205:(2D) optical phased array receiver capable of imaging simple 2D patterns without a lens using a very thin optical synthetic aperture of a few microns, thereby demonstrating a lensless flat camera for the first time. In 2018, they demonstrated the world's first all-integrated optical gyroscope, whose principle of operation is based on the

Between 2014 and 2018, his lab demonstrated several major advances in imaging, projection, and sensing technology on silicon photonic platforms. In 2014, they showed the first silicon nanophotonic optical phased array transmitter capable of dynamic and real-time image projection, therefore serving as

that performed direct 3D imaging at meter range with a 15-micron depth resolution. In 2016, they devised and implemented a one-dimensional (1D) integrated optical phased array receiver which could image a barcode directly from the surface of a chip, followed in 2017 by an integrated two-dimensional
187:
He and his students also demonstrated the world's first radar-on-a-chip in silicon technology in 2004, showing a 24-GHz 8-element phased array receiver and a 4-element phased array transmitter in CMOS. These were followed by a 77-GHz phased array transceiver (transmitter and receiver) with on chip

He and his team are also responsible for the development of an all-silicon THz imager system, where an integrated CMOS microchip was used in conjunction with a second silicon microchip to form an active THz imaging system, capable of seeing through opaque objects. They demonstrated various phased

In 2013, he and some of his team members demonstrated a complete self-healing power amplifier, which through an integrated self-healing strategy, could recover from various kinds of degradation and damage including aging, local failure, and intentional laser blasts.

array transmitters around 0.3THz with beam steering using the distributed active radiator (DAR) architecture in 2011. Various applications of this system appear in security, communications, medical diagnostics, and the human-machine interface.

He and his team have also developed systems and technologies for wireless power transfer at a distance. In 2017, he co-founded GuRu
Wireless (formerly Auspion, Inc.), which commercializes wireless power transfer technology for consumers.
