Direct pumping silicon laser available for more powerful fiber optic network

According to researchers at Brown University in the United States recently said they have developed the first directly pumped silicon laser that is said to help make faster or more powerful computers or fiber optic networks. According to Brown, scientists have used neon-to-sapphire materials to make lasers since 1960, but silicon structures can not form the proper electron alignment to emit light. Three researchers, led by engineering physics professor Jimmy Xu, said they developed a direct-pumped silicon laser by changing the atomic structure of silicon by using a nanoscale template to drill billions of small pieces of silicon The hole creates a "weak but real" laser. The template, also known as the anodized aluminum "mask", is about 1 square millimeter and is said to have billions of micropores that are evenly sized and sized. Jimmy Xu pointed out that although the silicon laser has become possible, but not practical. In order to commercialize the technology, it has to be engineered to be even more powerful and capable of operating at room temperature, but for now it can only work at -200 ° C. The researchers said that materials with both silicon and laser optics will find room in the electronics and communications industries to help make faster, more powerful computers or fiber optic networks.
