Abstract:
Because of their efficiency, small size and reliability high power laser diodes are used for
numerous tasks, such as the pumping of solid state lasers, second harmonic generation and the pumping of
rare earth fibre amplifiers. The next generation of optical networks will most likely use Raman amplifiers
for optical regeneration instead of Erbium doped fibre amplifiers. Up to now the widespread use of Raman
has been limited by the availability high power pump modules.
In this thesis we examine a new type of waveguide design for use in high power laser diodes, a
unique feature of this design is that the last mode before cut-off is predominantly confined to the low index
region of the waveguide structure. As this is quite a counter intuitive result, structures based on this design
concept, are for shorthand purposes referred to as Lo-guides. The subject matter in this thesis is concerned
with the investigation of waveguide structures which could potentially facilitate the production of higher
power single spatial mode laser diodes.
