Abstract

We have analyzed experimentally and theoretically the modal properties of a semiconductor ring laser and the wavelength jumps that occur in connection with directional switching above threshold. A transfer matrix analysis allow us to explain the transfer function measurements when amplified spontaneous emission in the cavity is accounted for. Moreover the transfer matrix analysis permits to determine the threshold condition for the laser modes, which split in two branches due to the symmetry breaking imposed by the output coupler and output waveguides. The wavelength jumps displayed by the device above threshold are interpreted with the frequency splitting and threshold difference between these two branches of solutions, together with the redshift of the material gain.
