“…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.

“…At present, optical communication is widely used in data centres, and the optical modules in data centres are developed from 10G/40G to 100G/400G or beyond [3][4][5][6][7]. And high-bandwidth optical modules require the perfectperformance optoelectronic device and the design of the package [8][9][10][11][12][13]. In optical interconnect systems, microring modulators (Microring modulator (MRM)), which have the advantages of smaller size and lower power consumption compared to the traditional Mach-Zender modulator, have attracted more and more researchers' attention [14][15][16][17][18][19][20].…”

“…In 1999 and 2004, Manfred and M.L. proposed a series of formulas for the calculation of MRMs performance parameters [9,10], which established a solid theoretical foundation for MRM design. But the formulas are difficult to be applied directly by designers in the actual design, because there are multiple parameters in the MRM design that interact with each other, which leads to the fact that the calculation of actual MRM parameters is extremely complex.…”

The microring modulator (MRM) is a small‐size and low‐power component, which is the potential for the next‐generation optical interconnection. By the theoretical analysis, increasing the electrical bandwidth, which is relevant to the cross section and the doping concentration of the doping region, is a better way to increase electro‐optical (EO) bandwidth. Therefore, a new doping profile of the PN depletion region with 4 doping concentration levels is introduced considering the electrical bandwidth. Based on the new doping profile, the MRM with the 160 μm length and the 0.33 and 0.2 μm coupling space are determined considering the trade‐off between the EO bandwidth, quality factor (Q), extinction ratio, area of MRM, and power consumption. Moreover, the MRM is characterised and is applied in a wavelength division multiplexing transmitter. By the measurement, the transmitter with the designed MRM could transmit PAM4 signal at 52 Gbps rate, which indicates the MRM could be potential for the 50 Gbps/ch optical interconnection.
