Compact Focusing Grating Couplers for Silicon-on-Insulator Integrated Circuits [PDF]
IEEE Photonics Technology Letters, 2007 —We report experimental results on compact and broadband focusing grating couplers, both in silicon-on-insulator (SOI) and gold on SOI. An eight-fold length reduction of the coupling structure from fiber to photonic wire in SOI, as com-pared to a linear ...

High-Q microresonators on 4H-silicon-carbide-on-insulator platform for nonlinear photonics
Light: Science & Applications, 2021 The realization of high-quality (Q) resonators regardless of the underpinning material platforms has been a ceaseless pursuit, because the high-Q resonators provide an extreme environment for confining light to enable observations of many nonlinear ...

IEEE Transactions on Antennas and Propagation, 2020 Two high-gain flat array antenna designs operating in the 320–400 GHz frequency range are reported in this article. The two antennas show the measured gains of 32.8 and 38 dBi and consist of a $16\times16$ (256) element array and a $32\times32$ (1024)

Silicon-on-insulator nanophotonics [PDF]
SPIE Proceedings, 2005 Nanophotonics promise a dramatic scale reduction compared to contemporary photonic components. This allows the integration of many functions onto a chip. Silicon-on-insulator (SOI) is an ideal material for nanophotonics. It consists of a thin layer of silicon on top of an oxide buffer.

Optimization of photoluminescence from W centers in a silicon-on-insulator. [PDF]
Optics Express, 2019 W centers are trigonal defects generated by self-ion implantation in silicon that exhibit photoluminescence at 1.218 µm. We have shown previously that they can be used in waveguide-integrated all-silicon light-emitting diodes (LEDs). Here we optimize the
