“…[3] Further multiplexing technologies have been developed, e.g., space-division-multiplexing (SDM) with multiple cores, [4] modedivision-multiplexing (MDM) with multiple guided-modes, [9] and polarizationdivision multiplexing (PDM) with dual polarizations. [10,11] These additional multiplexing approaches help not only to save the physical space but can also reduce the cost of the system. Furthermore, these multiplexing approaches have independent degrees of freedom and can be used simultaneously to form a hybrid multiplexing technology, so that the capacity of an optical communication system increases even to Peta-bit/s.…”

A dual-polarization 10-channel mode (de)multiplexer is proposed and realized with cascaded dual-core adiabatic tapers on a silicon-on-insulator (SOI) platform. The mode demultiplexer has a 2.3 μm-wide multimode bus waveguide, which supports six mode-channels of TE polarization and four mode-channels of TM polarization. These ten mode-channels are (de)multiplexed with five cascaded dual-core adiabatic tapers based on SOI nanowires. The widths for these dual-cores are chosen optimally according to the dispersion curves of the dual-core SOI nanowire, so that the desired highest-order modes of TE-and TM-polarizations are extracted simultaneously. These two extracted mode-channels are coupled very efficiently to the fundamental modes of TE-and TM-polarizations (TE 0 and TM 0 ) in the narrow waveguide, respectively, which are then separated by using a polarization beam splitter based on bent directional couplers. A chip consisting of a pair of 10-channel mode (de)multiplexers is fabricated and then tested with data transmission of 30Gbps/channel. The measurement results show that all TM-and TE mode-channels have low crosstalks (-15ß-25 dB) and low excess losses (0.2ß1.8 dB) over a broad wavelength band of ß90 nm, which makes it WDM (wavelength-division-multiplexing)-compatible and thus suitable for high capacity on-chip optical interconnects.

“…Examples of devices for these applications include dual-polarization QPSK coherent receiver and transmitter silicon PICs demonstrated at 112 Gb/s [20][21][22]. With its high integration level on a single chip, chip-scale WDM modulator and receiver silicon PICs have been demonstrated [23,24].…”

“…Bell Labs has reported various PICs, indicating that silicon photonics could find more utility in photonic integration than in discrete devices. At receiver side, the demonstrated PICs include various WDM receivers [23,[49][50][51], dual-polarization coherent receivers based on novel gratings [21,52] and on-chip polarization rotators [22], dual-polarization differential-QPSK (DQPSK) receivers [53], and spacedivision multiplexing (SDM) receivers [54]. At transmitter side, the demonstrated PICs include 10 × 25 Gb/s dense WDM (DWDM) modulators [24], dual-polarization coherent modulators based on silicon MZMs [20], QPSK modulators based on microring modulators [55,56], and DWDM 10-channel variable optical attenuators with multiplexers (VOA-MUX) [57].…”

“…The TE (or TM) components of signal and LO are mixed with a 90° optical hybrid, balance-detected by four photo detectors and amplified by two TIAs, which produce both in-phase and quadrature information of the signal. Such coherent receivers have been realized in discrete component formats, hybrid planar lightwave circuits with photo detectors [59][60][61], InP PICs [62][63][64], and silicon PICs [21,22]. Except silicon PICs, polarization diversity or dual-polarization coherent receivers are realized by the use of micro-optical free-space polarization rotators and beam splitters.…”

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.
