Silicon has long been established as the material of choice for the microelectronics industry.
This is not yet true in photonics, where the limited degrees of freedom in material design …

Hyperbolic metamaterials (HMMs) have recently garnered much attention because they
possess the potential for broadband manipulation of the photonic density of states and …

Group IV lasers are expected to revolutionize chip-to-chip optical communications in terms
of cost, scalability, yield, and compatibility to the existing infrastructure of silicon industries …

To address the limitations in device speed and performance in silicon-based electronics,
there have been extensive studies on silicon optoelectronics with a view to achieving …

We demonstrate cryogenic, electrically injected, waveguide-coupled Si light-emitting diodes
(LEDs) operating at 1.22 μm. The active region of the LED consists of W centers implanted in …

Efficient coupling to integrated high-quality-factor cavities is crucial for the employment of
germanium quantum dot (QD) emitters in future monolithic silicon-based optoelectronic …

The missing piece in the jigsaw of silicon photonics is a light source that can be easily
incorporated into the standard silicon fabrication process. Here, silicon laser‐like emission is …

W centers are trigonal defects generated by self-ion implantation in silicon that exhibit
photoluminescence at 1.218 µm. We have shown previously that they can be used in …

Silicon is now firmly established as a high performance photonic material. Its only weakness
is the lack of a native electrically driven light emitter that operates CW at room temperature …

Active slot waveguides were fabricated by embedding low-index Er/Yb silicate material in
high-index silicon. A 1.7 dB signal enhancement at 1.53 µm in a 6 mm-long slot waveguide …
