-based operation is implemented with specific input values, and the proposed concept work may offer breakthrough inspiration to achieve integrable optical computing devices and photonic signal processors with ultra-fast running speeds.
