We present an ultracompact (15.3 μm long) and high-efficiency silicon-on-insulator polarization rotator designed for polarization-diversified circuits. The rotator is comprised of a bilevel-tapered TM0-to-TE1 mode converter and a novel bent-tapered TE1-to-TE0 mode converter. The rotator has a simulated polarization conversion loss lower than 0.2 dB and a(More)
We present the design and fabrication of complimentary metal-semiconductor field-effect transistors (MESFETs) monolithically integrated on a high-speed silicon photonics platform. The transistors were built in an existing silicon photonics process without any additional process steps or modifications to maintain consistent photonics performance. The MESFETs(More)
