“…Such polarization dependences have been one of the major challenges for SOI microphotonic devices because the polarization state may change randomly over an optical fiber link, making SOI microphotonic devices incompatible with optical processing functionalities. It is possible to design polarization insensitive SOI ridge waveguides under certain requirements of the waveguide dimensions [3,4]. However such requirements also limit the design of optical components and the optical confinement, hence the device footprint may be sacrificed as well.…”

A polarization splitter and rotator (PSR) based on a tapered directional coupler with relaxed fabrication tolerance is proposed and demonstrated on the silicon-on-insulator platform. The device is simply constructed by parallel-coupling a narrow silicon waveguide with a linearly tapered wider waveguide. Compared to previously reported PSRs based on a normal directional coupler, which suffer from stringent requirements on the accuracy of the narrow waveguide width, the introduced tapered structure of the wide waveguide can be used to compensate the fabrication errors of the narrow waveguide. In addition, only a single step of exposure and etching is needed for the fabrication of the device. Similar high conversion efficiencies are experimentally demonstrated for a narrow waveguide width deviation of 14 nm with large tolerance to the coupler length.

“…For fiber-related applications, polarization-insensitive PICs are usually needed. Theoretically speaking, it is possible to make SOI nanowires non-birefringent by optimizing the waveguide dimensions, like those demonstrated for large SOI ridge waveguides [90][91][92][93][94]. However, it is very hard to achieve non-birefringent SOI nanowires experimentally because of the stringent fabrication tolerance.…”

Silicon-based on-chip multiplexing technologies and devices for Peta-bit optical interconnects

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.

This is the accepted version of the paper.This version of the publication may differ from the final published version. Abstract: A gold-coated ormocomp waveguide is studied for it to be used for refractive index sensing applications. The ormocomp waveguide is fabricated using the nanoimprint method with width and height of 10 µm. The waveguide is coated with gold of thickness 100 nm using the sputtering technique in order to introduce surface plasmon resonance at the sides and the top of the structure. Hence, a polarization-independent waveguide is achieved and the light confinement in both the TM and TE modes are studied. Supermodes occurring from the fundamental dielectric mode coupled with plasmonic supermode at the resonance peak are investigated. This paper presents the results obtained through simulations and also experimental validation. With this structure, there are two dielectric-plasmon supermodes with two resonance peaks separated by 50 nm. A red shift is observed when the refractive index of the cladding material increases. The cladding material includes water (n=1.333) and iso-propanol solutions with refractive indices of 1.344, 1.351 and 1.365. The gold-coated ormocomp waveguide has sensitivity of about 544.55 nm/RIU with a resolution of 5.3x10-3 RIU. Permanent repository link
