Scientists at Princeton University invent the smallest laser of the world. The new laser is the perfect demonstration of the basic interaction of light and moving electrons. It is similar to a single rice grain in terms of size.
The laser is powered by a single electron. Hence, it requires electricity of one-billionth that is equal to the electricity consumption of a hair dryer.
Jacob Taylor, an assistant professor of the University of Maryland –National Institute of Standards and Technology states that the device is a significant The device is as small as scientists can invent with a single electron.
Scientists utilized quantum dots for the creation of the smallest laser. Quantum dots are nonocrystals that are composed of semiconductor. These dots are small enough to exhibit quantum mechanical process. The combination of two quantum dots is considered as the fundamental unit of information in quantum computers.
Researchers connected thin nano wires with quantum dots in order to develop the tiny laser. They placed these quantum dots at a distance of nearly six millimeters. They were located in a semi conductor material known as Niobium. It compels the electrons to travel from one quantum dot to another quantum dots. The process mechanically controls the reactions of Microwave spectrum
The chief goal of the experts was to discover different uses of double quantum dots. However, they came up with this innovative discovery during the study of quantum dots.
