[3] In 2002, together with his former students Ichiro Aoki and Scott Kee, he cofounded Axiom Microdevices Inc. based on their invention of the Distributed Active Transformer (DAT), which made it possible to integrate RF CMOS power amplifiers suitable for cellular phones in CMOS technology.
[6] These were followed by a 77-GHz phased array transceiver (transmitter and receiver) with on chip antennas that established the highest level of integration in mm-wave frequency applications and was a complete radar-on-a-chip.
They demonstrated various phased array transmitters around 0.3THz with beam steering using the distributed active radiator (DAR) architecture in 2011.
[14][15][16][17] Between 2014 and 2018, his lab demonstrated several major advances in imaging, projection, and sensing technology on silicon photonic platforms.
[18][19][20] In 2014, they showed the first silicon nanophotonic optical phased array transmitter capable of dynamic and real-time image projection, therefore serving as a lensless projector.
