Abstract:
The performance of a multisection distributed Bragg reflector (DBR) semiconductor laser emitting around 1.06 µm is experimentally and theoretically investigated. A thermal-induced change of the refractive index implied by an increase in the injection current yields nearly periodic transitions between neighbouring cavity modes. These transitions are explained by means of a modal analysis and by numerical simulations based on the travelling wave model.
