“…Moreover, from the system level, because of the CMOS compatibility and low-cost mass production of the silicon modulator, the cost can be further reduced by large-scale silicon modulator deployment in access. For ONU and OLT in the near future, integrating multiple devices, such as laser, modulator, PD, passive devices, and electronic circuits, onto a chip can significantly reduce the cost and power consumption [40]- [41], which will greatly benefit the operators and end users.…”

A novel maximum-ratio combined receiver (MRC-RX) is proposed and demonstrated through a proof-of-concept experiment, conducted to mitigate the system performance degradation caused by the low linearity of the silicon modulator when deployed in passive optical network (PON)-based access. By employing the proposed MRC-RX, an optimized receiver sensitivity is achieved, which enables the mitigation of the performance degradation induced by the silicon modulator, and a more reliable transmission in both cases of low and high received power. In the proof-of-concept experiment, at a bit error rate of 1.0×10-4 , the receiver sensitivity of the MRC-RX was improved by 3.5 dB and 6.7 dB compared with the lite coherent receiver (lite CO-RX) and direct detection receiver (DD-RX), respectively. Compared with a system employing a commercial lithium niobate (LiNbO3) modulator, a maximum improvement of ~5.6 dB in the receiver sensitivity was obtained for the MRC-RX in the silicon modulator system. Thus, the system performance degradation caused by the low linearity of the silicon modulator can be effectively reduced by employing the MRC-RX. The proposed method makes sense to the building of next generation high reliable photonics integrated access by employing silicon modulators.

“…To summarize, making specialized ICs is one of the top promising solution for the efficient computing. In accordance with that, the foundry companies would diversify their process technology instead of scaling it down, for example the Global Foundries 45nm CLO process, which is specialized to silicon photonics [32].…”

Due to explosive increase of digital data creation, demand on advancement of computing capability is ever increasing. However, the legacy approaches that we have used for continuous improvement of three elements of computer (process, memory, and interconnect) have started facing limit, and therefore they are not as effective as they used to be and are also expected to reach the end in the near future. Evidently, it is a big challenge for computer hardware industry. However, at the same time it also provides great opportunities to hardware design industry to develop novel technologies and to take leadership away from incumbents. This paper reviews the technical challenges that today's computing systems are facing and introduces potential directions for continuous advancement of computing capability, and discusses where computer hardware designers find good opportunities to contribute.

This invited paper reviews the progress of silicon-germanium (SiGe) bipolar-complementary metal-oxidesemiconductor (BiCMOS) technology-based integrated circuits (ICs) during the last two decades. Focus is set on various transceiver (TRX) realizations in the millimeter-wave range from 60 GHz and at terahertz (THz) frequencies above 300 GHz. This article discusses the development of SiGe technologies and ICs with the latter focusing on the commercially most important applications of radar and beyond 5G wireless communications. A variety of examples ranging from 77-GHz automotive radar to THz sensing as well as the beginnings of 60-GHz wireless communication up to THz chipsets for 100-Gb/s data transmission are recapitulated. This article closes with an outlook on emerging fields of research for future advancement of SiGe TRX performance.
