“…It has been realized that most photonic integrated devices are polarization dependent due to the birefringence of optical waveguides (as summarized in Table 2), which provides various ways to realize waveguide-type PBSs, including multimode interferometers (MMIs) [106][107][108][109][110], DCs [111][112][113][114][115][116][117][118], MZIs [119][120][121], photonic crystal (PhC) structures [122][123][124][125][126], AWGs [127], MRRs [128], etc. Among them, a DC structure is an attractive option for PBSs because of its structural simplicity.…”

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.

“…An important building block for network-on-chip architectures is the 2×2 crossbar switch, a device with two inputs and outputs whereas the optical routing is controlled by an electrical gate. A variety of photonic switches have been investigate such as those based on directional couplers (DC) [2][3][4], multimode interference (MMI) [5,6], ring resonators, Mach-Zehnder interferometers (MZI) [7,8] and photonic-crystal-based (PhC) structures [9][10][11]. While these approaches are able to reduce the footprint into the ten's of micrometer scale for instance by deploying high-Q ring resonators, they introduce other limitations relating to bandwidths (spectrally and temporally) and demand tighter fabrication tolerances for mode-coupled devices [12,13].…”

Abstract:We report on a three-waveguide electro-optic switch for compact photonic integrated circuits and data routing applications. The device features a plasmonic metal-oxide-semiconductor (MOS) mode for enhanced light-matter-interactions. The switching mechanism originates from a capacitor-like design where the refractive index of the active medium, indium-tin-oxide, is altered via shifting the plasma frequency due to carrier accumulation inside the waveguide-based MOS structure. This light manipulation mechanism controls the transmission direction of transverse magnetic polarized light into either a CROSS or BAR waveguide port. The extinction ratio of 18 (7) dB for the CROSS (BAR) state, respectively, is achieved via a gating voltage bias. The ultrafast broadband fJ/bit device allows for seamless integration with silicon-on-insulator platforms for low-cost manufacturing.

“…Various PBS's have been reported. The fabrication of the PBS based on an asymmetrical Y -Junction structure [1] or Mach-Zehnder interferometer (MZI) [2] requires complex processes such as photobleaching and poling.The PBS based on directional couplers [3] and conventional multimode interference (MMI) couplers [4] usually have a large size since the total length should be integer multiples of the coupling lengths for both polarizations. In recent years, photonic crystals (PhCs) [5][6][7][8] have been extensively investigated aiming at the realization of high efficient ultra-compact photonic components.…”

Abstract-We present the design and simulation of an ultra-compact polarization beam splitter (PBS) by combining a photonic crystal (PhC) multimode waveguide and an internal PhC section. The PhC multimode waveguide is designed to collect the powers reflected by or transmitted through the internal PhC structure which serves as a polarization sensitive scatterer. Plane wave expansion (PWE) method is used to calculate the band structure and the finite-difference timedomain (FDTD) method is employed to obtain the spectrum response. The simulation results show that the present design can give an ultracompact PBS with high extinction ratio over a broad bandwidth.
