Photonic ADC: overcoming the bottleneck of electronic jitter.
In this work, the potential of the photonic approach is demonstrated by sampling a 41 GHz signal with record 7.0 ENOB with a discrete-component photonic ADC built from discrete components. Expand
Large-scale nanophotonic phased array
We present a large-scale two-dimensional nanophotonic phased array (NPA), in which 64 × 64 (4,096) optical nanoantennas are densely integrated on a silicon chip within a footprint of 576 μm with all of the nanoantennaas precisely balanced in power and aligned in phase to generate a sophisticated radiation pattern in the far field.

An ultralow power athermal silicon modulator
Silicon photonics has emerged as the leading candidate for implementing ultralow power wavelength–division–multiplexed communication networks in high-performance computers, yet current componentsExpand
Nanophotonic integration in state-of-the-art CMOS foundries.
