Bookham, Inc., has launched a new 'green' vertical cavity surface emitting laser, VCSEL, featuring the patented Bookham wide oxide aperture design and consumes less than 5mW of power which is 50 percent less than previous offerings.
The VCSEL is targeted at the optical computer mouse market, as well as other consumer, battery powered applications where power consumption is an important factor in product design.
The singlemode 850nm is polarization stable, and retains the reliability, robustness and resistance to ESD (electro-static discharge) of previous, higher power consumption devices. The VCSEL is available in a standard TO package interface.
Bookham has now shipped in excess of 13 million polarization stable VCSELs. In January 2008, the company announced the transition of VCSEL manufacturing to its High Power Laser facility in Zurich, Switzerland, to meet increasing volume demand from consumer applications.
"Power consumption is a major consideration for designers of any product that is battery powered, including mobile handsets, mobile sensing devices and, of course, optical navigation systems including computer mice, where we are seeing huge demand for high performance, polarization stable VCSELs," said Karlheinz Gulden, Director VCSEL Business at Bookham. "Through optimization of the laser design, we have successfully reduced power consumption by over 50 percent and retained all the reliability and stability performance benefits of our unique, patented wide oxide aperture design that has been shipping for more than eight years.
"Our state-of-the-art manufacturing facility allows us to meet volume demand for VCSELs for optical engines in a wide variety of markets."
