Abstract In optical networks for telecom and datacom, an unprecedented energy efficient system is demanded since the amount of data traffic is rapidly increasing while a significant improvement of the energy efficiency in electronics devices such as switch ASICs is no longer expected. To overcome the energy constraints, introduction of energy-efficient optical circuit switching (OCS) to the conventional electrical packet switching network is considered. The energy consumption of the OCS is almost independent of the bandwidth because the transparent optical path with no optical-to-electrical/electrical-to-optical signal conversion supports an ultrawide bandwidth of highly multiplexed optical signals. In the OCS, high-speed and large-port-count optical switches are essential. We have been working on optical switches based on CMOS-compatible silicon photonics that offer fast switching, compactness, low power consumption, and low cost. By using our 45-nm CMOS process, we have recently demonstrated a low loss 32 × 32 silicon photonics switch and its performance improvements of wide operation bandwidth, polarization-independent operation, and so forth. In this paper, we review the recent progress of our silicon photonics switches. We discuss the importance of the silicon photonics switches for a sustainable optical network with a comparison of other switching technologies and explain comprehensively how our numerous achievements are advanced and related to each other.

基于 45 纳米 CMOS 技术的大规模硅光子开关

摘要 在用于电信和数据通信的光网络中,由于数据流量正在迅速增加,而开关 ASIC 等电子设备的能效不再有望显着提高,因此需要一种前所未有的节能系统。为了克服能量限制,考虑将节能光电路交换 (OCS) 引入传统的电包交换网络。OCS的能耗几乎与带宽无关,因为没有光电/电光信号转换的透明光路支持高度复用光信号的超宽带宽。在 OCS 中,高速和大端口数的光开关是必不可少的。我们一直致力于基于 CMOS 兼容硅光子学的光开关,这些光开关提供快速开关、紧凑、低功耗和低成本。通过使用我们的 45 纳米 CMOS 工艺,我们最近展示了一种低损耗 32 × 32 硅光子开关及其在宽工作带宽、偏振无关工作等方面的性能改进。在本文中,我们回顾了我们硅光子开关的最新进展。我们讨论了硅光子开关对于可持续光网络的重要性,并与其他开关技术进行了比较,并全面解释了我们的众多成就是如何取得进步和相互关联的。我们最近展示了一种低损耗 32 × 32 硅光子开关及其在宽工作带宽、偏振无关工作等方面的性能改进。在本文中,我们回顾了我们硅光子开关的最新进展。我们讨论了硅光子开关对于可持续光网络的重要性,并与其他开关技术进行了比较,并全面解释了我们的众多成就是如何取得进步和相互关联的。我们最近展示了一种低损耗 32 × 32 硅光子开关及其在宽工作带宽、偏振无关工作等方面的性能改进。在本文中,我们回顾了我们硅光子开关的最新进展。我们讨论了硅光子开关对于可持续光网络的重要性,并与其他开关技术进行了比较,并全面解释了我们的众多成就是如何取得进步和相互关联的。
