A silicon-on-insulator slab for topological valley transport

Nature Communications, 2019
Backscattering is one of the major factors that limit the performance of integrated nanophotonics. Here, He et al. realize topologically protected, robust and unidirectional coupling as well as optical transport on a silicon-on-insulator platform by ...

Accurate Chromatic Dispersion Characterization of Photonic Integrated Circuits

IEEE Photonics Journal, 2012
An accurate technique to characterize chromatic dispersion and its slope versus wavelength is reported. The method is based on a heterodyne Mach-Zehnder interferometer, which is immune to thermal phase noise by using a counterpropagating reference beam ...

Design and Measurement of Ring-Gate Single Photon Avalanche Diode With Low Dark Count Rate

IEEE Photonics Journal, 2020
Single photon avalanche diodes (SPAD) based on avalanche effect have been widely used in the detection of extremely weak light signals. Conventional SPAD devices manufactured with silicon-based CMOS technology have a high dark count rate (DCR), making it

Subwavelength Silicon Nanophotonics

Latin America Optics and Photonics Conference, 2010
A new optical waveguide principle is proposed, exploiting subwavelength grating effect. We demonstrate first subwavelength grating waveguides, including practical components such as highly efficient fibre-chip couplers, waveguide crossings and microspectrometer chips.

Nonlinear silicon nanophotonics for mid-infrared applications [PDF]

2011 ICO International Conference on Information Photonics, 2011
The silicon nanophotonic wire platform can be applied toward development of integrated optical devices for the generation and processing of mid-infrared light signals. The demonstration of a mid-infrared optical parametric amplifier will be reviewed, and recent work aimed at expanded gain bandwidth and reduced pump power requirements will be presented.

Sunlight-thin nanophotonic monocrystalline silicon solar cells

, 2017
Introducing nanophotonics into photovoltaics sets the path for scaling down the surface texture of crystalline-silicon solar cells from the micro-to the nanoscale, allowing to further boost the photon absorption while reducing silicon material loss ...

Stable Excitation of Orbital Angular Momentum States in Air-Core Fiber Seeded by an Integrated Optical Vortex Beam Emitter

IEEE Photonics Journal, 2020
We experimentally demonstrate excitation of orbital angular momentum states in an air-core fiber by a silicon integrated vortex beam emitter which is designed and fabricated to match the modes supported by the fiber. The coupling loss is measured to be &#

Bandwidth steering in HPC using silicon nanophotonics [PDF]

Proceedings of the International Conference for High Performance Computing, Networking, Storage and Analysis, 2019
As bytes-per-FLOP ratios continue to decline, communication is becoming a bottleneck for performance scaling. This paper describes bandwidth steering in HPC using emerging reconfigurable silicon photonic switches. We demonstrate that placing photonics in the lower layers of a hierarchical topology efficiently changes the connectivity and consequently ...
