Laser Maker Acquires Rival

NL Nanosemiconductor GmbH announced it has acquired Zia Laser Inc. of Albuquerque, N.M., for an undisclosed amount. Both companies are involved in the research and the commercialization of quantum dot semiconductor laser technology and have had a cooperative relationship in the past.

NL Nanosemiconductor supplies epitaxial wafers with quantum dots grown by molecular beam epitaxy (MBE) and high-power laser modules, as well as broadband and modelocked lasers. Its headquarters are based in Dortmund and its US offices are in San Jose, Calif. The company said its long-term development focus is to improve the performance of semiconductors by delivering lasers for interchip and intrachip timing and signal distribution.

Quantum dot semiconductor laser maker Zia Laser was spun off from the Center for High Technology Materials at the University of New Mexico in June 2001. It has attracted $22 million in venture capital investments since then.

Alexey Kovsh, COO of NL Nanosemiconductor, said while quantum dot research is being carried out in labs around the world, it hasn't yet reached its full potential.  “Combining the two leading quantum dot companies’ separately developed wafer growth expertise, laser manufacturing techniques as well as product and IP portfolio will further accelerate the exploitation of quantum dot lasers’ unique properties to deliver fundamental performance improvements in existing applications as well as enabling completely new applications. In fact, cooperation already underway has so far yielded outstanding results which have exceeded expectations,” he said. 

"Today we see the clear potential of quantum dot lasers to enable new applications -- providing high-speed optical interconnect between chips as well as delivering optical timing within the next generation of high-performance ICs such as microprocessors, graphics and memory chips," said Jürgen Kurb, CEO of NL Nanosemiconductor. "In addition, applications such as optical imaging, medical treatment and multilambda optical communications will benefit from the unique advantages of quantum dot technology, particularly the broad gain spectrum and unique wavelength range of 1.1 -1.3 µm.”

Glossary
broadband
Indicating a capability to deal with a relatively wide spectral bandwidth.
epitaxial
Epitaxial refers to the growth of a crystalline layer on a crystalline substrate in such a way that the orientation of the crystal lattice of the growing layer is related to that of the substrate. In other words, epitaxial growth involves the deposition of a thin film or layer of material onto a crystalline substrate in a way that maintains a well-defined relationship between the atomic arrangement of the layer and the substrate. Epitaxial growth is commonly used in the manufacturing of...
nano
An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
photonics
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
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,...
