The world's first blue-violet laser diode, a light source for large capacity optical disc systems like advanced DVDs, has a low noise beam structure
Photonic Products can supply what it says is the world's first blue-violet laser diode, with a new low noise beam structure produced using ion implantation, from Sanyo.
The stable beam structure boasts lower noise, and current consumption achieving higher performance compared with conventional blue-violet laser diodes.
This structure makes Sanyo's blue-violet laser diode an optimum light source for large capacity optical disc systems like advanced DVDs.
The laser diode is easily mass-produced because the stable beam structure reduces the number of fabrication steps while the top and bottom electrodes structure reduces chip size.
Demand for the laser diode is expected to rise sharply as more large capacity optical disc systems become available and more widely used.
Data sheets for this and other fibre optic components are available from the Photonic Products website.
