Abstract :
Summary from only given. We have reported the successful realisation of the type of a curved-grating DBR semiconductor laser that was previously proposed theoretically. Single-frequency generation was observed and far-field measurements showed good agreement with our prediction for lateral beam behaviour. Future studies will concentrate on near-field investigations and improved devices with non-absorbing c-DBR mirrors, which will be achieved using the quantum well intermixing technique. High power operation in CW and Q-switched regimes will then be investigated.
