The Research Center for Silicon Nano-Science (SNS) of the Advanced Research Laboratories (ARL) at Tokyo City University developed a silicon-based LED. It is made by embedding Ge microparticles (quantum dots) with a diameter of several tens of nanometers to 100nm in the i-layer of a Si-based device with a pin structure. The university claims that the light emitting device will help realize a silicon (Si) photonics because it can be produced by using a manufacturing process compatible with a CMOS process and possibly is capable of laser oscillation.

Silicon is a lower cost raw material, and it has greater economies of scale in manufacturing than sapphire wafers most often used.
