Lighting up silicon nanoparticles with Mie resonances

Nature Communications, 2018
As an indirect semiconductor, silicon shows notoriously inefficient luminescence. Here, the authors utilize the Mie resonances in silicon nanoparticles to demonstrate visible white-light emission, both from free-standing spheres and particles etched on a

Design of an Athermal Interferometer Based on Tailored Subwavelength Metamaterials for On-Chip Microspectrometry

IEEE Photonics Journal, 2019
Temperature dependence is one of the main challenges of the silicon-on-insulator platform due to the large thermo-optic coefficient of its core material.

Measurement of thermal conductance of silicon nanowires at low temperature

, 2006
We have performed thermal conductance measurements on individual single crystalline silicon suspended nanowires. The nanowires (130 nm thick and 200 nm wide) are fabricated by e-beam lithography and suspended between two separated pads on Silicon On ...

Reflectionless grating coupling for silicon-on-insulator integrated circuits [PDF]

, 2011
We propose a novel grating coupler design which is inherently reflectionless by focusing the reflected light away from the entrance waveguide.

All-Optical Wavelength Multicasting in Quadruple Resonance-Split Coupled Silicon Microring Cavity

IEEE Photonics Journal, 2018
We demonstrate an all-optical four-channel wavelength multicasting in a coupled silicon microring resonator system. The scheme is based on two-photon-absorption-induced free carrier dispersion in silicon.
