Silicon-based Integrated Optics: Waveguide Technology to Microphotonics

ABSTRACTUsing a waveguide spectrometer chip as an example, we describe how high index contrast waveguides systems such as silicon-on-insulator can be combined with microphotonic design rules to extend the performance of waveguide devices. The challenges arising in the implementation of silicon microphotonic technology are discussed, and recent work addressing the issues of waveguide coupling, polarization sensitivity, waveguide loss and massively parallel data acquisition is reviewed.

Development Prospects

Mode-division multiplexing (MDM) technology has drawn tremendous attention for its ability to expand the link capacity within a single-wavelength carrier, paving the way for large-scale on-chip data communications. In the MDM system, the signals are carried by a series of higher-order modes in a multi-mode bus waveguide. Hence, it is essential to develop on-chip mode-handling devices. Silicon-on-insulator (SOI) has been considered as a promising platform to realize MDM since it provides an ultra-high-index contrast and mature fabrication processes. In this paper, we review the recent progresses on silicon integrated nanophotonic devices for MDM applications. We firstly discuss the working principles and device configurations of mode (de)multiplexers. In the second section, we summarize the multi-mode routing devices, including multi-mode bends, multi-mode crossings and multi-mode splitters. The inverse-designed multi-mode devices are then discussed in the third section. We also provide a discussion about the emerging reconfigurable MDM devices in the fourth section. Finally, we offer our outlook of the development prospects for on-chip multi-mode photonics.

Magneto Optic

ABSTRACTSurface activated direct bonding of a magnetooptic garnet crystal to a Silicon-On-Insulator (SOI) wafer is discussed for the application to waveguide optical nonreciprocal devices. An interferometric waveguide isolator is discussed that uses nonreciprocal phase shift brought about by a first-order magneto-optic effect. In an SOI waveguide, the low refractive index of buried oxide layer enhances the magneto-optic phase shift. This contributes to reduce the device size together with the strong field confinement of high index contrast waveguide. The interferometric isolator can be extended to an optical circulator by adopting appropriate 3-dB directional couplers to construct a Mach-Zehnder interferometer.
