Abstract

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