Photonic ADC: overcoming the bottleneck of electronic jitter.
TLDR
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
TLDR
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.
TLDR
We demonstrate a monolithic photonic integration platform that leverages the existing state-of-the-art CMOS foundry infrastructure. Expand
Integrated phased array for wide-angle beam steering.
We demonstrate an on-chip optical phased array fabricated in a CMOS compatible process with continuous, fast (100 kHz), wide-angle (51°) beam-steering suitable for applications such as low-cost LIDARExpand
Open foundry platform for high-performance electronic-photonic integration.
TLDR
This paper presents photonic devices with 3 dB/cm waveguide loss fabricated in an existing commercial electronic 45 nm SOI-CMOS foundry process. Expand
Adiabatic thermo-optic Mach-Zehnder switch.
In this Letter, we propose and demonstrate a high-speed and power-efficient thermo-optic switch using an adiabatic bend with a directly integrated silicon heater to minimize the heat capacity andExpand
A high-Q tunable interior-ridge microring filter
A tunable interior-ridge microring filter is demonstrated with a high quality factor of 1.5×105, while achieving a thermal tuning efficiency of 5.5μW/GHz. The filter demonstrates a record lowExpand
Large-Scale Silicon Photonic Circuits for Optical Phased Arrays
We review recent advances in integrated large-scale optical phased arrays. The design and fabrication of large-scale optical phased arrays using silicon photonic circuits are discussed from deviceExpand
Two-dimensional apodized silicon photonic phased arrays.
In this Letter, we demonstrate an 8×8 apodized silicon photonic phased array where the emission from each of 64 nanoantennas was tailored to exhibit Gaussian-shaped intensity distributions in theExpand
