High power operation of DFB laser diodes with a decoupled confinement heterostructure

Summary form only given. As a suitable epitaxial structure for high power and high brightness LDs, we have proposed a decoupled confinement heterostructure (DCH) and reported on the characteristics of the devices. Here we present the results from a grating integrated structure, narrow-stripe DFB LD, based on DCH technology, and reveal the potential for single longitudinal and single spatial mode operation.
