Abstract :
This paper investigates the impact of lateral radiation losses in ridge waveguide (RW) lasers emitting around 1064 nm is investigated. The RWs are fabricated by dry etching of pairs of trenches with widths between 2.5 and 20 μm into the epitaxial layer structure in order to define the RWs.
