“Although silicon photonics is a perfect solution on paper, for more than 30 years scientists have struggled to surmount its various shortcomings. While silicon is opaque in the visible spectrum, it is transparent at infrared wavelengths used in optical transmission, so it is good at guiding light. Where it falls down is in emitting light. Silicon photonics expert Lars Frandsen from the Technical University of Denmark (DTU) gets into the technical details: “The electronic bandgap of silicon makes it transparent in the telecommunication wavelength range, but it is an in-direct bandgap, which make silicon a very poor emitter.” This is why the lasers that drive optical communications are made of more exotic materials such as indium-phosphide (InP) and gallium-arsenide (GaAs).”
We have been involved in developing silicon infrared source for more than eight years.

Many novel ways to produce light
Many ways to generate light in semiconductors. One novel approach is to use the avalanche breakdown to do this, for example. "Since electron-hole pairs are produced during avalanche breakdown, some radiative recombination occurs. Both the electrons and the holes can be heated by the electric field. Since it is attributed to the hot-carrier population under the condition of avalanche breakdown, the light emission can be used for high-speed light-emitting devices, high-speed light amplifiers, and the analytic investigation of hot carrier distribution."

A people counter is an electronic device that is used to measure the number of people traversing a certain passage or entrance. They are commonly used by retail establishments to judge the effectiveness of marketing campaigns, building design and layout, and the popularity of particular brands.
