“…One example is the ringassisted MZI (RAMZI) structure, depicted in figure 14(a), that relies on cancellation of the opposing non-linear responses that are inherent to MZI and ring resonators; SFDRs of up to 99 dB Hz 2/3 at 10 GHz have been achieved [297][298][299]. Other design approaches attempt to cancel out the IMD3, such as the dual-parallel-MZIs that achieve SFDRs of up to 114 dB Hz 2/3 at 10 GHz [300][301][302] depicted in figure 14(b), and the FLAME configuration mentioned earlier that attains SFDRs of up to 120 dB Hz 2/3 at 10 GHz [274], depicted in figure 14(c).…”

“…Thirdly, ring resonators with a high Q-value are limited in operation frequency due to photon lifetime, rather than RC time constants or carrier dynamics. This can be circumvented, for instance, by using the dual-injection method of the FLAME ring modulator introduced in [274] or by using the FSR coupling as described in [275]. Finally, fabrication complexity should be considered along with the required number of driving signals, considering that electrical probing and wiring become complex and expensive at mm-wave frequencies.…”

Technological innovation with millimeter waves (mm waves), signals having carrier frequencies between 30 and 300 GHz, has become an increasingly important research field. While it is challenging to generate and distribute these high frequency signals using all-electronic means, photonic techniques that transfer the signals to the optical domain for processing can alleviate several of the issues that plague electronic components. By realizing optical signal processing in a photonic integrated circuit (PIC), one can considerably improve the performance, footprint, cost, weight, and energy efficiency of photonics-based mm-wave technologies. In this article, we detail the applications that rely on mm-wave generation and review the requirements for photonics-based technologies to achieve this functionality. We give an overview of the different PIC platforms, with a particular focus on hybrid silicon photonics, and detail how the performance of two key components in the generation of mm waves, photodetectors and modulators, can be optimized in these platforms. Finally, we discuss the potential of hybrid silicon photonics for extending mm-wave generation towards the THz domain and provide an outlook on whether these mm-wave applications will be a new milestone in the evolution of hybrid silicon photonics.

Photonic integrated circuits (PICs) have recently attracted extensive attention in advanced photonic signal processing to meet the ever-increasing demands on high-speed and ultracompact data signal management. However, programmable and multitask photonic signal processing is still full of challenges, especially the scalable photonic integration solution. Here, we design, fabricate, and demonstrate a mesh-structure-enabled programmable multitask photonic signal processor on a silicon chip. It relies on a scalable 2D mesh structure network with a number of hexagonal unit cells formed by building blocks of tunable Mach–Zehnder interferometers (MZIs). We study several simple and complex optical filtering functions using configured single ring resonator, cascaded ring resonators, ring-assisted MZI, cascaded MZIs, reconfigurable and tunable comb filter and (de)interleaver, and double-injection ring resonators. For the proof-of-concept demonstration of on-chip programmable multitask photonic signal processing, a monolithically integrated silicon chip with four hexagonal unit cells is fabricated with greatly reduced geometric dimension. By appropriately adjusting the thermo-optic phase shifters of MZIs, versatile programmable multitask photonic signal processing functions are demonstrated in the experiment with impressive performance, including single ring resonator, cascaded ring resonators, asymmetric MZI, ring-assisted MZI, optical delay line, multiport router, and N × N optical switch. In particular, we also demonstrate the optical interference unit (OIU)-enabled self-configurable router and switch and their practical applications in fiber-optic communication systems. The demonstrations may open up new perspectives for on-chip solutions to ultracompact, reconfigurable, programmable, and multifunctional data signal management in advanced optical communication networks.

Silicon photonics has found a profound place among emerging technologies in the past few decades due to several advantages. Due to a series of breakthroughs and increased funding from private and government sectors, the development of silicon photonics has accelerated especially starting from the two years 2004–2005 with a persisting and ever‐growing momentum. Among various components, the silicon photonic filters that selectively pass or block particular wavelengths with a finite bandwidth have found particular interest as they are useful in signal processing in different fields ranging from optical communication to microwave photonics and quantum photonics. Herein, a comprehensive review of silicon photonic filters focusing on the four most commonly used architectures, such as microring resonators, waveguide Bragg grating, Mach–Zehnder interferometers, and arrayed waveguide grating, encapsulating basics, and guidelines, in terms of simulating tools and topologies, of realizing reconfigurable and high‐performing filters for several applications, is provided. The novelty of this review relies on the fact that it summarizes these filter architectures covering a broad range of applications concisely and constructively and includes the basics, growth, and future trends, providing a clear understanding and importance of silicon photonic filters from research to commercialization perspective.
