“…Some special approaches are proposed to minimize the polarization-sensitivity of SOInanowire photonic integrated devices including multimode interference (MMI) couplers, MRRs, and AWG (de)multiplexers [95][96][97][98][99][100]. A general solution to eliminate the polarizationsensitivity of silicon photonic integrated devices is using the so-called polarization-diversity technology [101][102][103]. In Ref.…”

“…Polarization diversity technologies are not only essential for solving the polarization issues of SOI-nanowire PICs, but also the key for realizing the PDM technology. For such polarization diversity circuits, the polarizing beam splitter (PBS) and polarization rotator (PR) are the most important elements [101][102][103], which will be reviewed in the following section.…”

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.

“…In this approach, one only needs identical optical modulators and identical photodetectors working for one polarization, which make the system design simple and easy. Furthermore, one does not need any polarization rotator working for high-order modes (various polarization rotators currently available work only for the fundamental mode [5]). Note that the polarization separation/combination with higher-order modes is not easy because a conventional PBS can work for the fundamental modes only and is not available for the present case with multiple modes.…”

“…Therefore, onchip PMD technology can be realized conveniently to double the link capacity by using polarization handling devices including polarization beam splitters (PBSs) and polarization rotators. In recent years, people have developed various polarization handling devices based on different structures/materials (see e.g., our recent review on this [5]). In this paper we focus on the SDM technology, which has attracted intensive attention for long-haul optical fiber communications to improve the capacity by using multi-core [6] as well as multimode optical fibers or waveguides [7,8].…”

Abstract-Multimode spatial-division multiplexing (SDM) technology has attracted much attention for its potential to enhance the capacity of an optical-interconnect link with a single wavelength carrier. For a mode-multiplexed optical-interconnect link, the functional elements are quite different from the conventional ones as multiple modes are involved. In this paper we give a review and discussion on multimode photonic integrated devices for mode-multiplexed opticalinterconnects. Light propagation and mode conversion in tapered waveguides as well as bent waveguides are discussed first. Recent progress on mode converter-(de)multiplexers is then reviewed. The demands of some functional devices used for mode-multiplexed opticalinterconnects are also discussed. In particular, the fabrication tolerance is analyzed in detail for our hybrid demultiplexer, which enables mode-/polarization-division-(de)multiplexing simultaneously.

This article has been accepted for publication in a future issue of this journal, but has not been fully edited. Content may change prior to final publication. We propose and experimentally demonstrate a novel approach to implement a low loss, broadband and compact transverse electric (TE)-pass polarizer on a silicon-on-insulator (SOI) platform. The TE-polarizer utilizes a subwavelength grating (SWG) structure to engineer the waveguide equivalent material index. In this work, the SWG-based polarizer only supports its fundamental TE mode while the transverse magnetic (TM) mode is suppressed under the cut-off condition, i.e., the TM mode leaks from the waveguide with a low reflection. The simulations predict that the bandwidth to achieve a polarization extinction ratio (ER) of 35 dB exceeds 200 nm. Experimentally, the measured polarization ER is ~30 dB and the average insertion loss is 0.4 dB, in the wavelength range 1470 nm -1580 nm. The fabricated TE-polarizer has a compact length of 60 µm.
