Synopsis: Domenii: Photonics & laser: Photonics & laser generale: Laser: Laser devices: Laser source:

in cooperation with Thales Research and Technology in the United kingdom, say the tuneable laser source integrated on silicon is a groundbreaking achievement in efforts to secure fully integrated transceivers.

integrating laser sources on a silicon platform. And while the laser structures have so far only been demonstrated with optical pumping,

When mounted between the laser source and object the filter divides the laser light into separate blue

However in spite of intensive research a laser source that is compatible with the manufacturing of chips is not yet achievable according to the head of Semiconductor Nanoelectronics (PGI-9). The basis of chip manufacturing is silicon an element of main group IV of the periodic table.

and thus make it a usable laser source. The scientists at Julich's Peter Grunberg Institute have succeeded now for the first time in creating a real direct main group IV semiconductor laser by combining germanium and tin

The laser sources alternatingly emit light from only one chip at two different stabilized wavelengths, which are defined by gratings implemented into the semiconductor chip.

Now, efficient and compact laser sources are at hand emitting in the near-infrared on multi-watt level (CW operation) with a narrow-band spectrum and a stigmatic, nearly Gaussian laser beam
