| Abstract: | We present an improved version of the twin-channel laser as a prototype for a new concept in semiconductor laser array structures with a well controlled far-field beam pattern. The laser device constitutes the first CW semiconductor laser array structure on a p-type GaAs substrate using current-blocking layers and yields improved current utilisation and efficiency over previous structures. |
