Designed at Nortel optical lab at 3500 Carling Ave., Ottawa, this was an early prototype produced at Nortel's Paignton, UK facility in 2000. Production continued after Bookham Technology's purchase of Nortel's optical components division. including the Paignton facility. Production versions of this prototype accounted for 20 per cent of Bookham's sales in 2005.
Function
A device used to provide and modulate a laser light source for a fibre optic network.
Technical
This is a direct modulated laser: i.e. it uses an electrical current to directly turn on the laser on and off. The laser is distributed feedback (DFB) device consisting of a gallium indium arsenide phosphide (GaInAsP) chip. Its buried heterogeneous (buried HET) internal structure improves the thermal performance of the laser, making it less susceptible to the effects of dispersion. This increases he effective range of the device to 360km at 2.5 Gbps. Its primary application is in wavelength division multiplexed (WDM) long distance fibre optic circuits.
