A 10 Gbit/s quantum dot laser that is insensitive to temperature fluctuation for use in optical data communications and optical networks has been developed using this technology. The laser is capable of high-speed operation at 1.3 μm wavelengths, at temperatures from 20 °C to 70 °C. It works in optical data transmission systems, optical LANs ...
Therefore, the quantum dot is an emitter of single photons. A key challenge in making a good single-photon source is to make sure that the emission from the quantum dot is collected efficiently. To do that, the quantum dot is placed in an optical cavity. The cavity can, for instance, consist of two DBRs in a micropillar (Fig. 1).
Quantum dot laser: wide range. Medicine (laser scalpel, optical coherence tomography), display technologies (projection, laser TV), spectroscopy and telecommunications. Quantum well laser: 0.4-20 μm, depending on active region material. Telecommunications: Hybrid silicon laser: Mid-infrared: Low cost silicon integrated optical communications
Quantum dots have properties intermediate between bulk semiconductors and discrete atoms or molecules. Their optoelectronic properties change as a function of both size and shape. [5] [6] Larger QDs of 5–6 nm diameter emit longer wavelengths, with colors such as orange, or red. Smaller QDs (2–3 nm) emit shorter wavelengths, yielding colors ...
Bala S. Manian is an Indian-born Silicon Valley entrepreneur who has started a string of medical technology companies such as ReaMetrix, Digital Optics and Quantum Dot Corporation. [1] [2] Some of the resulting technologies have also had applications in the film industry, earning Manian an Academy Award certificate for technical achievement. [1]
The first working model of the laser was created at Hughes Research Laboratories in 1960 by Theodore Maiman (1927–2007). HRL began research on atomic clocks in 1959. In the late 1970s they produced experimental maser oscillators for NRL, which eventually led to space-based GPS atomic clocks. HRL began research on ion propulsion in 1960. [4]

Quantum dots (QDs) are nano-scale semiconductor particles on the order of 2–10 nm in diameter. They possess electrical properties between those of bulk semi-conductors and individual molecules, as well as optical characteristics that make them suitable for applications where fluorescence is desirable, such as medical imaging.
