To take communications to the next level, laser technologies must improve in terms of cost, efficiency and robustness. Fortunately, those improvements are in the works. Whether traveling through free space or over a fiber, lasers power data delivery – so laser innovations can up data rates, cut costs and improve capabilities. Arguably, the greatest need for better communications lies in data centers, the conglomeration of computers and storage that make the online world go. Networking giant Cisco predicted in October 2013 that global data center traffic would triple between...Read full article

    indium phosphide
    Indium phosphide (InP) is a compound semiconductor material composed of indium (In) and phosphorus (P). It belongs to the III-V group of semiconductors, where elements from groups III and V of the periodic table combine to form a variety of important semiconductor materials. Indium phosphide is known for its favorable electronic and optical properties, making it widely used in the fabrication of optoelectronic devices. Key features and properties of indium phosphide include: Bandgap:...
    infrared
    Infrared (IR) refers to the region of the electromagnetic spectrum with wavelengths longer than those of visible light, but shorter than those of microwaves. The infrared spectrum spans wavelengths roughly between 700 nanometers (nm) and 1 millimeter (mm). It is divided into three main subcategories: Near-infrared (NIR): Wavelengths from approximately 700 nm to 1.4 micrometers (µm). Near-infrared light is often used in telecommunications, as well as in various imaging and sensing...
    nanotechnology
    The use of atoms, molecules and molecular-scale structures to enhance existing technology and develop new materials and devices. The goal of this technology is to manipulate atomic and molecular particles to create devices that are thousands of times smaller and faster than those of the current microtechnologies.
    power
    With respect to a lens, the reciprocal of its focal length. The term power, as applied to a telescope or microscope, often is used as an abbreviation for magnifying power.
    quantum dots
    A quantum dot is a nanoscale semiconductor structure, typically composed of materials like cadmium selenide or indium arsenide, that exhibits unique quantum mechanical properties. These properties arise from the confinement of electrons within the dot, leading to discrete energy levels, or "quantization" of energy, similar to the behavior of individual atoms or molecules. Quantum dots have a size on the order of a few nanometers and can emit or absorb photons (light) with precise wavelengths,...
    temporal coherence
    A characteristic of laser output, calculated by dividing the speed of light by the linewidth of the laser beam. The temporal coherence length of different lasers thus varies from a few centimeters to many meters.
    vertical-cavity surface-emitting laser
    A vertical-cavity surface-emitting laser (VCSEL) is a type of semiconductor laser diode that emits light vertically from the surface of a semiconductor wafer. VCSELs are commonly used in various applications, including data communication, optical sensing, and optical interconnects. vertical-cavity surface-emitting laser suppliers → Unlike edge-emitting lasers, which emit light from their edges, VCSELs emit light from the top surface of the device. This vertical emission is...
