“…In this paper, we propose a PSR on the silicon-on-insulator (SOI) platform based on the mode evolution [11][12][13] in a partially etched grating-assisted coupling system that operates under mechanism different from the previous works [5][6][7][8][9][10]. The device is compatible with the metal back-end of line process with high fabrication tolerance.…”

“…SOI-nanowire PRs have also been demonstrated with modified waveguide structures [149] and a 40 μm-long silicon PR based on mode evolution was demonstrated in Ref. [150], for which the fabrication is relatively easy because only a regular double-etching process is needed.…”

An effective solution to enhance the capacity of an optical-interconnect link is utilizing advanced multiplexing technologies, like wavelength-division-multiplexing (WDM), polarization-division multiplexing (PDM), spatial-division multiplexing (SDM), bi-directional multiplexing, etc. On-chip (de)multiplexers are necessary as key components for realizing these multiplexing systems and they are desired to have small footprints due to the limited physical space for on-chip optical interconnects. As silicon photonics has provided a very attractive platform to build ultrasmall photonic integrated devices with CMOS-compatible processes, in this paper we focus on the discussion of silicon-based (de)multiplexers, including WDM filters, PDM devices, and SDM devices. The demand of devices to realize a hybrid multiplexing technology (combining WDM, PDM and SDM) as well as a bidirectional multiplexing technologies are also discussed to achieve Peta-bit optical interconnects.

“…As discussed in Section 1, high-index-contrast silicon waveguides allow relatively easier design of polarization rotators and PBCs compared with other photonic technologies, since the waveguide modes are inherently hybrid modes and also the modal index/field can be controlled by the core size. Various silicon polarization rotators have been reported with high performance [10][11][12][13][14]. Both dual-layer and single-layer waveguide structures can be employed.…”

“…In addition, because of the large difference between waveguide width and height, submicron silicon waveguides could have a large index difference between the transverse-electrical (TE) and transverse-magnetic (TM) modes. This large birefringence can be used to make very compact and efficient polarization splitters and polarization rotators [10][11][12][13][14], which are ideal for constructing polarization-diversified photonic integrated circuits (PICs).…”

Silicon photonic devices and integrated circuits have undergone rapid and significant progresses during the last decade, transitioning from research topics in universities to product development in corporations. Silicon photonics is anticipated to be a disruptive optical technology for data communications, with applications such as intra-chip interconnects, short-reach communications in datacenters and supercomputers, and long-haul optical transmissions. Bell Labs, as the research organization of Alcatel-Lucent, a network system vendor, has an optimal position to identify the full potential of silicon photonics both in the applications and in its technical merits. Additionally it has demonstrated novel and improved high-performance optical devices, and implemented multi-function photonic integrated circuits to fulfill various communication applications. In this paper, we review our silicon photonic programs and main achievements during recent years. For devices, we review highperformance single-drive push-pull silicon Mach-Zehnder modulators, hybrid silicon/III-V lasers and silicon nitrideassisted polarization rotators. For photonic circuits, we review silicon/silicon nitride integration platforms to implement wavelength-division multiplexing receivers and transmitters. In addition, we show silicon photonic circuits are well suited for dual-polarization optical coherent transmitters and receivers, geared for advanced modulation formats. We also discuss various applications in the field of communication which may benefit from implementation in silicon photonics.
