  • Silicon quantum dot laser
    Patent number: 5703896
    Abstract: Dynamic variation in the color produced by a silicon quantum dot laser is achieved by utilizing segmented sections or patches of quantum dots of differing sizes to produce different colors of light. The amount of each color of light produced is controlled by selectively biasing the segments of quantum dots. The light is caused to resonate coherently and is emitted out by a diffraction grating. The dynamic variation in the color of light produced by such a device makes it useful as a multicolor pixel in a color display of images.
