NL Nanosemiconductor said it has developed a laser chip that will enable cost-effective wavelength division multiplex approaches to optical communications using silicon photonic technology, including silicon-based arrayed waveguides and light modulators.

A single-mode continuous (CW) laser with a spectral width of >20 nm and spectral wavelength between 1200 and 1320nm is being put into production at NL Nanosemiconductor's facilities in Dortmund, Germany.

Alexey Kovsh, COO at NL Nanosemiconductor, said, "The uniqueness of our laser is the width (25 nm) and uniform shape (less than 3 dB modulation at 0.5 nm resolution) of the spectrum in the lasing regime. Of further importance is the high reproducibility of the lasing spectrum shape. We managed to develop a way to get a laser to lase with a very wide emission spectrum, which is of course opposite to the fundamental nature of lasing -- at a very narrow spectrum."
