Abstract
The beam characteristic of continuously tunable twin-guide (TTG) laser diod
es has been investigated and it was observed that the beam profile is chang
ed during tuning. This affects the coupling of the laser light into a fibre
interface, leading to a reduction in transmitted optical power. It is show
n how the coupling losses during tuning can be compensated for. An observed
shift in the lateral far field has a high potential for the realisation of
a continuously beam steering device.
