Quantum Dot Lasers
Quantum-dot lasers are advanced light-emitting devices that use tiny semiconductor particles, known as quantum dots, to generate laser light. These dots are so small that they confine electrons in three dimensions, which enhances their efficiency and allows for precise control over the emitted light's properties, such as color and intensity. As a result, quantum-dot lasers are more effective than traditional lasers, offering energy savings and the potential for smaller, lighter devices. They have applications in telecommunications, medical technology, and displays, making them a promising technology for the future.
