Fujitsu and Mitsui link up over optical laser technology

Tash Shifrin

Fujitsu is to launch a company to commercialise high-performance quantum dot lasers for the optical telecommunications industry, in a joint venture with general trading firm Mitsui.

The new venture, QD Laser, will market products based on quantum dot technology developed through a research partnership between Fujitsu Limited, Fujitsu Laboratories and the University of Tokyo, Japan.

It is based on quantum dots – semiconductor particles that are a single nanometer, or a billionth of a metre, in size.

Quantum dot lasers offer higher performance than conventional  semiconductor lasers, with better temperature-independent operation, lower power consumption, improved long-distance transmission and higher speeds.

They are expected to become a core technology in optical telecommunications, which are carrying rapidly increasing volumes of data traffic.

QDL will offer quantum dot lasers to the optical telecommunication light source market for use in  optical access and optical local area networks inside buildings.
Mitsui will provide equity investment and support the new venture with strategy planning, operational management and global marketing.
