Reliable 1.3 μm high speed trenched buried heterostructure lasers grown entirely by atmospheric MOVPE

The authors report on reliable high-power wide-bandwidth 1.3 mu m trenched buried heterostructure (TBH) lasers grown by atmospheric MOVPE. The devices have bandwidths of up to 11 GHz and maintain excellent CW performance and long lifetimes. Data are presented for all of the above parameters, along with a discussion of the design considerations of the device structure.
