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
